Here's a link to his ConnectOne example (http://mackrackit.com/mac/ichip/ichip.html).

Pros: The ConnectOne modules have a complete set of internet protocols and all the coding is similar to that in the mackrackit example. Configuration can be done via the ethernet or serial connection. The modules do all of the heavy lifting. IMO, these are the easiest to use.

Drawbacks: Their modules take up more real estate than some others and mounting them to a mainboard is problematic in some cases. They do not fit breadboards. The code burden of the AT commands can add up quickly.

Another drawback with the ConnectOne is it can not be setup to use "non-standard" ports when using it as a web server. Port 80 and 443 are it.

About a year ago I asked them about it and they told me they were working on new firmware. Maybe the new firmware is out but I have not seen it..

Dave, I am considering using a ConnectOne MiniSocketWiFi Module for a battery operated wireless application because it has a shutdown mode that only consumes 40 uA...which is lowest consumption that we have found in any other wireless module.

We intend on sending it data via its asynchronous serial interface (no flow control) for WiFi transmission. However, after reviewing the data sheet for the MiniSocketWiFi module we are confused as to whether it requires use of the DTS and DSR handshaking interfaces. Your posting here doesn't say which ConnectOne module you are using, but I would very much like to see a reference design if you have one and an explanation of how you are wiring the serial interface...maybe even a schematic?

Would also like to know from your example the delay time from AT message transmission to the ConnectOne until the WiFi message is actually transmitted via WiFi if you by chance have measured it or can estimate it?

Just tie the handshaking lines (nCTS,nRTS) together if you are not using them.

In the ethernet shields, I bring them out to a point where you can solder a wire jumper between them.

I've put up a web page with the shields and some other related things here...


http://davehouston.org/Arduino.htm

All the connections are shown on the shields.

I don't have the iWiFi but only the SocketLAN so I cannot answer about the delay. Maybe the other Dave can.

In general I've found that the translation delay between serial and other protocols isn't noticed until you try something intensive like updating firmware over the link where the translation time and handshaking for error checking become a larger factor.

As for the current draw, the various serial-to-WiFi adapters are all over the map. I was considering a shield using a WIZNet module (which I do have) until I saw it used about twice as much current when transmitting than others.

BTW, look into BR type batteries if you haven't already.

I have only used the Nano LANReach, Nano SocketLAN, and Nano Socket iWiFi modules. The only data connections used are the TX and RX from MCU to the ConnectOne module.

I never noticed a delay and have not taken the time to measure what it is, has to be some. For what it is worth, the
SERIN2 RX ,BAUD,2500,EMAIL_SET,[WAIT("I/OK")]
has to be the very next line of code after an "AT+Ixx" command is sent. The "I/OK" will be missed if the SERIN command is placed in a sub routine, so the ConnectOne seems pretty fast.

Dave,
I have been reviewing the data sheet for the MiniSocket WiFi module and can't find ansers to following questions. Can you or anyone else on this thread answer them??
1)When using a UART serial interface from the MCU to the MiniSocket to perform asynchronous data transfer, should the TXD pin of the MiniSocket be connected to the RX pin of the MCU? Similarly, should the RXD pin of the MiniSocket be connected to the TX pin of the MCU? I ask this because the Nano WiReach reference design sent to me by ConnectOne has TXD to TX and RXD to Rx, which is contrary with most MCU serial interfaces I have seen.
2)We are not going to use flow control on the serial interface so we are tying the -CTS and ĖRTS pins together. However, we canít determine from the MiniSocket data sheet whether we need to use the handshaking interfaces with DTR and DSR or not when performing asynchronous serial data transfer with the MiniSocket from the MCU. I notice the ConnectOne reference design for the Nano WiReach did show the DTR and DSR interfaces implemented, yet in most asynchronous serial interfaces we have seen with a PIC MCU they are not used. Please clarify??
3) It is my understanding that the MiniSocket (which is a 3.3 v device) is not tolerant to 5v logic signals. Our application is all 5v circuits. Any suggestions on how to convert the 5v logic of the MCU to 3.3v logic for the MiniSocket with minimum hardware....our board is already very densely populated and can't afford a lot of additional components.

Really appreciate any comments/answers to these questions.

John

I'm the other Dave but I'll give you my responses to your questions, anyway.

1. Cross-connect them.

2. The Mini Socket iWiFi datasheet explicitly says to connect CTS/RTS if they are not used but says nothing about DTR/DSR so I don't think you need to connect them but you probably should ask this of Connect One Support.

3. I dropped my intent to make the shield work with 5V and 3.3V because it was just to complicated with all the SPI lines on the other modules. However, with the Mini Socket iWiFi, we are only dealing with two inputs and one output. The way I prefer to handle this is with a transistor and two resistors for each line. You can see example circuits in FIG 15 of AN213 (http://www.zbasic.net/appNotes/AN213.pdf).

What Dave said...
I will add..
When ConnectOne says TXD to TX they are meaning cross over.

If I were you I would make a point to start designing things for 3.3... But in the mean time
here are more possible solutions, or the same ?

I should have mentioned that the Mini Socket iWiFi datasheet says for RXD...
Input - Host Data Receive – Asynchronous serial data received from host.anf for TXD...
Output - Host Data Send – Asynchronous serial data sent to host.

What Dave said...

Thanks for the URL to the Tips file. The only reason I am still using 5.0 volts for the MCU is I am using one of the GPIO pins to power on and off a SRF02 Ultrasonic Ranger, which only operates on 5.0v. I am using two LDO regulators, one for 9v to 5.0 v to power the MCU (and the SRF02), and one further downstream for 5.0v to 3.3v to power the ConnectOne WiFi module.

Thanks, Dave. I also got a Tech Support input from OneConnect saying to connect TXD to MCU's RX and RXD to MCU's Tx, -DTR to ground, -DSR unconnected, and -CTS connected to -RTS. So this clarifies the serial interface requirements for their MiniSocket WiFi module with a PIC MCU.

Other Dave,
I appreciate your referral to this app note...it has a lot of good ideas in it. However, for the level shifting I have to do between the 5V logic on the PIC MCU and the 3.3v logic on the MiniSocket iWiFi module, I am going to give the Sparkfun device a try (see http://www.sparkfun.com/products/8745 ). It is low cost and gives me enough channels to handle the problem. Have you or anyone had any experience with it?

dhouston
- 23rd June 2011, 23:44
Have you or anyone had any experience with it?Yes, I've used it when breadboarding. In fact, I meant to include it in my post but could not find it with a quick search at Spark Fun. (I lost a network drive a few months back which had a lot of my notes, etc. and most of my toys are still in storage after a lengthy hospitalization last year.) It should work fine here.

Also, either the Tips file referenced by mackrackit or a similar one from Microchip (I think.) has tips on getting 5V from 3.3V. For example, if you're using a MAX232 or similar line driver, you can steal 10-12V from it. Of course, it depends on the current needs of your 5V device.

i am waiting for delivery of Nano Lan Reach
http://www.connectone.com/media/upload/Nano_LAN_Reach_PB_01.pdf
but i am not clear as to if i use one of your shelds as below

http://davehouston.org/Arduino.htm (http://davehouston.org/Arduino.htm)
just a few questions
i would be using this with a pic18f452 running at 5v and i know the data sheets for the nano runs at 3v3
if i do supply if it 3v3 do i need to to anything to the Tx/Rx lines or do they have to be 3v3 as well.
On you board is this already taken care of

Regards

isaac

dhouston
- 19th August 2011, 15:04
Yes, if you run the PIC at 5V and the ConnectOne module at 3.3V you will need to do level conversion in both directions.

My shields have been delayed. I had a bout of atrial fibrillation resulting in a brief (4 day) hospitalization but some not so brief medical bills which have blown holes in my budget. All my projects have been set aside for the time being.

The Spark Fun level shifter mentioned above should do what you need. (The AN213 link also shows a few different methods.) You need to deal with TX, RX & RESET. Outputs from the module (TX) need to be shifted up to 5V for input to the PIC, inputs to the module (RX, RESET) need to be shifted down to 3.3V.

Speedy recovery, take it easy in meantime.

I'm fine. I've had Congestive Heart Failure for about 9 years and all is under control by medication. My primary care doc even commented that I have the vital signs of a 20 year old (seems a shame to waste them on a 70 year old). And, tests in the hospital confirmed that my heart is still normal in size and pumping efficiency (ejection fraction) with no water around it.

I just got caught in a couple of bureaucratic snafus not of my own making. I get my meds from the Veterans Administration. I was moving and the VA refused to accept my change of address over the phone, telling me I had to come, in person, with a piece of mail in-hand that I received at the new address. Simultaneously, my cardiologist for the past 9 years (outside the VA) was forced to close his practice by a non-compete lawsuit brought by the very hospital I ended up in which had recently bought the group practice he had been a member of but chose to leave after the sale. I could not reach him to get a prescription so I ran out of two critical meds which regulate BP and pulse rate. I'm back on my medication and even the VA accepted my new address with no further red tape so my supply is assured for awhile.

I just need to clear all the hospital/doctor bills before spending anything on toys.

But, thanks for the good wishes.

Mackrackit, I know your ConnectOne example code is for a Nano Socket iWiFi module configurtion, whereas I am working with a iWiFi MiniSocket module, but I am trying to interpret some of your code to help me figure out how to program my 18F4550 as the embedded host for the MiniSocket. Without your schematic I am confused as to what connections on the iWiFi module are used with the PortC.4 and PORTC.3 connections on the MCU. Could you please post a schematic to help understand the purpose of the different connections between your 16F873A/iWifi module?

Am also confused by some of your code:
Are you using the sequential HIGH and then LOW statements for PORTC.4 to perform somekind of reset of the iWiFi module?
When you use the SEROUT2 statements with PORTC.3, what are you doing when you send ["iChipO OK"] and ["TEST_",DEC3 CNT, 13, 10]?
I also don't understand the purpose of the DIP subroutine??

Can you please explain these statements to me?

mackrackit
- 17th September 2011, 07:08
The DIP routine is for parsing the address that the router assigned to the iChip.

When you use the SEROUT2 statements with PORTC.3, what are you doing when you send ["iChipO OK"] and ["TEST_",DEC3 CNT, 13, 10]?
PORTC.3 goes straight to a terminal for debugging. ["iChipO OK"] is what the iChip returns after a successful operation, I would pass that to a terminal to see if things were working. The code counts to 60 before an email is sent, ["TEST_",DEC3 CNT, 13, 10] is to see what the count is.

HIGH PORTC.4 :PAUSE 250: LOW PORTC.4: PAUSE 500
' Is a crude "heart beat" to see if the MCU is running.


Below is pretty much the same code but for a 18F4550 along with the hookup.
I know, I should use more comments...

Dave, I have adapted your 18F4550 code you included in your above post into a version that uses my schematic and an 18F2550. I have a protoboard configured to my schematic with the MiniSocket mounted on it. I have studied the AT+ Programmers Manual and I believe I understand all the coding and have it correct, but it wouldn't work. The only way I have to trouble shoot this is to embed WRITE to EEPROM statements at incremental locations to isolate where the problems are. I have discovered that in two places the code will not execute beyond certain statements even though this code compiles and assembles OK. If you look at my attached code (which is closely adapted from yours) you will see where the embedded WRITE statements bracket two statements that don't execute. One is a PAUSE 2000 statement that for the life of me I don't understand why it won't execute when uncommented. Can you see why?
The other is obviously telling me that the MiniSocket module is not resonding to the AT+I message and is therefore going to the BROKE label, which tells me that either the MiniSocket module is dead or my board level serial interface is not wired correctly.
I am hoping you might help me trouble shoot this by looking at this code and my attached interface and tell me where I have gone wrong. Would GREATLY appreciate it!

Thanks, Dave. I implemented all of your suggested changes to my 18F2550 adaptation of your example code and the MiniSocket module still doesn't connect to my wireless router/PC. I also tried to use the iChip Config Utility to setup and test the module, but discovered you have to have a serial interace that connects directly to the WiFi module to use it... which I don't have on my PCB implementation. So I looked for another way to setup and test my MiniSocket module and discovered in the Programmers Manual the Easy Configuration method (pg 142 of Programmer's Manual). Per that method, I programmed the MCU to send an AT+iFD command to the module to reset it to Factory Default settings, which will supposedly search for and link up with any AD-HOC AP in range so that you can use this method to get your PC connected to the module to setup the desired configuration for your application. What I discovered leads me to believe that my particular MiniSocket module is a bad one. Take a look at this code and the embedded and commented WRITE EEPROM test and please tell me if you concur with that conclusion.

I don't see any reason for it not to be, but are you able to verify the PIC is actually running at 48Mhz? It seems there can only be 3 reasons to get stuck on a pause: Just taking forever because the clock is wrong, PIC is resetting - WDT maybe? or something is corroupting system variables causing PAUSE to mess up. I don't think it's the last option, no interrupts shown so what else could corrupt it? WDT and MCLR are both turned off. so that seems like it takes option 2 out. Leaves us to clock. The configs look correct, Maybe the crystal is not working/connected/...

Delay of this reply was due to me having to get a new ConnectOne iWiFi Mini Socket Module. I fried the other one.
Also spent time while waiting for new module to get the application code working to requirements up to integration of the iWiFi. My application works perfectly up to the point of integration of the module, which I got yesterday. Spent today trying to get it to work with my application. Here is how my applications works.
1) My application receives a periodic RBC_INT interrupt from the Alarm1 (_INTA) signal sent from a DS1337 RTC.
2) Upon receipt of the interrupt the service routine measures a temperature and depending on the temperature initiates an email via iWiFi.
Everything is working up to here. I hope you guys will help me figure out why the iWiFi and email process isn't working. If you need to see the full schematic of the application it is in a post I made in the Schematic forum regarding a question I had on Oring the backup battery with the Vcc supply for the RTC.

I adapted Dave's ConnectOne example code by breaking it into a set of subroutines to integrate the iWiFi function into my application. My appliction is running on a 16F886 MCU that has a serial interface to the module via a SparkFun serial level converter (MCU is at 5 v....module is at 3.2v). I have double checked the pin/trace interfaces on the PCB and I think they are correct. I will list the subroutines and explain how I intended the process to work below. You will notice I use a lot of WRITE statements to EEPROM for post run evaluation/testing and also a lot of RED and GREEN LED blinking codes for run-time testing. I have annotated each write statement as to whether the code works to that point or not.

Here is the routine called by the interrupt service handler to initiate the Email process...every thing works up to here:

Can you see anything in this that would cause failure other than a broken module? I can't believe that this brand new module is broken. I took extra precautions with it after breaking the previous one. Used static sensitive protection measures and never exposed it to wrong voltage. Please take a look and give me your observations and recommendations. Your help is GREATLY appreciated!

I am not familiar with Sparkfun stuff, that module converts 5 to 3? Why not just run the whole thing from a 3 volt supply and be done with it?

Is your router set for DCHP? Does it see a new device?

I have always used the ConnectOne software to set the passkey and baud rate.

When I get back to the shop I will look at this closer.

My application is also using a SRF02 ultrasonic ranger sensor as controlled by my 16F886 MCU. The SRF02 will only work on 5v so I made the choice of running the MCU also at 5v and then I had to use the Sparkfun level converter between it and the ConnectOne iWiFi module.

I will double check my router setting for DCHP.

What code are you referring to from ConnectOne to set the passkey and baud rate? Can you share or point me to it with a URL?

I really appreciate your looking at my code.

iChipConfig utility

I have used it on win7, but I recommend setting a restore point before installation... just in case.
You will need a MAX232 or equivalent to connect the device to a PC terminal.

Can you link to the sparkfun part?

Do you have a URL link that will get me to where I can download the iChipConfig utilility and its user manual?

I will have to use it on a Windows XP lapto. My application PCB doesn't have a serial interface to it that I can use to connect to PC terminal. Does that mean I can't use iChipConfig utility?

Here is a URL to the SparkFun level converter. http://www.sparkfun.com/products/8745

Dave, I began to wonder if in my process of converting your ConnectOne example code to my 16F886 MCU and my parsing of the code into subroutines that I could call from my application might have done something that screwed up its ability to communicate with the iChip module. So I went back to your original example code which is a lot simpler and modified it slightly so it is supposedly compatible with 16F886, without parsing into subroutines. Below is the resulting code where I have annotated where it stops and won't execute any further. Still looks like I can't get communication with the iChip. Would appreciate you trying it to see if you can get it to communicate with your module.

I also tried using the AT+iFD command to reset the iChip to Factory Defaults, in hopes that it would connect.....I did this because of this quote in the iChip WiFi Configuration Manual which says " Assuming all WiFi related parameters are cleared to their default value, as is the case after a Factory-Defaults setting (AT+iFD), iChip will attempt to associate and connect to the closest available Access Point (AP) that does not have any security configured. " I used this statement to try to do this and it won't even compile as if there is a syntax error: SEROUT2 TX,6 [ "AT+iFD",$d ,$a ] 'Set iChip to Factory Defaults
I don't see anything wrong with this. Any ideas why this won't compile?

I used this statement to try to do this and it won't even compile as if there is a syntax error: SEROUT2 TX,6 [ "AT+iFD",$d ,$a ] 'Set iChip to Factory Defaults
I don't see anything wrong with this. Any ideas why this won't compile?

I at least figured out why this statement wouldn't compile....I forgot to put a comma after the SEROUT2 TX,6 . However, after fixing this and compiling/running it, the factory defaults didn't seem to happen.

I may have found part of the problem. I have placed a voltmeter on the pin that is RX going into the iWiFi and it stays at a constant 3.3 volts throughout this program...no fluctuations indicating any serial transmission. Also put it on the TX pin comming out of my MCU...also constant. This tells me that the serial interface from the MCU is not working. That would mean that the AT+iFD message never got to the module, hence no Factory Defaults. However, I don't know why or how to fix it. Any ideas?

jellis00
- 11th October 2011, 05:14
I changed all the SEROUT2 TX statements in the code to mode 396 to lower the baud rate to 2400 to see if this made the serial interface work. Still doesn't appear to work. BAFFLED!!
Is there any way to tell whether the asynchronous serial interface on a PIC chip that is using PortC.6 and PortC.7 is working?? I don't have an external serial interface to my PCB to use to see if it is working with a PC terminal or I would. I have the TX and RX pins hooked up only internally to the iChip module.

Post #32 has the link to the config utility. You will need a serial interface to your PC to use it along with a MAX232. A USB to serial adapter works fine.

A USB to serial adapter will also let you test you TX, also will help in debugging.

Hang in there, we will get this figured out.

Just received the below email for ConnectOne tech support confirming what you said about Config utility, so looks like the option is out for me since I don't have an external serial interface on my board.

From what I know now, my problem is really getting the PIC to establish serial communications on my board with my code to the iChip. Once that is done I should be able to use the http:// approach he mentions in the email to setup the iChip configuration. So if you ca help me figure out why the PIC isn't executing the serial interface, that will be the big step.
Regards, John

Here is their email:
Hi John,

According to our R&D, the LAN to WiFi Wizard is not operational and should not be used (it should have been removed from the s/w).

To configure the unit either use the FULL CONFIGURATION tool in the iChipConfig or manually type in AT+I commands using the “Dumb terminal”.
Once the unit is configured, it will save the parameters in non volatile memory.
You will need to power down the unit for the parameters to take effect.

Once you’ve setup the module for the AP you want to connect to and enabled the internal web server, you can than access directly the ichip web configuration page via http://x.x.x.x/ichip

All the information you need for setting up the module is available in the documentation I previously sent you.

Can you solder a couple of wire onto your board?a

I think I know where you are going with this, Dave. Are you implying that if I solder 3 individual wires to the pins on my PCB that are TX, RX and GND and then connect those three wires to a DB-9 connector, I can jurry-rig a serial interface to my PCB?

I could do this if that is what you are implying, but I also have the problem that none of our computers have a serial interface on them....they are all newer computers and it seems that only older computers have RS-232. I supposed we could try to use a USB to RS-232 converter cable, but we have had very bad experience in trying to use those...they typically don't work well with serial applications.

Does this code actually work with one of your ConnectOne MiniSockets?
I will try this with mine. If it works with yours and not with mine, this may be a way I can verify whether my module has gone bad or not...which is unforunately one of my increasing suspicions.
John

mackrackit

The code was tested on a ConnectOne Nano Socket. Same chipset as far as I know.

Yup, I am implying bugging in a DB9.

I used one of these (http://www.tripplite.com/en/products/model.cfm?txtModelID=2430&gclid=CI3lzfmj5KsCFQNggwodKg9BUg) while debugging the above code on a win7 netbook. :eek: But I agree, the converters are not good for everything and I have brands that do not work at all.

Or you could get a LCD with a serial back-pack to see what is going on. Either way, it will sure make debugging faster.

It may take a minute or two to get a connection and "blink".


I modified your proven code you inserted above very slightly per below. Because my PCB has the _RES_PD and MSEL interfaces connected to MCU pins for control of the module, I had to insert the "Initialize" statements for those interfaces per programmers manual to supposedly have module in normal AT+i ops for the internal serial interface. I also inserted some WRITE to EEPROM statements with comments and some LED blinking to assist my troubleshooting.

As you can see from the comments, I never get the first I/OK acknowledgment from the module, which tells me that the internal serial interface from my MCU to the module is not working.

Next step I guess is to solder 3 wires to my PCB to provision a temporary serial interface to my PC to see if Serial interface is working from MCU. Any other suggestions?

The only pins used for normal operation are the GND, VDD, RXD0, and TXD0. All others are left floating.

You are keeping things in reset by playing with the other pins.

jellis00

I understand your point, Dave, but I already built the PCB with hookups to MSEL and _RES_PD from the MCU so have to make them work in the setup.

This code works! The fix was to set TRISC so that _RES_PD and MSEL were declared as outputs. When this worked I was able to read the EEPROM to see what the IP was for the iChip website that it established and then to got to it via http://xx.xx.x.xxx/ichip and set the parameters I wanted.
Now on to figure out how to integrate this working code into my application so I can use the iWiFi module to send an email via its connection with my wireless router to the internet.
Thanks for your help, Dave. I hope this attached code will show others who visit this thread how to setup a iWiFi MiniSocket module to set its parameters without having to use the config utility.

Glad you got it working!!!

But,
TRISC.1 = 0 ' Make pin output for MSEL
TRISC.2 = 0 ' Make pin output for _RES_PD
Would/should not have made a difference because the HIGH/LOW commands do that in the background.

Must have been another change...

I thought it was working...and it is to a point. However I am seeing an anomaly I can't understand. I hope you can help me figure this out.

I am programming my application with the below code using a PICKIT2. I have the PICKIT2 set to "VDD Target" so that the PICKIT2 is not providing power...my application has its own power.
The programming of the device is normal and it starts working and executes the program normally as long as the PICKIT2 is still connected (but not providing power).

However, when I disconnect the PICKIT2 and power down my application and then reapply the application's power, the code is obviously stopping execution at the point in the code where the AT+i coommand is given to set auto-baud at 9600 baud. I know this from the WRITE 4,4 statement not appearing in EEPROM after the test run and the LED_RED not blinking. However, when I then reconnect the PICKIT2 and load the PICKIT2 software with its screen, my application then works normally and executes the complete program with the LED_RED blinking as a heart beat during the BOOT loop.

It is almost like the iWiFi module isn't getting power when the PICKIT2 is disconnected and therefore the AT+iBDRA fails...but it is getting power...I checked with a voltmeter.
I am stumped and can't go any further in integrating this code with my overall application until I resolve this anomaly.

Do you or anyone have any ideas why the iWiFi module would act this way with this code and this scenario?? At least I was able to use this code when it worked while PICKIT2 was connected to identify the IP address, log into the iChip web server from my PC via the wireless route,r and set parameters on the iChip.

Does the PIC run without the PicKit2?
Do a blinky to verify.

The Sparkfun device looks like it requires 5 and 3 volts.
Do you have both? Do they share a ground, VSS ?

Do you have capacitors near the PIC across VDD and VSS?

Did you change the backup battery problem?

Does the PIC run without the PicKit2?
Do a blinky to verify.
I created a set of code that is the same as above post down through the _RES_PD and MSEL initialization followed only by a mainloop that blinks the LED. I did this so that all the setup code I was using was still the same in this test. This blinky code works whether the PICKIT2 is connected or not, so that didn't ID the problem.

The Sparkfun device looks like it requires 5 and 3 volts.
Do you have both? Yes. Actually I have the iWiFi module running on 3.32 volts which is within its required Vdd range, so the lov voltage side of the Sparkfun converter is at 3.32v.

Do they share a ground, VSS ? Yes, I created a large ground plane layer on the top layer of my PCB right below the iWiFi module's outline where it is mounted to the PCB and this ground plane is shared with the level converter, the PIC and the rest of the PCB circuit.


Do you have capacitors near the PIC across VDD and VSS? Yes, I have a 10uf tantalum and a 0.1uf ceramic connected near Vdd on the PIC to the Vss.


Did you change the backup battery problem? Yes, after I cut the traces to the pull-ups and greenwired them to Vcc I then replaced the backup battery and the clock is running fine and maintaining time.

These were all good questions and I appreciate you making me think through this. The bad news is that the code still quits running when the PICKIT2 is disconnected. However the good news is that I am now sending and receiving an email from the ichip (but only when the PICKIT2 is connected). Still trying to figure out the AT+i commands and right sequence of WAITs to only send one email when I want to. At this time for some reason it is sending two emails one minute apart repeated every 8 minutes. I thought I had the timing in this code set to only send one every 5 minutes and don't see where this is causing the repeats at the wrong interval. I only want it to send one every 5 minutes. I don't think I have the WAIT statements for I/OK, I/DONE, and I/ERROR correct and the timeouts to the EMAIL label may be causing repeated emails. Here is the EMAIL routine code I am using....any suggestions?

To have accurate timing you will need to interrupt base the routine. You can use the RTC for that.

jellis00
- 22nd October 2011, 05:47
Dave, I am already using a DS1337 RTC in my applicaton with intention of using an interrupt from it on periodic basis to take a temperature reading and to initiate emails via the wireless module per the code I am currently trouble shooting. You can see the schematic of all this in an email I sent to Darrel Taylor which I copied you on in which I enlisted his help to find out why it is only working when a PICKIT2 is plugged in. I also included you on an email to ConnectOne techsupport and one that was direct to you regarding how you terminated the _RES_PD and MSEL connections in your application. Did you get them??

mackrackit
- 22nd October 2011, 06:11
I just saw them, got two.

I do not have the RES_PD or MSEL pins connected to anything, they are floating.

Cut some more traces.
Or if all else fails, skip the sparkfun part and test with the whole system running on ~3 volts.

Ain't prototyping fun :)

jellis00
- 11th November 2011, 01:34
Dave, I finally got it all working...or I should say almost all. Still troubleshooting one statement I want to add to the FTP process that is posting the wrong HH:MM values used from the RTC...for which I will describe and ask for help at end of this posting..

First of all, I made what I think are some good changes to the approach which I will share below for benefit of anyone else monitoring this thread that is trying to use the ConnectOne iWiFi MiniSocket module. I broke a lot of your sample code into some callable subroutines which I will list and explain below. I am posting all this code because I discovered that the ConnectOne programmers manual for the MiniSocket doesn't have any examples so it is somewhat difficult to get the syntax just right. Since these routines are tested and work it should save others from having this problem. Although I should say that the TechSupport people at ConnectOne have been very helpful and also say they are going to add examples to each command reference in their next publish of the programmers manual for the very reason I pointed out to them.

You will see a lot of WRITE to EEPROM statements embedded in this code which you can comment out or ignore...I use them to debug the AT+i command sequences so I know where the hangups are in the code by reading the EEPROM of the MCU after each run of the code when programming the MiniSocket module. I also have embedded a lot of variable duration, blinking LED statements to make use of a GREEN/ RED LED on my board to help see what is happening when the code is running.

From your mainloop when you want to use the MiniSocket module you first need to call this subroutine (BOOT) to initialize the module. You will have to substitue your own router SSID name in the iWLSI statement.


BOOT: 'Subroutine for setting up ConnectOne MiniSocket iWiFi module
' Blink Green LED 2x short at start of BOOT routine...for test only
FOR I = 0 TO 1
HIGH LED_GRN
PAUSE 250
LOW LED_GRN
PAUSE 250
NEXT
PAUSE 1000 'Initialize iWiFi MiniSocket Module
HIGH _RES_PD ' Set high for normal ops
PAUSE 500 ' Delay to stabilize if coming out of power up mode
WRITE 48,2 'EEPROM test to see if program executes to here..it does.

'SERIN2 RX ,84,2500,BOOT,[WAIT("I/OK")]
PAUSE 100
WRITE 50,4 'EEPROM test to see if program executes to here..it does!
SEROUT2 TX,84,["AT+iWLSI=EllisOfficeNetwork",$d,$a]' SET SSID WE ARE LOOKING FOR
SERIN2 RX ,84,2500,BOOT,[WAIT("I/OK")] '
PAUSE 100
' Commented out until WPA setup on wireless router
'SEROUT2 TX,84,["AT+iWLPP=passphrase",$d,$a] ' SET PASS-PHRASE
'SERIN2 RX ,84,2500,BOOT,[WAIT("I/OK")]
'PAUSE 100
WRITE 51,5 'EEPROM test to see if program executes to here..it does!
SEROUT2 TX ,84, [ "AT+iIPA?" , $d , $a ] 'Report the current IP address
SERIN2 RX ,84, 2500 ,BOOT , [ DEC ADR[0] , DEC ADR[1] , DEC ADR[2] , DEC ADR[3] ] 'Store IP in array
WRITE 52,6 'EEPROM test to see if program executes to here..it does!
GOSUB DIP ' If IP address is empty, report not connected
PAUSE 1000
WRITE 32,ADR[0] ' Write the IP to EEPROM for post run identify...for test only
WRITE 33,ADR[1]
WRITE 34,ADR[2]
WRITE 35,ADR[3]
WRITE 53,7 'EEPROM test to see if program executes to here..it does!
RETURN


For completeness I will also list a couple of other routines that are called by BOOT (BROKE and DIP):


BROKE: ' Executes when iChip not working...blinks LED_RED
WRITE 5, "B" 'Record in EEPROM as test if Broke!
' Blink LED_RED 3X long to indicate iChip not working
FOR I = 0 TO 2
TOGGLE LED_RED
PAUSE 1000
TOGGLE LED_RED
PAUSE 1000
NEXT
PAUSE 2000
GOTO BOOT




DIP: ' Check whether IP is valid, blink LED_RED if not
'===
IF (!ADR[0]) AND (!ADR[1]) AND (!ADR[2]) AND (!ADR[3]) THEN
' Blink LED_RED 4X short to indicate iChip not working
FOR I = 0 TO 3
TOGGLE LED_RED
PAUSE 250
TOGGLE LED_RED
PAUSE 250
NEXT
PAUSE 2000
ENDIF
PAUSE 1000
RETURN


Then after the BOOT routine has been executed you can call the EMAIL routine listed below to send an email to wherever you want (by changing some of the permanent AT+i parameters you must have previously programmed per the inital comments in the start of the EMAIL routine):


Email: ' Sends email via ConnectOne iWifi MiniSocket module

' Blink Green LED 1x long at start of Email routine
TOGGLE LED_GRN
PAUSE 1000
TOGGLE LED_GRN
PAUSE 2000
WRITE 54,8 'EEPROM test to see if program executes to here..it does!
' Put code here to email low temperature warning via WiFi
SEROUT2 TX,84,["AT+iEMA:",$d,$a] 'Defines a plain text e-mail body

GOSUB Blink_GRN ' Short blink LED_GRN 2x after email sent
GOSUB Blink_GRN
PAUSE 1000

' Blink Green LED 2x long after email sent
FOR I = 0 TO 1
TOGGLE LED_GRN
PAUSE 1000
TOGGLE LED_GRN
PAUSE 1000
NEXT
RETURN


Alternatively you can call the FTP routine to FTP data to a website of your choice for which you will have to modify the domain, username and password in the iFOPN statement, the directory name (iChip) in the iFCWD statement, and the file name (include-3.txt) in the iFSTO statement. In my application I have a folder on the website named "iChip" which contains a text file named "include-3.txt" to which this code writes the information in the iFSND statements. The website uses a PHP script to automatically update the web page by reading and displaying the text file every 2 minutes so it dynamically keeps up with the updates that may be coming from the MiniSocket module at rate faster than 2 minutes. If anyone wants this PHP script for use on their website, send me a PM.

I hope the above routines will help people that are using the ConnectOne MiniSocket avoid the learning curve I had to go thru.

Now for a request for help to solve a remaining problem I am trying to solve in using the MiniSocket with PICBASICPro.
Since my application has an embedded RTC, I want to include in the FTP routine a sequence that will send a message as a time stamp so that whoever logs into the website can see when the data was posted. To do this I am trying to use the following added iFSND statements to append a time stamp to the rest of the posted data:

My problem centers around the statement: SEROUT2 TX,84,["AT+iFSND:000,5:",HEX2 hr,":",HEX2 MINs,$d,$a]:PAUSE 100
For some reason the displayed values in the website always show up as constant 4:32 in all FTP postings rather than as the actual HH:MM values from the RTC at the time of the posting. Can anyone tell me why this is happening? I have spent a couple of days trying to figure this out with no success and any help would be appreciated.

Since these routines are tested and work it should save others from having this problem.

CORRECTION! I discovered that running the above routines as callables from a mainloop will only execute correctly on the first loop and will quit after that.
This was due to a simple syntax error in one of the statements in the FTP subroutine. Therefore, replace the above posted FTP routine with this one that has been corrected and the routines will continue to work no matter how many times they are called:

What was your Aha moment that finally got things working?


I hope the above routines will help people that are using the ConnectOne MiniSocket avoid the learning curve I had to go thru.
I do not see what you did different from what you were working with at the beginning?

RTC-FTP
I have to ask, are you certain the RTC is running.

jellis00
- 11th November 2011, 20:12
The Aha moment came when I finally purchased an EVB for the MiniSocket that allowed me to use the config utility to pre-set the parameters in my iChip and to interactively test different sequences of AT+i commands, which also helped me converge on the correct syntax for the AT+i commands. Once I did this, it helped transition the results and my learning curve to my PBP code version of the AT+i commands.

The main thing I did different than Macrackit's example code is break things into callable subroutines so that the user can decide where and in what sequence in the mainloop to make things happen with the MiniSocket. Since the AT+i code will stop anywhere it fails and therefore stop further execution of the main PBP program, this gives more flexibility to the user on how to use the different features of the MiniSocket rather than a complete, single, in-line code set like Mackrackit's example which will fail wherever an AT+i command fails. For example, breaking the Email process away from the FTP process as separate callable routines very much accelerated my troubleshooting process and seems to increase the reliability of the functional performance of the main program.

Annother thing I did different was to take advantadge of the fact that most of the EMAIL setup AT+i parameters can be pre-set as permanent parameters stored in FLASH on the iChip. As long as you are always going to send the EMAILs to the same place, as my application does, this eliminates the need of having to list these as PBP statements in you program and executing them everytime you send an email, as Mackrackit is doing in his example code....this saves MCU program memory and reduces execution time of the EMAIL routine.

Good question re: RTC-FTP. I know the RTC is running during most of the program because of the embedded statements that WRITE the HH:MM to EEPROM. However, I haven't tested to make sure it is still running and hasn't stopped for some reason when the FTP subroutine starts. I will do that...Thanks! I am also going to try changing the time statement from HEX2 hr and HEX2 MINs to DEC2 hr and DEC2 MINs to see if that displays the correct time on the web page after the FTP. I know using HEX2 is the right way to display time on LCD, but not sure whether it should stay in HEX format via the FTP process to web page or not.

I notice you attempted to send me a PM this morning and my PM mailbox was full and rejected it. I have cleaned up my PM mail box, so send it again.
Thanks for all your help and advice. /s/ John Ellis

... i want to use the WizFi210-EVB module sir.its more alike in connectone sir..tnxThe WizFi210-EVB bears no resemblance to the Connect One module. It has a DB-9 connector for the serial connection and uses RS232 levels and polarity. You'll just confuse yourself looking at Dave's schematic. Refer, instead, to the WizFi210-EVB schematic (http://www.wiznet.co.kr/Sub_Modules/en/product/Product_Detail.asp?cate1=5&cate2=43&cate3=0&pid=1133#tab) and their other documentation.

i was just confuse of what PIC should i use to interface the WizFi210-EVB sir...i'm a beginner sir so any suggestion of wat PIC should i use?...tnx...i want to design a PIR sensor like john design nw but i use WizFi210-EVB instead of connectone ant PIR instead of ultrasonic.and iwant to interface to PC unit with an application of Visual Basic as my GUI...i want to monitor my sensor through wireless..

The WizFi210-EVB is designed to connect to a PC via its DB-9 connector. How do you plan to connect the PIR sensor? It will get awfully expensive if you plan to use another WizFi210-EVB to provide it with WiFi.

Does your LAN have a WiFi router? If so, you only need a WiFi interface for the sensor but the WizFi210-EVB is both costly and poorly suited for that as you would have to un-covert the RS232 levels/polarity (or use Debug/DebugIn). You would be better off designing your own PCB for the WizFi210 plus whatever PIC you wish to use which really depends on what else you need the PIC to do.

The WizFi210/220 have several pins (ADC, DIO) that you can probably use to connect directly with the sensor w/o need of a PIC. Download the documentation from the page I referenced earlier in the thread. One of the application notes appears to show getting data from the module using HTTP although it does not provide sufficient detail to be sure. You probably should be communicating with WizNET rather than posting questions here.

I have designed a Zarduino (http://davehouston.org/WizNET.htm)TM Shield for the WizFi210/220 or Wiz105SR with prototype PCBs being made right now. Once I have the PCBs and can test them, I'll try to figure out the HTTP app note and post here. But, that's likely to be 4-5 weeks away.

Not sure whether you are asking me for schematic or from mackrackit.
As mackrackit says in one of his posts, we have both posted schematics. However, the previous one I posted had some errors in how to connect the ConnectOne iWiFi MiniSocket module, which I discovered the hard way in my PCB and had to re-do the wiring on the PCB. Therefore, if you want this updated schematic that shows how to wire the MiniSocket and how to use a SparkFun level converter module in the interface between the PIC MCU and the MiniSocket, here it is attached.

For your info, kenruizal, I agree with Dave on his statement above. The WizFi210 is expensive and difficult to program. I did a thorough evaluation on the available WiFi modules and ended up selecting the ConnectOne iWiFi MiniSocket Module. I recommend you use a ConnectOne iWiFi MiniSocket Module on a PCB interfaced to a PIC chip via a SparkFun level converter like I did (if you have to use 5V on the PIC for interface to your PIR sensor....if not you can run everything on 3v and eliminate the SparkFun level converter...see my schematic in above post). It is easy to program in PBP to command the MiniSocket module with its AT+i commands. It can be purchased for ~$58 for plugin to your PCB via a 2x6 female header. Then once you have debugged the code while running on your PCB you can further reduce the cost by using ConnectOne's reference design and do a 2nd generation PCB with all the iWiFi module components mounted directly on the PCB as surface mount devices.

I can help you with a couple of subroutines I developed that are tested and working with the MiniSocket. These subroutines connect to an external website via the internet and post data to it, as well as another one to send emails. You can also program it as a TCP listening socket and command it from the internet side. If you need help on this, start a new thread and point me to it via a Personal Message and I will help you get it working.

For your info, kenruizal, I agree with Dave on his statement above. The WizFi210 is expensive and difficult to program.I wouldn't go that far. The WizFi210 itself is inexpensive, retailing for $30US but the Evaluation Board which the OP proposed using costs $110US so is rather expensive. For setting the configuration, the WizFi210 also uses an AT command set similar to what ConnectOne uses so, while it lacks a few protocols (email, network time), programming looks fairly simple. It has two ADC pins and several DIO pins as well as multiple communications methods (Serial, SPI, I2C, etc.). It's main drawback is the need for a custom designed PCB.

That it has ADC functions is intriguing. It really makes no sense to have them if you can only read them with a microcontroller since you could likely do that more easily with the microcontroller ADC channels. There is an app note (HTTP Data Transfer) that appears to show how to read a sensor over HTTP but, like most of their documentation, is sparse and difficult to understand.

The internal 8MHz oscillator is fine for this.
I use a PicKit2 to load the hex file onto the 4550.

I can not find my schematic but...

Using the Nano Socket IWifi.

Header J8 iWifi pin 8 connect to pin 12 max232
Header J8 iWifi pin 9 connect to pin 11 max 232

Max232 pin 13 connect to PC DB9 pin 3
Max232 pin 14 connect to PC DB9 pin 2

And the grounds (zero rail) are all common.

Hi,
I just ordered a Connect One SocketLAN, and am doing some background searching for tips on how to hook it up to a PIC project. It looks like the serial pins are the most basic but am a little in the dark about the above conversation. Should I be adding hardware/provisions for a MAX232 circuit to talk to a terminal program too, and if so, how should it connect... to the PIC, or to the SocketLAN? I see Macrackit's code examples, but it doesn't tell me anything about how the hardware is connected. This is my first attempt at an ethernet project, and don't want to miss anything critical as I'm mulling over a board layout. I plan to start off with the PIC's serial connection to the SocketLAN for simple emails etc.

Anybody have a simple hookup drawing, or can explain what this terminal connection you're talking about is?

Thanks
