  Machine Control - Analog out Example

  This example shows how to use the Analog out channels on
  the Machine Control.
  The example sets the channels PWM period in the setup,
  then loops the channels voltage output value from 0V to 10.4V.

  The circuit:
   - Portenta H7
   - Machine Control

  This example code is in the public domain.
