 * File:     generator.c      
 * Author:   Charles Gruenwald III - [e-mail]
 * Date:     12-14-2003
 *
 * Description: generator will repeatedly send the numbers 1,2,3...255 
 * over the radio and display the last 3 bits in binary on the LEDs. it 
 * is to be used with receiver.c to test the radios on compatable 
 * hardware (nymph/mica2).
