More details of the instructions can be found from the public data sheet.



LP5521 has the internal program memory for running various LED patterns.

There are two ways to run LED patterns.



1) Legacy interface - enginex_mode and enginex_load

  Control interface for the engines:

  x is 1 .. 3

  enginex_mode : disabled, load, run

  enginex_load : store program (visible only in engine load mode)



  Example (start to blink the channel 2 led):

  cd   /sys/class/leds/lp5521:channel2/device

  echo "load" > engine3_mode

  echo "037f4d0003ff6000" > engine3_load

  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



sysfs contains a selftest entry.
