This is the 2/3 chapter of IGEPv2 Expansion Tutorial Guide.
We will learn some basic tasks such add support to IGEPv2 Expansion, control some peripherals, etc.<br>   __TOC__  
= What can I do<br> =
== How to use Serial communication (DB9 connector) TFT and Touchscreen ==[[Image:IGEP0022 PROTO RA DSC 0142.JPG|right|200px]] IGEPv2 Expansion supports SEIKO 7” or POWERTIP 4.3” LCD screen. Use J301 connector for POWERTRIP 4.3" or use J302, J303 and J304 connector for SEIKO 7".<br> Seiko and Powertip touch screens are not supported by default in IGEPv2. Use the following steps for it:
'''Basic''' Edit igep.ini file to configure your touch screen, you can do this [[How_do_I_edit_my_kernel_command_line | adding following kernel cmdline parameter]]*In Seiko screen add the following line:<pre>omapdss.def_disp=lcd-70</pre> *In Powertip screen add the following line:<pre>omapdss.def_disp=lcd-43</pre>
== How to use serial console ==[[Image:Igepv2expdb9connector.PNG|right|200px]] IGEPv2 Expansion integrates a DB9 RS232 link connector. This UART is shared with RS485 so it's incompatible use both interfaces at the same time. For that reason to use UART1 for UART 3 (/dev/ttyO2) can be obtained through J502 DB9 connectorRS232 comunications you should disable RS485 interface. You can use PuTTy to get a shell prompt to IGEP: do this [[How_do_I_edit_my_kernel_command_line | adding following kernel cmdline parameter]].
*Power up IGEPv2 *Open PuTTy. *Choose Serial line. If you are running PuTTy on Windows, the Serial line will be like (COM1 or COM2 or COM3, etc.). If you are running PuTTy on Ubuntu, the Serial line will be like&nbsp;(/dev/ttyS0 or /dev/ttyS1 or /dev/ttyS3, etc.). Note that if you are using a USB-&gt;Serial converter, the Serial line will be like /dev/ttyUSB0 *Configure Speed to 115200 *Select Serial Connection type *Press on Open button *You will successfully started the console board.ei485=no
<br> You need a Null-Modem DB9 male-make serial cable. Connect the cable between the target board and your PC.

[[How to use UARTs|Read this tutorial]] to learn about UARTs. On the target board open a serial port as follows:
== How to use TFT and Touchscreen == $ microcom -s 115200 /dev/ttyS0
Seiko and Powertip touch screens are not supported by default Now when you write a character in IGEPv2you PC serial port, the character should appear in the target board. Use the following steps for it:
*Log into IGEPv2 (via SSH, [http://labs.isee.biz/index.php/Getting_started_with_IGEPv2#Log_into_IGEPv2_via_Ethernet_interface as shown in the previous chapter]), and run the A detailed guide on how use UARTS can be found by following commandsthis link:<pre>ssh root@192.168.5.1 mkdir /tmp/tempmount -t jffs2 /dev/mtdblock1 /tmp/temp vi /tmp/temp/igep.ini </pre> *In Seiko screen add the following line:<pre>omapdss.def_disp=lcd-70</pre> *In Powertip screen add the following line:<pre>omapdss.def_disp=lcd-43</pre> *Save changes and reboot your IGEP Device [[How to finish it.<br>use UARTs]]

== How to use TVP5151 Video Decoder *Power up the modem using the next commands:<brpre> ==$ echo 0 &gt; /sys/class/gpio/gpio140/value$ echo 1 &gt; /sys/class/gpio/gpio141/value$ sleep 1$ echo 0 &gt; /sys/class/gpio/gpio141/value</pre> *Once the modem is on (led near power button is blinking now), you can interact with it via UART 2.
You can use Microcom to comunicate with it from the serial debug console:
<pre>$ microcom -s 115200 /dev/ttyO1</pre>
*To check the modem status use the command:<br>
<pre>at</pre>
*Answer should be OK.<br>
*Now unlock it by inserting your SIM card PIN number. Use the command:
<pre>at+cpin=&lt;PIN&gt;</pre>
*If you correctly inserted the PIN number, the answer should be OK.&nbsp;If you fail more than 3 times, your SIM card will lock and you will have to insert PUK number.
*Now you are ready to use the GSM/GPS modem.<br>

== How to use TVP5151 Video Decoder ==
[[Image:Igepv2expvideocompositeconnector.PNG|right|200px]]IGEPv2 Expansion integrates two composite video connectors to decode analog input signal.
=== Configure TVP5151 ===
{{#lst*Plug some peripheral with video composite output in J501 RCA connector, see the image for more details.<br> *Connect a screen, for example HDMI monitor. *Refresh repositories and accept it.<pre>$ zypper ref </pre> *Install video4linux2 plugin<pre>$ zypper in gst-plugins-good-video4linux2</pre>=== Play with TVP5151 ===*Load OMAP ISP kernel module<br><pre>$ modprobe omap3-isp</pre> *Configure ISP, for PAL resulution use 720x576 for NTSC resolution use 720x480:<pre>$ media-ctl -r -l '"tvp5150 2-005c":0-&gt;"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1-&gt;"OMAP3 ISP CCDC output":0[1]'$ media-ctl -v --set-format '"tvp5150 2-005c":0 [UYVY 720x480]'$ media-ctl -v --set-format '"OMAP3 ISP CCDC":0 [UYVY 720x480]'$ media-ctl -v --set-format '"OMAP3 ISP CCDC":1 [UYVY 720x480]' </pre> *Export display<pre>$ export DISPLAY=:How to setup tvp5151 0.0 </pre> *Launch gstreamer<pre>$ gst-launch-0.10 -v v4l2src device=/dev/video2 queue-size=8&nbsp;! video decoder|configure}}/x-raw-yuv,format=\(fourcc\)UYVY,width=720,height=480&nbsp;! ffmpegcolorspace&nbsp;! autovideosink</pre> *Now you can see in your IGEP screen a result similar like this

== How to use EEPROM ==
IGEPv2 Expansion includes a serial EEPROM, provides 1KB of user data storage. EEPROM is connected through I2C2 of OMAP3 processor at address 0x50.

{{#lst[[Image:How Igepv2expcanconnector.PNG|right|200px]]IGEPv2 Expansion integrates a CAN peripheral. Connect any CAN bus device or network to use the CAN busconnector (J703). You have to connect the two boards like this:<br>   IGEPv2 Exp 1 IGEPv2 Exp 2 .--- .--- | 1 |-X X-|IGEPv2 EXPANSION}} 1 | VDD_CAN: Supply Voltage (+5V DC){{Template | 2 |------------------| 2 | CANL:NavigationCAN Low-Level Voltage I/IGEP Technology GuidesO | 3 |------------------| 3 | GND : Ground | 4 |------------------| 4 | CANH : CAN High-Level Voltage I/What O .--- .--- If this is your first time accessing CAN bus, check J702 jumper is not connected before follow this tutorial.
