SysFS driver included in the kernel module for all Unipi controllers, except UniPi 1.1 and UniPi 1.1 Lite, provides easy file-based access to all inputs and outputs of the controller. Check the following examples to get started:
Set state of DO to 1
echo 1 > /sys/devices/platform/unipi_plc/io_group1/do_1_01/do_value
Read the state of DI
cat /sys/devices/platform/unipi_plc/io_group1/di_1_01/di_value
All IOs can be accessed similarly.
