Hello, I need a rock-solid (hardware PWM) for precise motion control, at only 1800-1980 Hz at the pin. Really it only needs to be 50% at all times.
My understanding is just using some random I/O pin for PWM may give a lot of jumping (I have seen it myself) due to creating it in software, rather than a timer register. It appears I/O 12 is good for hardware/solid pwm, but what library will drive it as a hardware wave (rather than software)? Which packages are software only? I haven't seen it stated one way or the other.
Also I have another PWM device on GPIO22...what is the best I can do there? need about 1500Hz, 50%
