Help Need - PWM Servo Control with ESP32-S2

[BivvyCoder]

I'm doing some development with an ESP32-S2 dev board and have been asked to add a servo motor.
I've tried the mcpwm_servo_control example in the IDE but can't get it to compile, for instance I get an error

• MCPWM_TIMER_CLK_SRC_DEFAULT undeclared

The code has the motor control PWM library included

Code: Select all

#include "driver/mcpwm_prelude.h"

If I change the target to ESP32-C3 it compiles fine (and looking at the Readme file, the S2 is not listed as supported, so I guess I shouldn't be surprised.)

Two questions.

• Is it possible to implement a PWM servo control with the S2?(This page suggests that PWM is supported https://docs.espressif.com/projects/esp ... -1-v1.html)

• If it is, can anyone point me at an example that I can test and then use to develop my own application?

Many thanks

You may be able to use the LEDC peripheral instead.

That's great - thanks
Managed to use LEDC to create the required PWM signals
