WiFi
Another option is...It lists SMTP among the protocols supported but that is incorrect. It does not support SMTP but is attractively priced for a WiFi to serial adapter.

I did not have that option. I had nearly 100 partially assembled PCBs that were designed for the Tibbo EM202. I used the ZX-40a (ZBasic) as the CPU and, while my board is designed to use a wall transformer (switchmode) supply, the ZX-40a must run at 5V or the software UARTS (full duplex background operation) must be limited to 4800bps. I had to design a 5V to 3.3V adapter board so I could use the nano LanReach, instead of the Tibbo which was discontinued just as I ordered the first batch.Originally Posted by l_gaminde

Lots of PICs run at 3.3v... even the 10F series, go ahead and play...
Look at the electrical spec part of the data sheet and it tells you there how fast the PIC can be run at what voltage. Slower the speed the lower the voltage.
But...
If you need the speed and low voltage go with an 18Fer. For example: I run 18F4550 with an external 4 Mhz resonator at 3.~ volts. Using the PLL option it is cranked up to 48Mhz.
Works great when you need to connect to something like a SD card. The whole system can then run at the 3.~ volts at a speed fast enough to get something done.

EZWebLynx from CCS
Hi,
CCS makes one product called EZWeblynx : http://www.ezweblynx.com
Available as :
1. 5V Rev1 -- PIC18F2685
2. 5V Rev2 -- PIC18F6722
3. 3.3V -- PIC18F67J60
It is programmable simply through HTML. Can take inputs (I/O, serial) can drive LCD/LEDs.
Uses a modified Microchip TCP/IP stack. So possible to develop your own sometimes...
Cheap. $54

Sougata
Thanx for suggestions everyone.
I can grab the ENC28J60 locally, but i'm also interested in the "Connect One" modules too....awaiting order to be processed....
As much as i've read thru tcp/ip stack docs, and several webpages etc, it's still not clear (to me anyway, and i've sat thru Cisco CCNA 1+2) about HOW i get these ethernet modules to work.
Can somebody give me some BASIC pointers or links to 'HOW TO' sites....
A simple checklist of things that need to be done would be VERY handy.
Even the data sheets from various vendors state things like
"by implementing the use of....."
"by simply adding...."
"with the simple addition of......"
but these statements dont ANSWER anything.....
they tell me WHAT needs to be done, but now HOW it's done......
So far, all i seem to find in many forums and sites are comments like "i used this, i used that, i added this, and implementd that" which is really NO HELP to me at all when i actually wanted to know HOW they achieved a working unit.
For starters:
Is the ethernet device pre-programmed ready to use?
what do i do with the microchip tcp/ip stack?
Does it program into the ethernet device? into my code? called from my code using the include statement or something else?
It seems many ethernet modules claim "a simple way to connect any mcu onto the internet" and yet i'm finding it to be the most complex task to achive, what am i missing?
For the people out there who have bought these modules, and already tinkered with them for testing, PLEASE share HOW & WHAT you did to get things up'n'running......
I hope someday i'll look back on this and laugh, I know a challenge is good, but frustratiion isn't welcome....
Sorry if i'm ranting & raving, but sheesh, it shouldn't be this hard????
Thanx in advance,
Marty.
With the ConnectOne modules (and the ENC28J60) you do not need the Microchip stack. You connect using either serial (RS232 TTL) or SPI.
Read the ConnectOne AT+i Programmer's Manual. Basically, you communicate with the nano LanReach using AT commands in the same manner as with a modem using the serial interface. It's very simple.
With the ENC28J60, you are working at a lower level and it is far more complicated.
Stick with ConnectOne.
Thanx for that,
That's just another plus to choose the "Connect One" then ;-)
There were some issues with Mouser being restricted to Export Connect One devices to Australia, although now i'm informed by Connect One the restriction will be lifted in a few days, and i should contact Mouser again to place orders.....
In my initial research i thought ALL ethernet modules were simply controlled with serial/spi commands, but after digging deeper i started finding that wasn't always the case, and some modules required lower level information etc.....something i DIDN'T want to embark on......
Thanx again.
I am looking to save a few lines of data logging text from a PIC to a text file on a PC network.
Are any of the previously mentioned devices capable of this or is a
Delphi/VB program required to receive the data and then save the text lines?
Norm
ConnectOne has been saying that for a few months now so I would not give it a lot of credence. Check the Where To Buy link on the ConnectOne website - they list a number of distributors around the world so you can probably find another source. Mouser is being overly aggressive in (mis)interpreting post-9/11 rules on technology exports.
I have only used one device it was connect1s iChipThanx for suggestions everyone.

it works like a modem giving it ati commands and there are hundreds of commands no stack no nothing!! download there manual and read it, ITs a 3.3 volt device so adapter needed, or run your project on 3.3 volts or you have 10 extra wires.
