Thanks, 1907Hz seems to be the default setting from Pico poweron then.
I would expect there is an explanation for this frequency when looking up RP2040 datasheet.
It is same 1907Hz PWM frequency and duty 0 for all pins:
Code: Select all
>>>
MPY: soft reboot
MicroPython v1.17 on 2021-09-02; Raspberry Pi Pico with RP2040
Type "help()" for more information.
>>> from machine import PWM,Pin
>>> for i in range(2, 22+1):
... p=PWM(Pin(i))
... print(p.freq(), p.duty_u16())
...
...
...
