The Jetson AGX Orin carrier board includes a 40-pin (2 × 20, 2.54 mm pitch) expansion header.As shown in the following figure:
I want to use the two free GPIO pins in the Expansion Header. Connect these two GPIO pins to two key modules. Then write a C++program in Orin to read the status of two key modules (i.e. whether they are pressed). What should I do or do I have any reference materials?
Thank you for your reply
Hello,
There is an official NVidia Python support for GPIO control GitHub - NVIDIA/jetson-gpio: A Python library that enables the use of Jetson's GPIOs
But also there is a C++ library: GitHub - pjueon/JetsonGPIO: A C++ library that enables the use of Jetson's GPIOs the API is very similar to Python version/
Both packages includes examples that you can modify with your requirements.
Please notice that some of the GPIO will require to change the PINMUX configuration.
