→IGEP COM MODULE Board
Now the selected led is configured with a timer consisting of 250 miliseconds ON and 750 miliseconds OFF.

''' Basic '''
Log into IGEP COM MODULE (for example via SSH, as shown in the previous chapter), and run the following commands to turn LED's on:
<pre>echo 1 > /sys/devices/platform/leds-gpio/leds/d242\:green/brightness
echo 1 > /sys/devices/platform/leds-gpio/leds/d441\:green/brightness
echo 1 > /sys/devices/platform/leds-gpio/leds/d442\:green/brightness</pre>
You can turn them down using the same command and write '0' instead of '1'.
''' Know more '''
IGEP COM PROTON LED's are controlled with it's platform device at /sys/devices/platform/leds-gpio/leds/
If you want to trigger the leds you can enable this mode and select the trigger source (none by default) to: mmc0, mmc1, timer, heartbeat and default-on.<br>
To enable any of this modes you just have to change a parameter in the directory of the led you want to control. You can see all the possibilities using the instruction 'cat':<br>
<pre>$ cat /sys/devices/platform/leds-gpio/leds/d242\:green/trigger
[none] mmc0 mmc1 timer heartbeat default-on
</pre>
In the example above, we have checked the status of the trigger in led d242:green. Mode 'none' is selected.
To change it, for example, to the ''timer'' mode you can use 'echo':
<pre>echo timer > /sys/devices/platform/leds-gpio/leds/d242\:green/trigger
</pre>
In this case, we have set the trigger to the 'timer' mode. Now you can set the time for what the led is ON and the time it is OFF using:
<pre>echo 250 > /sys/devices/platform/leds-gpio/leds/d242\:green/delay_on
echo 750 > /sys/devices/platform/leds-gpio/leds/d242\:green/delay_off
</pre>
Now the selected led is configured with a timer consisting of 250 miliseconds ON and 750 miliseconds OFF.
