Hello,

does anyone have experience with generating a sine wave using pwm (on ESP32 or 8622), need to drive MOSFETs for a single phase inverter like:

Dear,

the problem was in the Chinese servo motor that was not working properly,
by replacing the motor, everything works!

Thank you very much for the answers and time!

OK! Thanks a lot!
I'll have to try another servo!

Forth and back in small steps!
freq = 50
duty = (95-130) # from 95 to 130

In case I don't use deinit (), it's as if there is some interference (signal) that moves the servo in small movements! I am not an expert in the field of microcontrollers ... My field of expertise is acoustics and audio signal processing ... Is there an error in the code given in the previous post?

I just tried this code on the MicroPython v1.16 on 2021-06-23; ESP32 module with ESP32, and everithing work!

That it is not a mistake in the version v1.17...?

Sorry, it doesn't seem to be a mistake in the firmware and timing! Is pwm.deinit () automatically sent commands to return the servo to the starting position and is it possible to change it? This is my code for servo motor control: '''klapna''' class klapna: def __init__(self, pozicija): self.pozicij...

Thanks a lot!

I'll try and report my impressions!

I have esp32, what is solution?

I have esp32-20210902-v1.17.bin.
