You want to set timer trigger (first turn it on in the config):

echo "timer" > trigger

After that two files appear: delay_on and delay_off.

ledtrig-timer uses blink_set op for setting up the hw blinking.

Thank you for explanation.

I just want to clerify - for now LEDs board has 2 from 3 LEDs with effect function.

1. Screen frame led is just blinking, so blink_set() is fit well to this.
2. Pipe led actually consist from 3 leds and when effect is enabled next pattern is used:

       ^

LED1  >   OFF  ON   ON   ON

LED2  >   OFF  OFF  ON   ON
       |
LED3  >   OFF  OFF  OFF  ON
       |
       +----^----^----^----^----> time

Pattern trigger applies to a single LED so it won't fit for this
pattern.

Currently we don't support patterns spanning on multiple LEDs,
so you would have to come up with your own solution.

What I can recommend is a trigger that would be created by your driver
and would activate this sequence.
