USB-1208LS Sample Program doesn't work

[Hammer]

Hi,

I have installed USB-1208LS to Windows10 PC and it is ok when I test it using test mode of instacal.
I have compiled and built the sample program "ULAI01.C" with Visual Studio 2022.
But,when I test it, it doesn't work and outputs the message "USB-1208LS (board 0) does not have analog input channels.".
what should I do?

Best Regards,

Hammer

Hello Hammer,

Attached to this message is a 32-bit C console program that should work with your USB-1208LS. Instead of using the cbAIn function, it uses cbAInScan and acquires the data as a background task. Create a 32-bit C console project with this code and let me know if you still get the no channels error. 

Best regards,

John

Hello John,

Thank you for your help.

I tried to compile your program. But, Visual Studio 2022 outputs the message "'stdafx.h':No such file or directory".

Now I'm looking for a solution to this problem. Do you know how to solve it?

Best Regards,

The Zip attached below has the project folder, open the .vcxproj project file and build. It was created in VS 2013 so your newer version will want to upgrade it.

Hello John,

Thank you for your help.

I tried your zip file and  I could build it in VS2022. But, the size of exe file bult was 0 byte. I don't know the reason why.

So,I copied the files "stdafx.h", "targetver.h" and "stdafx.cpp" to my VS2022 project folder , then I could build it sucessfully.

When it starts running, it outputs error message "Count must be integer multiple of packet size for Continuous mode.".

So, I push Enter key, it outputs text "146". Next, I push Enter key again, it outputs the message "Completed...press any key to exit".

When it runs, I applied a voltage of about 4V DC only to CH0.

How can I avoid this error?

Try changing #define PACKET 31 to #define PACKET 64.

Thanks
