ImHoTePHuN 0 Posted April 11, 2022 Dear all, I'm using "System.Device.Gpio" 2.1.0 library in VS in C# to control the GPIO-s of the TinkerBoard 2S. When I try to open the pin I get the following error : "Pin 18 does not support mode InputPullDown". I have encountered this problem before on Rpi4, but when I updated the nuget package, the problem went away. Can this package be used with the TinkerBoard 2S ? ( If not, could anyone suggest a working package ? ) Any help would be appreciated. Thanks in advance Share this post Link to post Share on other sites
yi-hsin_hung 3 Posted May 17, 2022 Hi @ImHoTePHuN: Could you use the wiringPi C library for TinkerBoard 2S because TinkerBoard 2S didn't support "System.Device.Gpio" 2.1.0 library in VS in C# now. Please reference the following information: - Tinker Board 2S wiki https://github.com/TinkerBoard/TinkerBoard/wiki/User-Guide#gpio-config-table-for-tinker-board-2s - WiringPi library API and functions: http://wiringpi.com/ Thank a lot!
