INTERFACES AND TECHNIQUES FOR COST EFFECTIVE CONTROL OF LIGHT EMITTING DIODES IN A VEHICLE

A control circuit may be configured to control light emitting diode (LED) driver circuits. The control circuit may be configured to generate a multicast of pixel intensity values based on data in memory or data received from a data source, and output the multicast on an interface, which may comprise a one-wire uni-directional interface. In some examples, a plurality of drivers may receive the multicast, and each of the plurality of drivers may drive different sets of LEDs based on the multicast.
