Requires python3, python-uinput and RPi.GPIO
|
||||
|
||||
Make sure that user pi can open the uinput device.
|
||||
|
||||
Enable access to it:
|
||||
sudo groupadd -f uinput
|
||||
sudo gpasswd -a pi uinput
|
||||
Open /etc/udev/rules.d/99-input.rules and add:
|
||||
SUBSYSTEM=="input", GROUP="input", MODE="0660"
|
||||
KERNEL=="uinput", GROUP="uinput", MODE="0660"
