ESP32 PWM

[Alan_37]

Hi, I am trying to enable a simple PWM channel on esp 32 but it's not working
and I get the following message from the serial output.



.[0;31mE (13798) MCPWM: C:/esp-idf/components/driver/mcpwm.c:202 (mcpwm_set_duty):MCPWM DRIVER NOT INITIALIZED.[0m
.[0;31mE (13898) MCPWM: C:/esp-idf/components/driver/mcpwm.c:202 (mcpwm_set_duty):MCPWM DRIVER NOT INITIALIZED.[0m

Hello,

Pins B2 to B7 are all input only on the ESP32 devices.

Please can you try a different pin to see if that solves the problem for you.

Thanks for your help.
