/*
 * Portenta Machine Control - Digital Output Example
 *
 * This sketch shows how to send values on the DIGITAL OUT channels on the Machine Control.
 * The DIGITAL OUT channels are high-side switches capable of handling up to 0.5A.
 * There is an overcurrent protection that opens the channel when the current exceeds 0.7A with a +-20% tolerance.
 * The overcurrent protection can be set to operate in two different modes for all channels:
 *   1) Latch mode: When overcurrent is detected, the channel remains open until toggled via software.
 *   2) Auto retry: When overcurrent is detected, the channel opens, but after several tens of milliseconds,
 *      it attempts to close itself automatically. If overcurrent persists, the channel will continuously toggle.
 *
 * Circuit:
 *  - Portenta H7
 *  - Portenta Machine Control
 * 
 * NOTE: connect pin "24V IN" of the DIGITAL_OUTPUTS connector to 24V
 *
 * This example code is in the public domain.
