mfiore 0:2c71706c23d3 2 *
mfiore 0:2c71706c23d3 3 * This program demonstrates how to write digital outputs using the
mfiore 0:2c71706c23d3 4 * MultiTech Dragonfly and MultiTech UDK2 hardware. The only
mfiore 0:2c71706c23d3 5 * additional hardware required is LEDs. Connect the LEDs between the
mfiore 0:2c71706c23d3 6 * bus pins and ground.
mfiore 0:2c71706c23d3 7 *
mfiore 0:2c71706c23d3 8 * Pins are active low, so 0V = 0 and 5V/3.3V = 1.
mfiore 0:2c71706c23d3 9 *
mfiore 0:2c71706c23d3 10 * This program blinks the D3 LED using a DigitalOut pin and writes
mfiore 0:2c71706c23d3 11 * to pins D9, D10, and D12 as a 3 pin bus.
