Birectional GPIO setting

Embedded Linux Discussions

Hi Robert,

The /sys/class/gpio/gpioNNN can take in or out parameters for direction to setup as input or output. Is there a way to setup a GPIO pin as bidirectional ? (through port register?)

Best Regards,
David

Hi @dzhou the old /sys/class/gpio interface only supports in or out options.
