I wondering how I can find the correct pin input/output on linux?
I want to connect a dht22 sensor to STM32MP157C through a gpio but I can’t figure out how to find correct pin in linux…
I don’t have any directory called GPIO in /sys/class and when I’m looking at gpiochip,I’m just confused.
I’m programming in C, if there a library for gpio, I’m happy to know.
thanks in advance.
