== How to use 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:
*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 == How to use serial console ==[[Image:Igepv2expdb9connector.PNG|right|200px]] IGEPv2 Expansion integrates a DB9 RS232 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 RS232 comunications you should disable RS485 interface. You can do this [[How_do_I_edit_my_kernel_command_line | adding following kernel cmdline parameter]]. board.ei485=no You need a Null-Modem DB9 male-make serial cable. Connect the cable between the target board and reboot your IGEP Device PC. Open the serial port on your PC using your preferred serial communications program (minicom) and configure the port as follows: * 115200* 8N1* no flow control (either software or hardware) 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 finish it.<br>use UARTs]]
== How to use Telit Modem ==
buddy.modem=yes *Power up the modem using the next commands:<pre>$ echo 0 > /sys/class/gpio/gpio140/value$ echo 1 > /sys/class/gpio/gpio141/value$ sleep 1$ echo 0 > /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= How <PIN></pre> *If you correctly inserted the PIN number, the answer should be OK. 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 TVP5151 Video Decoder the GSM/GPS modem.<br> ==''(from From [[How to setup tvp5151 video decoderuse Telit Modem]])'' == How to use TVP5151 Video Decoder ==[[Image:Igepv2expvideocompositeconnector.PNG|right|200px]]IGEPv2 Expansion integrates two composite video connectors to decode analog input signal.

== How to use CAN bus ==
[[Image:Igepv2expcanconnector.PNG|right|200px]]IGEPv2 Expansion integrates a CAN peripheral. Connect any CAN bus device or network to the CAN bus connector (J703). You have to connect the two boards like this:<br> IGEPv2 Exp 1 IGEPv2 Exp 2 .--- .--- | 1 |-X X-| 1 | VDD_CAN: Supply Voltage (+5V DC) | 2 |------------------| 2 | CANL: CAN Low-Level Voltage I/O | 3 |------------------| 3 | GND : Ground | 4 |------------------| 4 | CANH : CAN High-Level Voltage I/O .--- .--- If this is your first time accessing CAN bus, check J702 jumper is not connected before follow this tutorial. If you don't have this jumper, don't worry because its function is only for testing. Now you can set up the interface (from on all boards when using multiple IGEPv2 EXPANSION <span lang="en" id="result_box" class="short_text"><span title="Click for alternate translations" class="hps">connected to a CAN network simultaneously)</span></span>:<br> $ ip link set can0 up type can bitrate 125000 If you want to receive CAN data, use: $ candump can0 If you want to send CAN data, use: $ cansend can0 -i 0x123 0xaa 0xbb 0xcc 0xdd On the receiver side, you must see the following messages: can0 123 [4] aa bb cc dd Switch roles and try it again.
