Claim 19:
20. A light-emitting diode (LED) driver system comprising:
a master computing device;
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; and
a core computing device configured to:
receive, from the master computing device, LED control information including a desired output for each LED of the set of LEDs;
generate, based on the LED control information, primary path LED driver control output data;
generate, based on the LED control information, secondary path LED driver control output data;
compare the primary path LED driver control output data with the secondary path LED driver control output data to detect whether one or more error conditions are present in the core computing device;
output the primary path LED driver control output to the set of LED drivers to control the set of LED drivers to achieve the desired output for each LED of the set of LEDs;
receive channel status feedback information that indicates an output of each LED of the set of LEDs;
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 in the core computing device, in the set of LED drivers, or in the set of LEDs, one or more remedial actions for controlling the set of LED drivers to remedy the one or more error conditions.
