Hello,
I can use a pin as an output gpio with a led driver, but I want to use it with libgpiod commands. For example I want to set the pin status to 1 and 0 with “gpioset”. How can I do that? How should the device tree definition be? Can you share an example? Thanks

Hello @eepvs ,
You can have a look at our documentation articles:

Are you using TorizonOS or one of our reference images?

Best regards,
Josep
