How to use

make
sudo make install

This will create a systemd service, and this service will automatically start on boot. By default, it will listen for pwm command sent to pin 13 and 18, and set the mode of these pins to PWM_OUTPUT. To change the this, modify pwmWriter.service, then run sudo make reload-service.

To send pwm command to the specific pin, write an integer to /dev/gpiopwm/x.

echo 512 > /dev/pwmgpio/13 # This will invoke pwmWrite(13, 512) in wiringPi.
