SysFS
The SysFS driver is still under development. Please report any issues or feature requests.
SysFS driver included in the kernel module provides easy file-based access to all IOs. 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 in a similar way.
