The development software with USB-201

[Roger Lo]

Dear all,

There's a customer who has a development issue on USB-201.

The user cannot read any data from their owned developed application. 

 

The output voltage is 0V.

 

The program cannot be executed with Visual Studio 2017.

HOWEVER, it works OK with Visual Studio 2019.

But the user only purchases 2019 version.

 

I'm wondering if there is any way or patch for 2017 that can make the program execute successfully in Visual Studio 2017.

Thank you

We are aware of no reported problems regarding Visual Studio 2017. There's likely a programming mistake; for example, there is no test to determine if TestBoard is valid, and the error status needs to be checked when executing the AIn function call. I am attaching a USB-201 test program that returns data from the first four channels for display.
