int | is31fl3733_blank (const struct device *dev, bool blank_en) |
Blanks IS31FL3733 LED display. | |
int | is31fl3733_current_limit (const struct device *dev, uint8_t limit) |
Sets led current limit. | |
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.

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.
