There is. According to to the trm , the timer prescaler is 16 bit and it normally gets fed from the 80MHz APB clock. That means that the minimum resolution is (80MHz/65535=)1221Hz. On the other side of the coin, the timer itself is 64 bit (56 bit on later ESP32-Cx/ESP32-Sx) which gives you 7 thousa...

Hello, I'm trying to port some code form v4.4.2 to v5.5.1, in this case about using the new GPTimer (Timer Group Before).
