  Machine Control - IOExpander Read And Write Example

  This sketch shows how to use the GPIO Expanders on the Machine Control,
  how to periodically send a value on the PROGRAMMABLE DIGITAL I/O
  output channels and how to periodically read from the PROGRAMMABLE
  DIGITAL I/O input channels.

  The circuit:
   - Portenta H7
   - Machine Control

  This example code is in the public domain.
