Macros
#define	OUT_ON   GPIO_PIN_RESET
	Pin level that turns an output ON. LEDs are wired 5V -> resistor -> LED -> GPIO, so low = lit; the buzzer module sounds when its signal pin is low.
#define	OUT_OFF   GPIO_PIN_SET
	Pin level that turns an output OFF (LED dark, buzzer silent).

Functions
static void	outputsAllOff (void)
	Drives all three LEDs and the buzzer to their OFF level (LEDs dark, buzzer silent).
static void	applyZoneAction (touchZone_t zone)
	Applies the action for a settled touch zone. LEDs latch: an ON zone turns that LED on and an OFF zone turns it off. The buzzer sounds only while the BEEP zone is held, so any non-BEEP zone silences it.
int	main (void)
	The application entry point.

Function Documentation

applyZoneAction()

static void applyZoneAction ( touchZone_t zone )

static

Applies the action for a settled touch zone. LEDs latch: an ON zone turns that LED on and an OFF zone turns it off. The buzzer sounds only while the BEEP zone is held, so any non-BEEP zone silences it.

Parameters

zone	The zone that just settled (see touchZoneFromPoint()).
