ESP32-S2 High Frequency PWM Issues

Postby mrea303 » Wed Oct 19, 2022 6:09 am

I'm having issues getting PWM above 30khz, I'm using the Arduino Framework and using the LEDC functions. Resolution is 10bit and should be able to get 78khz. If I run the same code on standard ESP32 I can get the 78khz. So it seems to be an issue with the S2 version. From digging through docs I see something about low speed, but it can still use the 80mhz timer. Is there any additional parameters I need to set? Thanks
