Function Documentation

void LED_Display

(

uint32_t

leds

)

Sets the state of all LEDs.

Parameters:

void LED_Display_Field	(	uint32_t	field,
		uint32_t	leds
	)

Sets as a bit-field the state of the specified LEDs.

Parameters:

field	LEDs of which to set the state (1 bit per LED).
leds	New state of the specified LEDs (1 bit per LED, beginning with the first specified LED).

Note:

The pins of the specified LEDs are set to GPIO output mode.

Here is the call graph for this function:

void LED_Display_Mask	(	uint32_t	mask,
		uint32_t	leds
	)
