BUTTONS: One single button

The following code shows how to sample the buttons main functions using a period of tie of 10ms, the with another one we can poll when the button reports an event every 50ms, because we need 5 samples to determine if the button was pressed or released

#include "bsp.h"
#include "buttons.h"
