Have you done a FOR/NEXT loop yet?

Yes, your good self and Henrik explained FOR/NEXT loop and LOOKUP when I was using a BCD driver to make a seven segment display count up and down from 0-9 and write my name. Seems like ages ago now, it was only February/March this year

So your example adds the value S_TEMP to the stored value ADC_TEMP which is done 20 times, then the ADC_TEMP value is output as OUT_TEMP a 20 cycle average (I hope I've read this right).

Now I'm thinking thermocouple / ADC / Seven segment display.....Another project!

Ah, before I forget, from your ADC/rentron explanation link you posted earlier. The ADC conversion is displayed on a rather nice data logger display, is this logger included in the Microcode studio package the same as the Serial Communicator? Image below:

I sometimes think DT is part machine

The stuff he comes up with is invaluable around here. I am just happy that he shares his hard earned knowledge.

The GUI from Bruce's site I think is written in Visual Basic. Here is something he has to offer.

Do you have a language for the PC that you use? You could make you own.

The same as that. Anyone who gives of their time / knowledge gets my appreciation. Maybe one day I'll be able to help someone out, hey maybe other 'lurker newbies' have been indireclty helped by the Q's I've asked, even the answers I given.

Thanks for that mackrackit.

Well I do swear at it from time to time

I don't think I'm clever enough to make my own data_logger application though. Interestingly, when I was researching rfpic's, several times I came across Visual Basic being used in applications to store transmitted_data. For this project
when the daily count is transmitted from rfpic - pic - to serial communicator it will need to be stored somewhere, so maybe a visual basic application could be the answer.

I have got Microsoft VB 2008 Express Edition on my pc, also Visual C++

If all of that is from VB08 then I would say you have what you need.
Sounds like you will be writing a test terminal soon

**LEDave** · - 11th August 2010, 17:25

Mmm.

How about:

Something like this maybe (a VB example)......?

Code:

Function ReceiveSerialData() As String
    ' Receive strings from a serial port.
    Dim returnStr As String = ""

    Using com1 As IO.Ports.SerialPort = _
            My.Computer.Ports.OpenSerialPort("COM1")
        Do
            Dim Incoming As String = com1.ReadLine()
            If Incoming Is Nothing Then
                Exit Do
            Else
                returnStr &= Incoming & vbCrLf
            End If
        Loop
    End Using

    Return returnStr
End Function

VB 5 was the "in thing" the last time I used it.

So...
Does it work?

**LEDave** · - 11th August 2010, 17:56

So... Does it work?

I don't know. I'm not even sure what application to use, is it a:

1/ Windows Form Application

2/ Class Library

3/ WPF Application

4/ WPF Browser Application

5/ Console Application

I know less about VB than I do PIC_Basic.........(a lot less)

Also the serial port is on a turn of the Century Compaq pc so I'd have to transfer the application over I guess.

Dave

**mackrackit** · - 11th August 2010, 18:35

My guess would be
1/ Windows Form Application

Have you ever tried a serial to USB converter?

PC code... Being that you do not mind a learning curve and not all that familiar with VB, you could start learning Python or something like that. In my opinion there is something to be said about cross platform comparability. Linux, MAC OS, Windows, in the back ground on a server, Droids, broken iPhones...

**LEDave** · - 11th August 2010, 19:47

Being that you do not mind a learning curve and not all that familiar with VB, you could start learning.......

I was just thinking the same thing over tea. It would be really neat to have a complete project that gathers the data, rfpic's it over then stores it in an application / program.

So PYTHON v's VB how similar or which is best / more suited?

Is this the sort of thing, serial to USB?

Here's some good info on VB over at rentron.

Check out the Receiving Data From A Microcontroller and Sending Data To A Microcontroller sections. (but read the others too)

And no, I'm not a machine ...
By definition, a machine does "work".
I'm too busy playing for that.

Well I 'ment that in a good way.

Yup, that is the cable.

So PYTHON v's VB how similar or which is best / more suited?

That is a loaded question. Could start a heated debate...

Not similar at all. There are a few GUI builders for Python but the strange thing is, not all of the GUIs are cross platform. Tk comes with the typical python install, cross platform, but some say it is not the prettiest.

The guy that invented python was/is a C programmer so python looks more like C at first glance.

More suited... ???
VB is pretty much locked to windows, we know that..., but if that does not bother you..
In the end I will say it depends on the person at the keyboard. They will both make reliable code.

I will bet you could have something up and running faster with VB. The link Darrel gave should really speed things up.

**LEDave** · - 11th August 2010, 20:35

That'll be me then.......worryingly

I will bet you could have something up and running faster with VB.

I'll go with VB for the project then.

The link Darrel gave should really speed things up

I think it's only fair to mention that when I look at VB code, I have the same / less understanding than when I lit my first PICBASIC led. That's not to say I won't give it my best shot though.

I'll order up a cable.

Dave

**LEDave** · - 11th August 2010, 23:28

I've ordered the USB-RS cable up.

Not sure how to go about learning VB, so I was thinking of going through the RENTRON rec/send programs line by line and taking notes.

**mackrackit** · - 12th August 2010, 12:03

Make an app with a "button" that when clicked writes "hello world" in a text box.
Then you can move to displaying the serial input in the same Tbox.

And of course read everything Bruce has to offer....

**LEDave** · - 12th August 2010, 18:21

I've now got an App with a text box and a button

All I need now is to figure out how to display 'Hello World' when the button is pressed

This is going to take a while as I've loads of reading to do, so please bear with me. If I get really stuck then I'll have to ask.

Have a nice Weekend everybody.

VB_Dave

**mackrackit** · - 12th August 2010, 20:19

All I need now is to figure out how to display 'Hello World' when the button is pressed

And in color...

**LEDave** · - 12th August 2010, 21:13

A small breakthrough: "Hello World" when the button is pressed.......:

Code:

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        TextBox1.Text = "Hello World"

    End Sub
End Class

I just read this: And in color... ! I'm more of a Henry Ford man myself, color it is then.....!

Dave

**mackrackit** · - 12th August 2010, 21:22

RED Mustangs ??? The new Ford

Might be cool to have numbers and letters a different color..... If you are making your own terminal thing may as well trick it out...

**LEDave** · - 12th August 2010, 23:30

This is my 'attemp' to write the 'H' 'e' of Hello world in different colors in the text box.The 'Button' in the Form when pressed outputs the text 'He'.

Is this remotely close or am I heading North......again

Code:

 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


        Dim First As String
        Dim second As String
        Dim Third As String
        Dim value As Color

        value = Color.Red

        First = "H"

        value = Color.Blue

        second = "e"

        Third = First & second

        TextBox1.Text = Third

    End Sub
End Class

I think I needed to add somehow/somewhere to get the colors to work/change:

Code:

Public Shared ReadOnly Property Red As Color

My brother_in_law used to have a Mustang (V8) I was about 14 when he had it. I'm not sure if I liked the looks or the sound the best

Dave

**mackrackit** · - 13th August 2010, 06:04

Like I said, been a long time since I used VB..

I think you will need to parse the string into an array maybe and then check the elements, I will not even try the syntax. But this might give some clues.

**LEDave** · - 13th August 2010, 15:05

Hi mackrackit,

I think you will need to parse the string into an array maybe and then check the elements

I've heard of all three and never used any of them, so more reading for me tonight.

I suppose an array is an array, if I learn about them for VB the same theory applies to a picbasic array so all part of the learning curve, the same for parse and elements.

Dave

**mackrackit** · - 13th August 2010, 16:41

I would not get hung up on the color thing right now, but of course it is up to you.
Getting the data from the MCU to VB is the important part. Dressing it up can come later.

**LEDave** · - 13th August 2010, 22:21

Hi mackrackit,

Getting the data from the MCU to VB is the important part. Dressing it up can come later.

Indeed, Ill stick with that for now.

As as aside:

Learning to program is similar to learning to play a keyboard in that you want to be able to jump in and create/play something just like the original, however there's a big learning curve to be overcome and there are no short cuts! Wonderful feeling when things start to happen though.

Cheers mackrackit,

That's one serious and impressive interface. I think the thing that really impresses me the most here is the way you guys 'see' the solution in software if that makes sense, very,very impressive.

I'm going to have to play catch up and try and fill some very large gaps in my knowledge base (if I can).

Here's trying.

Dave

**LEDave** · - 18th August 2010, 22:07

I've been installing the software for the USB-serial cable and a warning has come up saying basically that the software hasn't passed Windows logo testing and may destabalize or impair system performance now or in the future.......

Should I ignore and install or head the warning? I've made a system restore point before I started the install.

Or is there another driver that would do the job?

Dave

**mackrackit** · - 18th August 2010, 22:19

I saw this on the amazon link you gave

Bought this cable, and the little CD that came with it clearly assumed a greater level of knowledge than I possessed! I was lost and couldn't install a driver for it. Then I found the link to the seller (Aquarius Computers) and an invitation to contact via a contact form. This was 2.30pm on a Saturday, and by 4pm same day I had a reply pointing me at a site to directly download the driver, which was straightforward to install. Everything working smoothly now.
If you have the same problem (I have XP and using the cable to run an external modem) Google "PL-2303 Software and Drivers" (include the double quotes) and choose the link ending ID=31. There, on the Prolific Technology Inc. site, you will find a file to download called wd_pl2303_v20019v2028.zip. Caters for Win98SE/ME and Win2K/XP/2003.

**LEDave** · - 18th August 2010, 22:32

Hi mackrackit,

On the disc there's a folder called: PL2303 which contains a winxp folder containing: PL2303-DRIVER-INSTALLER.

Is that the one I need / should install?

Dave

**mackrackit** · - 18th August 2010, 22:39

I would get the latest greatest from the manufacture.

What OS are you running?

**LEDave** · - 18th August 2010, 22:47

What OS are you running?

XP.

Shall I go for:

Google "PL-2303 Software and Drivers"?

This one:

That looks good.
You did say a fresh restore point has been made. Are you backed-up?

**LEDave** · - 19th August 2010, 00:10

Dave

**LEDave** · - 19th August 2010, 17:02

Mmm,

Well I installed the driver:

Prolific USB-Serial Com Port (COM3)

However it says:

This device cannot start. (Code 10)

And code 10 from M-SOFT says:

Code 10

If the device has a FailReasonString value in its hardware key, that string is displayed as the error message. The driver or enumerator puts this registry string value there. If there is no FailReasonString in the hardware key, you receive the following error message:
This device cannot start. (Code 10)
Recommended resolutions

Here are some things that you can try to resolve this problem.

Update the driver

In the device Properties dialog box, click the Driver tab, and then click Update Driver to start the Hardware Update Wizard. Follow the instructions to update the driver.

You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor’s Web site.

I've deleted and re-installed it, same outcome and checked for a later driver, same outcome.

What's meant to happen here then mackrackit, is the USB-Serial meant to work through the Serial Communicator or via it's own application?
