/*
 * Title: WriteCCIODigitalOutput
 *
 * Objective:
 *    This example demonstrates how to initialize a CCIO-8 Expansion Board and
 *    write to its outputs.
 *
 * Description:
 *    This example sets up COM-0 to control a CCIO-8 Expansion Board then
 *    toggles the state of all of the CCIO-8's outputs from true to false.
 *
 * Requirements:
 * ** A CCIO-8 Expansion Board powered and connected to COM-0.
 * ** An output such as an LED connected to one or more of the CCIO-8's
 *    connectors.
 *      Note: You can leave the I/O points disconnected and still see the
 *      built-in I/O LEDs toggle with the connector state.
 *
 * Links:
 * ** ClearCore Documentation: https://teknic-inc.github.io/ClearCore-library/
 * ** ClearCore Manual: https://www.teknic.com/files/downloads/clearcore_user_manual.pdf
