VIM1/2

VIM1/VIM2 has only one node.

$ ls /sys/class/leds
sys_led

VIM3/3L

VIM3/VIM3L has two nodes.

$ ls /sys/class/leds
red_led  sys_led

VIM4

VIM4 has only one node which is a PWM LED.

$ ls /sys/class/leds
pwmled

Edge1

Edge1 has two nodes.

$ ls /sys/class/leds
read_led  sys_led

Edge2

VIM1/2/3/3L

We will take sys_led (white) as an example.

Turn off

Set the LED node parameter to none to turn off the LED:

$ echo none | sudo tee /sys/class/leds/sys_led/trigger

Turn on

Set the LED node parameter to default-on to keep the LED permanently on:

$ echo default-on | sudo tee /sys/class/leds/sys_led/trigger

Set LED heartbeat

Set the LED node parameter to heartbeat, to make the LED flash with a heartbeat blink:

$ echo heartbeat > /sys/class/leds/sys_led/trigger

You can also try other parameters.

VIM4

We will take pwmled (white) as an example.

Turn off

Set the LED node parameter to none to turn off the LED:

$ echo none | sudo tee /sys/class/leds/pwmled/trigger

Turn on

Set the LED node parameter to default-on, to make the LED permanently on:

$ echo default-on | sudo tee /sys/class/leds/pwmled/trigger

Set LED heartbeat

Set the LED node parameter to heartbeat, to make the LED flash with a heartbeat blink:

$ echo heartbeat > /sys/class/leds/pwmled/trigger

You can also experiment with other parameters.

Edge1

We will use sys_led as an example:

Turn off Set the LED node parameter to none to turn off the LED:

$ echo none | sudo tee /sys/class/leds/sys_led/trigger

Turn on

Set the LED node parameter to default-on to keep the LED permanently on:

$ echo default-on | sudo tee /sys/class/leds/sys_led/trigger

Set LED heartbeat

Set the LED node parameter to heartbeat, to make the LED flash with a heartbeat blink:

$ echo heartbeat > /sys/class/leds/sys_led/trigger

You can also experiment with other parameters.
