Filename: light_switch.c
Description: This application function either as a light or a
switch toggling the ligh. The role of the
application is chosen in the menu with the joystick at initialisation.
Push S1 to enter the menu. Choose either switch or
light and confirm choice with S1.
Joystick Up: Sends data from switch to light
