"NettetThe LEDC output component exposes a LEDC PWM channel of the ESP32 as an output component. The frequency range of LEDC is from 10Hz to 40MHz - however, higher frequencies require a smaller bit depth which means the output is not that accurate for frequencies above ~300kHz.

NettetTake 1hz (1000000 microseconds) divide by 375 microsecond period per pulse, and that should give us our frequency for the LEDC module which is approximately 2666hz in this example. If I test this 1/8th microstepping at 2666hz on the LEDC, then everything works great! If I switch the mode to 1/64 micro stepping, then the motor goes 1/4 of the speed.
