/*
 * Title: WritePwmOutput
 *
 * Objective:
 *    This example demonstrates how to write a digital PWM signal to a ClearCore
 *    digital output.
 *
 * Description:
 *    This example sets the defined pin as an output then writes a series of
 *    PWM signals with varying duty cycles to the output.
 *
 * Requirements:
 * ** Connect a device that takes in a PWM signal to IO-1.
