This is a simple python script that maps the GPIO pins of a Raspberry Pi to keyboard keys for use with the Dirtywave m8 headless tracker on a Raspberry Pi 4.
See https://github.com/RowdyVoyeur/m8c-rpi4 for details on that project.
gpio-hw-keyboard.py maps the GPIO pins to keyboard keys to control the m8c.
26: "up",
19: "right",
13: "down",
6: "left",
21: "a", #option
20: "s", #edit
16: "z", #shift
12: "x", #play
gpio-volume-control.py maps the GPIO pins to volume control buttons.
23: Volume Up
24: Volume Down
listen-for-shutdown.py and listen-for-shutdown.sh are used to listen for a button press to shut down the rPi. This is intended to be used with a momentary switch connected to GPIO pin 3 and ground.
Install with:
./m8c-rpi-gpio/script/install
Install required packages at root
sudo pip3 install keyboard pyalsaaudio
Copy the service file to systemd
sudo cp ~/m8c-rpi-gpio/m8c-rpi-gpio.service /etc/systemd/system/m8c-rpi-gpio.service
Enable and start the service
sudo systemctl daemon-reload
sudo systemctl enable m8c-rpi-gpio.service
sudo systemctl start m8c-rpi-gpio.service
sudo python3 main.py
