| D | leds-lm3556.rst | 16 There are 3 functions in LM3556, Flash, Torch and Indicator.
47 Torch Mode
50 In Torch Mode, the current source(LED) is programmed via the CURRENT CONTROL
51 REGISTER(0x09).Torch Mode is activated by the ENABLE REGISTER(0x0A) or by the
52 hardware TORCH input.
54 LM3556 torch can be controlled through sys/class/leds/torch/brightness file.
55 * if TORCH pin is enabled, below example control brightness only,
56 and ON / OFF will be controlled by TORCH pin.
58 Torch Example:
62 #echo 0 > sys/class/leds/torch/brightness
