LP5523 has the internal program memory for running various LED patterns.
-For the details, please refer to 'firmware' section in leds-lp55xx.txt
+There are two ways to run LED patterns.
+
+1) Legacy interface - enginex_mode, enginex_load and enginex_leds
+ Control interface for the engines:
+ x is 1 .. 3
+ enginex_mode : disabled, load, run
+ enginex_load : microcode load (visible only in load mode)
+ enginex_leds : led mux control (visible only in load mode)
+
+ cd /sys/class/leds/lp5523:channel2/device
+ echo "load" > engine3_mode
+ echo "9d80400004ff05ff437f0000" > engine3_load
+ echo "111111111" > engine3_leds
+ echo "run" > engine3_mode
+
+ To stop the engine:
+ echo "disabled" > engine3_mode
+
+2) Firmware interface - LP55xx common interface
+ For the details, please refer to 'firmware' section in leds-lp55xx.txt
