mfiore 0:4a3a5f1bdca6 3 * This program demonstrates how to do pulse width modulation on
mfiore 0:4a3a5f1bdca6 4 * and output pin using the MultiTech Dragonfly and MultiTech UDK2
mfiore 0:4a3a5f1bdca6 5 * hardware. The only additional hardware required is a LED.
mfiore 0:4a3a5f1bdca6 6 *
mfiore 0:4a3a5f1bdca6 7 * This program PWMs the D12 pin. It should go from 0% to 100% duty
mfiore 0:4a3a5f1bdca6 8 * cycle in 5% increments and then from 100% to 0% in 5% increments.
