Michael Hennessy
A skydiving game created using an mbed. This code used threads and mutexes to create a skydiving simulation on an uLCD. The sounds being played are read off of a microSD card and played through the speakers. The user controls the skydiver's movements with a navigation switch.
Dependencies: 4DGL-uLCD-SE SDFileSystem mbed-rtos mbed wave_player
