Thanks... But that is not an option, due to the "aesthetics" of the movement. I want seamless analog like movement. But your suggestions is a way, for sure. Thanks!

Fair enough, in which case I'd go for stepper motors.

You can also setup the PWM yourself.

For example, this code:

Code: Select all

servo_pin = pyb.Pin.board.X1
t5 = pyb.Timer(5, prescaler=83, period=19999);
servo = t5.channel(1, pyb.Timer.PWM, pin=servo_pin)
servo.pulse_width(1000)
allows 1 usec resolution on the pulse width. The regular servo library only allows 10 usec resolution.

Hello, has anyone tested the library on ESP32 ?

I have some trouble to make it work.
Thanks
