In this second chapter, we will learn some basics tasks. Upon completion, you will be ready to continue with chapter 3/3 that explains more advanced tasks.

= What can I do =
A detailed guide on how use GPIO-LEDS can be found by following this link: [[How to handle the gpio-LED]]
== Handle generic GPIO ==
See [[How_to_use_GPIOs|GPIOs HOWTO]] to know details about that.
Quick example could be:
<pre>echo 156 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio156/direction
echo 0 > /sys/class/gpio/gpio156/value</pre>
<pre>echo 157 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio157/direction
cat /sys/class/gpio/gpio157/value</pre>
== How to use UART1 (RS232) ==
On the target board open a serial port as follows:
$ microcom -s 115200 /dev/ttyS0
Now when you write a character in you PC serial port, the character should appear in the target board.

A detailed guide on how use UARTS can be found by following this link: [[How to use RS485]]
External Audio input devices, such as a powered microphone or the audio output of a PC or MP3 player, can be connected to the via a 3.5mm jack (Audio IN).
Note that the board has been designed to use Line In for the audio input which means users need to add some type of pre-amp for a microphone to work or use a powered microphone. For a pre-amp for a microphone you can use MAX9812.
Enable capture:
<pre>amixer -c 0 sset 'Analog Right AUXR' cap
amixer -c 0 sset 'Analog Left AUXL' cap </pre>
You can record audio in with the application arecord, for example:
Following output is expected on console:
$ aplay audio-in.wav
== How to change the monitor resolution use wifi == If you have a wireless network adapter in your computer you can also connect to the board using the ad hoc network connection that the firmware configures byu default. Use your wireless manager to connect to the wireless network called in the form IGEP_xx After connecting, a DHCP IP address should be adquired. Now you can access, for example with ssh, to the target board connecting to the 192.168.7.1 address. $ ssh root@192.168.6.1
== How to use bluetooth ==
== How to use the SD card ==
You can connect a micro SD card for storage. After plugin the SD card the kernel should detect the card and automount in /media directory.
== How to use the USB OTG ==
