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.

Abstract: In some examples, this disclosure describes a light-emitting diode (LED) driver circuit configured to: control a set of LED channels; receive, from each LED channel of the set of LED channels, channel status information that indicates whether the respective LED channel is activated or deactivated; and determine, based on the channel status information corresponding to each LED channel of the set of LED channels, a channel status of the respective LED channel. Additionally, the LED driver circuit is configured to output, to a master computing device, the channel status corresponding to each LED channel of the set of LED channels; and output, to the master computing device, channel mapping information, wherein the master computing device is configured to determine, based on the channel status information and the channel mapping information, whether one or more error conditions are present in the set of LED channels.
