Function Documentation

Led_get()

bool Led_get

(

uint8_t

led_id

)

Get the given LED current state.

Parameters

led_id

Id of the led

Returns

True if ON , false if OFF

Led_getNumber()

uint8_t Led_getNumber

(

void

)

Get number of leds available.

Returns

The number of leds available

Examples

blink/app.c.

Led_init()

void Led_init

(

void

)

Initialize Led module.

Example on use:

void App_init(const app_global_functions_t * functions)
{
    ...
    // Set up LED GPIO
    Led_init();
    ...
}

Led_set()

led_res_e Led_set	(	uint8_t	led_id,
		bool	state
	)

Turn the given LED on or off.

Example on use:

#define LED_NUMBER          0
 
void App_init(const app_global_functions_t * functions)
{
    ...
    // Set up LED GPIO
    Led_init();
    Led_set(LED_NUMBER, true);
    ...
}

Parameters

led_id	Id of the led
state	True to switch ON, False to switch OFF

Returns

True if successful, false otherwise

Examples

blink/app.c, and positioning_app/app.c.

Led_toggle()

led_res_e Led_toggle

(

uint8_t

led_id

)

Toggle the given LED.

Parameters

led_id

Id of the led

Returns

True if successful, false otherwise

Examples

ble_scanner/app.c, and scheduler/app.c.
