Abstract: An apparatus is provided that includes a controlled voltage source and processing circuitry. The controlled voltage source connects to one or more light-emitting diode (LED) leads of a light-emitting diode (LED) controller that is in communication with a host. The processing circuitry selects a particular one of a plurality of predetermined voltages based on upstream information to be communicated to the host. The processing circuitry causes the controlled voltage source to impose the particular one of the plurality of predetermined voltages on the one or more LED leads, and thereby communicate the upstream information to the host via the LED controller.

Abstract: An apparatus is provided that includes one or more leads and processing circuitry. The one or more leads are to connect the apparatus to one or more light-emitting diode (LED) leads of an LED controller. The processing circuitry is to receive a pulse-width modulation (PWM) signal from the LED controller. The processing circuitry decodes the PWM signal to recover downstream information from the PWM signal, and performs an operation based on the downstream information.
