Title
Remote Counting of Serially Connected Components Using a Controller
Abstract
A system that includes a plurality of serially connected light emitting diodes (LEDs), a latch circuit, and a controller including logic is disclosed. A first plurality of bits is transmitted from the controller to a first LED of the plurality of serially connected LEDs. The plurality of serially connected LEDs includes the first LED, coupled to the controller, and a last LED coupled to the latch circuit. The controller determines that the latch circuit is set. The latch circuit is set based on an output of the last LED after the transmitting the first plurality of bits. The number of active LEDs in the plurality of serially connected LEDs is identified, based on determining that the latch circuit is set.
