Controlling the LEDS
The LEDs offer two different types of control. The first is basic on/off control which is achieved through the brightness file. The LED can be turned on by writing positive value to the brightness file. To turn the LED off, a zero may be written.
For example, to turn on the D9 led, the following command could be used.
echo 1 > /sys/class/leds/no_inet/brightness
To turn off the D9 led, the following command could be used.
echo 0 > /sys/class/leds/no_inet/brightness
For more advanced control, the led may be set to trigger based on events. There are a variety of different event types which are available on the system.
