Abstract
In some examples, this disclosure describes a light-emitting diode (LED) driver circuit comprising a set of LED drivers, wherein each LED driver of the set of LED drivers is configured to control one or more LEDs of a set of LEDs. Additionally, the LED driver circuit comprises a core computing device configured to receive LED control information, compare primary path LED driver control output data with secondary path LED driver control output data to detect whether one or more error conditions are present in the core computing device, receive channel status feedback information, compare the secondary path LED driver control output data with the channel status feedback information to detect whether one or more error conditions are present in the set of LED drivers or in the set of LEDs, and trigger, based on determining that one or more error conditions are present, one or more remedial actions.
