douglasc 0:286a51986128 2 * Interactive Device Design, Fall 2014
douglasc 0:286a51986128 3 * Homework 2 - Text Entry Device
douglasc 0:286a51986128 4 * Doug Cook
douglasc 0:286a51986128 5 *
douglasc 0:286a51986128 6 * This program will setup a 7-button text-entry device
douglasc 0:286a51986128 7 * with 5 keys corresponding to the binary numbers 1 - 32
douglasc 0:286a51986128 8 * which then map to the alphabet, starting at 1. The
douglasc 0:286a51986128 9 * remaining two keys act as space and shift keys. Extra
douglasc 0:286a51986128 10 * numbers beyond the 26 alpha character map to the
douglasc 0:286a51986128 11 * question mark. This program allows the Freedom KL25Z
douglasc 0:286a51986128 12 * act as a USB Keyboard (using the non-debug USB port).
