of led events.
You can change triggers in a similar manner to the way an IO
scheduler is chosen. Trigger specific parameters can appear in
/sys/class/leds/<led> once a given trigger is selected.
/sys/class/leds/<led> once a given trigger is selected. For
their documentation see sysfs-class-led-trigger-*.

What: /sys/class/leds/<led>/delay_on
Date: Jun 2012

Description:
Specifies for how many milliseconds the LED has to stay at
LED_FULL brightness after it has been armed.
Defaults to 100 ms.

Description:
Specifies for how many milliseconds the LED has to stay at

Defaults to 100 ms.

Description:
Reverse the blink logic. If set to 0 (default) blink on for
delay_on ms, then blink off for delay_off ms, leaving the LED
normally off. If set to 1, blink off for delay_off ms, then
blink on for delay_on ms, leaving the LED normally on.
Setting this value also immediately changes the LED state.

Description:
Write any non-empty string to signal an events, this starts a
blink sequence if not already running.
