The problem with ESP 32 flashed micropython.

[Darklorian]

Greetings to all. Today I tried to work with ESP 32 for the first time by connecting PWM sg-90 to it, and I ran into the problem that the signal to the servo simply does not come out. I tried to re-connect pins and change pins in the code itself, but literally nothing helps. I tested this servo in parallel on an arduino uno, and it works. Perhaps I do not know any subtleties, or is it still a defective part?

My code:

Code: [Select all] [Expand/Collapse]

1. >>> from machine import Pin, PWM
2. >>> pwm = PWM(Pin(15))
3. >>> pwm.duty(15)
4. >>> pwm.freq(50)
5. # ignores my actions

At the same time, the same pin on IN works
