/*
 * Portenta Machine Control - Thermocouples Temperature Reading Example
 *
 * This example reads the temperatures measured by the thermocouples
 * connected to the temp probe inputs on the Portenta Machine Control Carrier.
 * It prints the temperature values to the Serial Monitor every second.
 *
 * Circuit:
 *  - Portenta H7
 *  - Portenta Machine Control
 *  - Two K Type thermocouple temperature sensors connected to TEMP PROBES CH0 and CH1
 *  - A J Type thermocouple temperature sensor connected to TEMP PROBES CH3
 *
 * This example code is in the public domain.
