TC08OpenUnit()
Hello,
I have just tried to write a basic program to interface to the USB TC08 data logger in a C# .Net WinForms application (64 bit, Visual Studio 2022 on Windows 10). I have installed the latest 64 bit SDK and also the Pico Logger (downloaded yesterday from the site). The Pico logger software works fine. I have downloaded the USBTC08Imports.cs file from the Github repository linked to on the Pico website and also checked the example code available there too.
When I call TC08OpenUnit() with the logger attached as the first interaction, the program hangs for a second and then crashes out. Event in Debugger mode, the program crashes out completely and the debugger cannot catch any error.
If I make the same call with the Pico logger software running, then the code works correctly (and I get a handle of 0 as the logger is already in use). If I make the call without the logger physically connected (and no Pico logger software running), the the code completes successfully indicating no unit found as you would expect. But if I connect the logger and then make the same call, the program crashes without returning from the TC08OpenUnit() routine
The USBTC08Imports.cs file does not include a call to TC08OpenUnitAsync() in it's definitions, but I have added the appropriate definition and link to the DLL file to try and I get the same result. If the logger is not connected, then calling the TC08OpenUnitAsync() routine also crashes the program after a second with no indication of error or with teh debufgger able to capture anything.
I have made the call to TC08OpenUnit() get called when a button is clicked so I can establish that the program is fully stable and nothing else is running. I also see the green LED on the logger come on.
Has anyone else used the unit with an app in C# successfully?
Thanks
Kevin Corcoran
