- pwm-write pin valueprocedure
Writes the value to the PWM register for the given pin. The Raspberry Pi has one on-board PWM pin, pin 1 (BMC\_GPIO 18, Phys 12) and the range is 0-1024. Other PWM devices may have other PWM ranges.
This function is not able to control the Pi’s on-board PWM when in Sys mode.
