Function Documentation

is31fl3733_blank()

int is31fl3733_blank	(	const struct device *	dev,
		bool	blank_en
	)

Blanks IS31FL3733 LED display.

When blank_en is set, the LED display will be disabled. This can be used for flicker-free display updates, or power saving.

Parameters

dev	LED device structure
blank_en	should blanking be enabled

Returns

0 on success, or negative value on error.

is31fl3733_current_limit()

int is31fl3733_current_limit	(	const struct device *	dev,
		uint8_t	limit
	)

Sets led current limit.

Sets the current limit for the LED driver. This is a separate value from per-led brightness, and applies to all LEDs. This value sets the output current limit according to the following formula: (840/R_ISET) * (limit/256) See table 14 of the datasheet for additional details.

Parameters

dev	LED device structure
limit	current limit to apply

Returns

0 on success, or negative value on error.
