Page 5: Pulse Width Modulated Dc Motor Driver Outputs
The Raspberry Pi microcomputer supports two hardware PWM outputs: PWM0 and PWM1, each of which can be mapped to several GPIO pins. The following device tree overlay command must be appended to /boot/config.txt to configure the Raspberry Pi PWM subsystem for the MUNTS-0018 Tutorial I/O Board: dtoverlay=pwm-2chan,pin=12,func=4,pin2=19,func2=2 Pin Mapping... -
