#define LEDS_NUM_TO_MASK | ( | l | ) | (1 << (l)) |
A LED logical representation.
pin corresponds to the GPIO pin a LED is driven by, using GPIO HAL pin representation.
port corresponds to the GPIO port that the pin is connected to. This only makes sense if GPIO_HAL_CONF_PORT_PIN_NUMBERING is non-zero.
negative_logic should be set to false if the LED is active low.
leds_mask_t leds_get | ( | void | ) |
void leds_init | ( | void | ) |
Initialise the LED HAL.
This function will set corresponding LED GPIO pins to output and will also set the initial state of all LEDs to off.

void leds_off | ( | leds_mask_t | leds | ) |
Turn off multiple LEDs.
leds | The leds to be turned off as an OR mask |
The led argument should be a bitwise mask of the LEDs to be changed. For example, to turn on LEDs 1 and 3, you should pass LED_NUM_TO_MASK(LED_L1) | LED_NUM_TO_MASK(LED_L3) = 1 | 4 = 5
This function will not change the state of other LEDs.
