Servo library

[mflmartin]

An easy way might be to use a standard 180 degree servo and gear it up 2:1. The only snag is that at (say) 11.59 the clock's hand would sweep through 354 degrees backwards to get to 12.00.

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
