According to https://store.arduino.cc/usa/arduino-mkrzero there are 12 PWM-capable pins, specifically:
PWM Pins: 12 (0, 1, 2, 3, 4, 5, 6, 7, 8, 10, A3 - or 18 -, A4 -or 19)
I'd like to use 10 of those pins to dim 10 LED driver circuits. Before I buy anything I just had a few questions that I think somebody might know the answers to:
- Is it possible to actually use all of those PWM pins simultaneously, and be able to independently set their duty-cycle values (via analogWrite())? I don't need different PWM frequencies.
- Also, I'm slightly confused where the pin numbers "18" and "19" are coming from---there are no references to a pin 18/19 in the MKR ZERO schematic. Is that just a copypasta from the tech specs of a different MKR series Arduino?
My backup plan is to use a separate I2C-controlled DAC with multiple outputs to feed each of the LED driver circuits, but I would like to forgo that extra complexity if I can simply call analogWrite() on those PWM pins.
Thanks!
