/*
 * Title: WriteDigitalOutput
 *
 * Objective:
 *    This example demonstrates how to write the state of a ClearCore digital
 *    output.
 *
 * Description:
 *    This example repeatedly toggles the state of the ClearCore's six digital
 *    outputs, IO-0 through IO-5.
 *
 * Requirements:
 * ** A device that takes in a digital signal connected to any of the I/O's,
 *    IO-0 through IO-5.
 *      Note: You can leave the I/O points disconnected and still see the
 *      built-in I/O LEDs toggle with the connector state.
