I dont know if it matters, but this is the C3 variant I am using

And I have installed the dev branch which fixed previous C3 bugs

Hi, quick PR here. This was the only way I was able to make this board work …-> https://www.espboards.dev/esp32/esp32-c3-super-mini-plus/ No matter which pins I used, I was intermittently 3 out of 5 boots getting the following error: ``` EP32-DRV: Configuring 3PWM EP32-DRV: 3PWM setup in group: 0 E (290) ledc: ledc_channel_config(847): sleep_mode argument is invalid EP32-DRV: ERROR - Failed to attach channel:0 EP32-DRV: ERROR - Failed to configure pin:1 ``` This PR fixes it. I don't know if this is a good solution, but works bulletproof for the C3 board in quesiton. Open to discuss. Thanks.
