ESP32 S3 WROOM + WiFi Power usage

I have two nearly identical boards, one with ESP32-S3-WROOM-1-N8R8 and the other ESP32-S3-WROOM-1-N8R2 and I'm using Nordic Power Profiler Kit II to observe power consumption. In both cases, WiFi is enabled but no active data transfer is occurring, and I'm just looping and sleeping. What I see is wi...

ESP32-S3 doesn't boot after long disconnection from power

Re: ESP32 S3 LEDC and PWM dithering

Really, nobody else knows about this? I'm referring to this section in the manual: However, when B is nonzero, LEDC_CLK_DIV becomes a non-integer divisor. The clock divider implements non-integer frequency division by alternating between A and (A+1) LEDC_CLKx clock pulses per ref_pulsex clock pulse....

ESP32 S3 LEDC and PWM dithering

It looks from the manual that the chip supports dithering using the lower 4 bits of the duty cycle, but I don’t seem to see support in the API for this. Am I missing it?
