Timer based PWM output for MAX326XXFTHR platforms

Dependents:   MAX32620FTHR_PwmBlinky

Fork of MAX326XXFTHR_PwmOut by Jesse Marroquin

This library provides PWM output using the MAX32620/MAX32630 32-bit timers.

The mbed PwmOut API implementation uses Pulse Train peripherals.

The tables below contain the available GPIO pins that can be connected to the six 32-bit timers (TMR0-5). Timer 0 is used for the microsecond ticker API and is not available for PWM output. On the MAX32630FTHR platform, timer 5 is used by the BLE API and will not be available for PWM output if the BLE API is used.
