Thanks for checking it out!

I'm actually dumb that (40M >> 8) / 300 is actually close to 500.
I was mistaking >> 8 as divide 8 instead of divide 2^8.

The code is working as expected. Sorry for the confusion

Hi!

I'm developing a custom PWM driver based on the GPTimer.

Chip: ESP32S3
Borad: Adafruit ESP32S3 QTPY no psram

I tested a version on Arduino esp32, and it works as expected:


// Set timer frequency to 1Mhz
pctrl_timer = timerBegin(timerfreq);
timerAttachInterrupt(pctrl_timer, &VEMA_PWM ...
