JOYState_TypeDef BSP_JOY_GetState ( void )

Returns the Joystick key pressed.

Note:

To know which Joystick key is pressed we need to detect the voltage level on each key output

None : 3.3 V / 4095
SEL : 1.055 V / 1308
DOWN : 0.71 V / 88
LEFT : 3.0 V / 3720
RIGHT : 0.595 V / 737
UP : 1.65 V / 2046

Return values:

JOYState_TypeDef,: Code of the Joystick key pressed.
