Abstract
A method for driving a set of light emitting diodes (LEDs) may include receiving a write access frame by a driver via a bus configured for connection with a controller and the driver. The write access frame includes brightness information. The method may further include controlling, by the driver, the set of LEDs based on the brightness information and determining, by the driver, safety information while controlling the set of LEDs based on the brightness information. The method may further include outputting, by the driver and at the bus, the safety information to acknowledge receipt of the write access frame.
