Web25 jan. 2024 · Hi guys, I'm running Mega with Marlin firmware (as my 3d printer controller) which to my understanding has its PWM set to 1 kHz. I want to control a 4-wire fan with PWM from 30% to 100% and to reduce noise I've decided to use the manufacturer's recommended 25 kHz (I won't need to read the tacho).I think I won't need to worry about … Web25 okt. 2024 · It's a PWM, so the number of distinct values each PWM sample can have is equal to the clock frequency used by the timer divided by the PWM period. If we have 16MHz clock and a period of 16 cycles, we can have Fs=2 MHz, but we have only 16 output levels, ie a 4-bit DAC. So the sine will look jaggy unless dithering is applied.
