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.
