ESP32 PWM frequency bug

Post by eragon24ß4 » Thu Jul 07, 2022 3:02 pm

Hi!
I need a PWM frequency of 400 on my ESP32 but it wont go lower then 611Hz.
I found this post https://github.com/micropython/micropython/pull/8200 discussing a solution.
Problem is: i also need ESPNow. Is there any build with ESPNow AND the frequency fix?

Please update the firmware. This bug has been fixed a while ago.

Afaik the normal versions of mycropython still dont support ESPNow.
Luckily glenn posted ESPNow versions of micropython 1.19 just two days ago!
