- Fri Jul 10, 2015 3:08 pm #22944 No no no I did'nt write a library for PWM. It's in the SDK. Have a look at the include file pwm.h, it's all there.

- Fri Jul 10, 2015 3:13 pm #22945 Honestly, I do not know if the PWM is hardware or not. I used the PWM through the Arduino SDK with analogWrite. On the oscilloscope it looks like any regular PWM to me. I do not know what the resolution is. I did not try to measure it. You could probably filter the hell out of it with capacitors and then measure the voltage with a good DMM every step to see if it changes at 8 bit, 10 bit or greater.

Just been looking for that . Can u tell me where it lives?
I searched and got the Arduino site and looks like I've got some heavy reading to do
