udev for i2c and gpio

Recommended Posts

If anyone is looking at fixing the access for gpio and i2c - I found you can fix it with the following udev rules

addgroup --system i2c
addgroup --system gpio

 

create in /etc/udev/rules.d/60-i2c-tools.rules

SUBSYSTEM=="i2c-dev",KERNEL=="i2c*", GROUP="i2c", MODE="0660"

 

create in /etc/udev/rules.d/61-gpio-tools.rules

SUBSYSTEM=="gpio",KERNEL=="gpiochip*", GROUP="gpio", MODE="0660"
