GpioTestTool
-
I am trying to access the GPIO of an embedded computer. The device was installed with Windows 10 Pro 20H2 x64 (not my decision). I installed the vendor specific drivers, and the GPIO device is shown with "Intel(R) Serial IO GPIO Host Controller - INT34BB" in the device manager. I searched the internet and could find a “GpioTestTool” (https://github.com/ms-iot/samples/tree/develop/GpioTestTool) which I could compile on my development machine. After installing “Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019” (“VC_redist.x64.exe”) on the embedded machine, I could start the program. It shows following error message: “Error: GPIO is not available on this system” This error message is also shown when I start the program as an administrator. That is, the program fails to detect the GPIO. Can you suggest any tools for trouble shooting?
Oh sanctissimi Wilhelmus, Theodorus, et Fredericus!
