What is this for a LPC 1768? My board is running at 100mhz vs the 16mhz of the AVR boards but I am unsure if the scale/frequency has changed in Marlin 2.0 for this controller.

Is the ~7hz we get on the avr boards the same as we get on the 100+ mhz ARM boards?

The heaters use the same ~7Hz. The other PWM pins (servos, RGB and fans) default to 50Hz on LPC1768 boards.

Good to know. Seems my external mosfet doesn't like PID control at 7hz.
