Interface and technique for economical and efficient control of light emitting diodes in vehicles

Embodiments of the present disclosure generally relate to interfaces and techniques for economical and efficient control of light emitting diodes in vehicles. A control circuit may be configured to control a light emitting diode (LED) driver circuit. The control circuitry may be configured to generate a multicast of pixel intensity values based on data in the memory or data received from a data source, and output the multicast on an interface, which may include a single wire unidirectional interface. In some examples, a plurality of drivers may receive a multicast, and each of the plurality of drivers may drive a different group of LEDs based on the multicast. 本公开的各实施例总体上涉及用于车辆中的发光二极管的经济高效控制的接口和技术。一种控制电路可以被配置为控制发光二极管(LED)驱动器电路。该控制电路可以被配置为基于存储器中的数据或从数据源接收的数据生成像素强度值的多播，并且在接口上输出多播，该接口可以包括单线单向接口。在一些示例中，多个驱动器可以接收多播，并且多个驱动器中的每个驱动器可以基于多播来驱动不同组LED。
