LIN RGB Ambient Lighting

LIN RGB lighting consists of a LIN Commander (previously known as the Master) and up to sixteen Responder Nodes (previously known as Slaves). In this example the responder nodes are for ambient lighting and use the IS32LT3183A LED driver. Each LIN responder is interconnected in a serial daisy chain fashion with LIN_OUT connected to the next LIN_IN. The Bus Shunt Method is used at power up for detecting the node position within the daisy chain with each node assigned a unique address. In this ambient lighting application, each responder node can be either ON or OFF, display a different color, and different brightness. The IS32LT3183A can also replay stored lighting profiles that suit individual tastes and preferences for a more pleasing driving mood. LIN LEDs can be used in conjunction with other sensors to enhance safety, for example, by flashing ambient lights when driving off lane.
