Use theLEDC, or the MCPWM, or maybe even the RMT peripheral if you have to, but please, for everything that's holy to you, don't try to create that PWM signal in software on an ESP32. There are too many things (interrupts, multi-tasking,...) going on in the background for you...
Breaks the ethernet. So this is not firmware or software stuff. I just configure the GPIO matrix registers. Configuring these bits the MCPWM signal appears at the output however the ethernet is broken (as it is in my example). The values of these bits: ...
It also supports motor control features through internal registers of the ESP32 chip. ESP32 supports two MCPWM units. These MCPWM units can be used to control motors directly. Each MCPWM has three pairs of outputs mentioned below. you just need to configure these registers with any GPIO pins....

I'm planing to make 3-phase variable frequency drive with esp32. I would like to generate 3 high-side hardware PWM and inverted 3 low-side hardware PWM with inserted dead time to charge bootstrap capacitor. I've been playing with MCPWM library on arduino IDE. My questions are: 1. How...

Currently my ESP32 boards on my library installed is Arduino ESP32 Boards 2.0.18 and ESP32 by Expressif Systems is version 3.07 both installed. Where do I get the version 3 of ESP32 boards you’re suggesting. Sorry I’m just new to this libraries. I got this information from my ...
