=What can I do == Booting and setting up ===----
In this tutorial, we are going to use the '''4 LED's available in the board''', which probably is the most simple feature in the board, but sometimes you may want LED's to be a way of checking the status of some of your applications.
You can turn them down using the same command and write '0' instead of '1'.
''' Know more '''
IGEPv2 LED's are controlled with it''Boot priority'''s platform device at /sys/devices/platform/leds-gpio/leds/
<pre>$ cat /sys/devices/platform/leds-gpio/leds/d240\:green/trigger
In the example above, we have checked the status of the trigger in led D240:green. Mode 'none' is selected.
<pre>echo timer > /sys/devices/platform/leds-gpio/leds/d240\:green/trigger
</pre>
Now let's transfer a file called original.file in your host PC to IGEPv2 in /home/root/
=== Flashing the Update your pre-installed software image ===----
=== Requirements ===
We are now going to update the pre-installed software to the latest version.
The software provided by ISEE has a script that flashes the content of your MicroSD Card to the flash memory in your IGEPv2. You have to run this script, that is located at /opt/firmware directory.
cd /opt/firmware
reboot
IGEPv2 is '''compatible with many Linux distributions'''. In this tutorial we are using Poky Linux, which is the pre-installed software from ISEE.

umount /mnt/tmp

Follow the link to the extensive article: [[How_to_use_RS485_on_IGEP0020_board|How to use RS-485 on IGEPv2 board]]
You can record audio in with the application Arecord, for example:
When ever you think you want to stop recording just press CTRL+C
== How to get sound out (audio out) ==
''' Basic '''
Connect an '''external output audio device''' to the 3.5mm jack Audio Out connector in IGEPv2, such as external stereo powered speakers.
The amplifiers for the headset output are disabled by default, so the first thing you'll do is enable these amplifiers with:
amixer set -D hw:0 'Headset' 0dB
amixer set -D hw:0 'HeadsetL Mixer AudioL2' on
amixer set -D hw:0 'HeadsetR Mixer AudioR2' on
Then you can easily play a *.wav sound with the application Aplay, for example:
aplay audio-in.wav
