MCPWM servo motor control Example

This example will show you how to use MCPWM module to control servo motor

Assign pulse width range and the maximum degree, accordingly the servo will move from 0 to maximum degree continuously

Step 1: Pin assignment

  • GPIO15 is assigned as the MCPWM signal for servo motor

Step 2: Connection

  • connect GPIO15 with servo pwm signal
  • other two wires of servo motor are VCC and GND

Step 3: Initialize MCPWM

  • You need to set the frequency(generally 50 Hz) and duty cycle of MCPWM timer
  • You need to set the MCPWM channel you want to use, and bind the channel with one of the timers
