| − | = How to handle the LED's<br> =
| |
| − | | |
| − | This is probably the most simple feature in the board, but sometimes LED's may be the only way of checking the status of some of your applications.
| |
| − | | |
| − | IGEP0020 has 4 LED's which you can control, for example, using 'echo'. Here is an example of turning LED's On:
| |
| − | <pre>echo 1 > /sys/devices/platform/leds-gpio/leds/d240\:green/brightness
| |
| − | echo 1 > /sys/devices/platform/leds-gpio/leds/d240\:red/brightness
| |
| − | echo 1 > /sys/devices/platform/leds-gpio/leds/d440\:green/brightness
| |
| − | echo 1 > /sys/devices/platform/leds-gpio/leds/d440\:red/brightness
| |
| − | </pre>
| |
| − | You can turn them down using the same command and write '0' instead of '1'.
| |
| − | | |
| − | 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 'cat':<br>
| |
| − | <pre>$ cat /sys/devices/platform/leds-gpio/leds/d240\:green/trigger
| |
| − | | |
| − | [none] mmc0 mmc1 timer heartbeat default-on
| |
| − | </pre>
| |
| − | In the example above, we have checked the status of the trigger in led D240:green. Mode 'none' is selected.
| |
| − | | |
| − | To change it, for example, to the timer mode you can use 'echo':<br>
| |
| − | <pre>echo timer > /sys/devices/platform/leds-gpio/leds/d240\: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:<br>
| |
| − | <pre>echo 250 > /sys/devices/platform/leds-gpio/leds/d240\:green/delay_on
| |
| − | echo 750 > /sys/devices/platform/leds-gpio/leds/d240\:green/delay_off
| |
| − | </pre>
| |
| − | Now the selected led is configured with a timer consisting of 250 miliseconds ON and 750 miliseconds OFF.<br>
