If you have '''successfully completed the [[Getting Started with IGEP0022 board|getting started guide]]''' for IGEP0022, you can follow this first introduction about what can you do with this expansion board:  = How to use Serial communication =Please contribute .. = How to get VGA output = The required [[How do I edit my kernel command line|kernel command line]] option here is omapfb.mode followed by the desired resolution, make sure to select a video mode compatible with your monitor  For example:   omapdss.def_disp=dvi omapfb.mode=dvi:1024x768-16@60 Note that you could connect both a VGA monitor and a DVI-D monitor and see the same image, as long as the video mode is compatible with both monitors.  = How to use TFT and Touchscreen = Seiko 7.0 inch WVGA (800 x RGB x 480) TFT:   omapdss.def_disp=lcd-70 Powertip 4.3 inch (480 x RGB x 272) TFT:   omapdss.def_disp=lcd-43 To configure the touchscreen, add "Configured Touchscreen" in "ServerLayout" section and remove "Configured Mouse" in /etc/X11/xorg.conf  Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" InputDevice "Generic Keyboard" # InputDevice "Configured Mouse" InputDevice "Configured Touchscreen" Option "AllowEmptyInput" "no" EndSection calibrate it yourself until you are happy with the result, for example:   /etc/init.d/xserver-nodm stop TSLIB_CALIBFILE=/etc/pointercal TSLIB_TSDEVICE=/dev/input/touchscreen0 TSLIB_CONSOLEDEVICE=none ts_calibrate /etc/init.d/xserver-nodm start = How to use Telit Modem = The IGEP0022 expansion board provides a Telit [http://telit.com/en/products/gsm-gprs.php?p_ac=show&p=47 GE865] GSM/GPRS&nbsp;modem which is connected to the OMAP via some GPIO pins and UART 2.<br>  Here you have the official manuals from the manufacturer's webpageREDIRECT:<br>  *[http://telit.com/module/infopool/download.php?id=1666 Telit GE865-QUAD Hardware User Guide]<br> *[http://telit.com/module/infopool/download.php?id=522 Telit Modules Software User Guide]<br> <br>  Here there are a few instructions in order to introduce the Telit modem.<br>  If this is your first time accessing Telit Modem, you must add the following line at the kernel file (igep.ini) in order to enable GE865 support&nbsp;: <pre>buddy.modem=yes</pre> <br>  Now its time to power up your modem. You may read the Official manufacturer [http://telit.com/module/infopool/download.php?id=1666 Hardware User Guide], where there is a complete explanation about the sequence.<br>  In IGEP0022, the modem is connected to 3 GPIO pins from the OMAP, which are: &lt;omap_pin_name (modem_function)&gt;  *GPIO_140 (Reset) *GPIO_141 (On_Off) *GPIO_156 (PWRMON)<br> You What can power up your modem using the following sequence:  (Note: the following instructions are correctly 'toggled' I do to pull-up resistors.

You can use Microcom to comunicate with it from the serial debug console: <pre>microcom -s 115200 /dev/ttyS1</pre> (Note:&nbsp;GE865 has auto baud rate detection, so you can use a different speed)<br>  To check the modem status use the command:<br> <pre>at</pre> Answer should be OK.<br>  (Note: correcting syntax with 'backspace' may cause error in a serial command if you are not writing the command at first take)  In order to use your GSM/GPRS you should connect the antenna as it is explained in the [[Getting Started with IGEP0022 board#GSM/GPRS antenna |Getting Started with IGEP0022]] article.  Then you can insert a valid SIM card to the SIM card reader of your IGEP0022 expansion board.  Now unlock it by inserting your SIM&nbsp;card PIN&nbsp;number. Use the command:<br> <pre>at+cpin=&lt;PIN&gt;</pre> If you correctly inserted the PIN&nbsp;number, the answer should be OK.  (Note: If you fail more than 3 times, your SIM&nbsp;card will lock and you will have to insert PUK number.)  Now you are ready to use the GSM/GPS modem.  == Examples == If you successfully '''followed the the previous instructions''', you are ready to test the GSM/GPRS&nbsp;modem. Here are some examples of simple&nbsp;commands:  You can check the complete list of AT&nbsp;commands at the Official manufacturer [http://telit.com/module/infopool/download.php?id=522 Software User Guide].  === Making a phone call<br> === Use the instruction: <pre>atd &lt;number_to_call&gt;</pre> === Sending a SMS<br> === There are so many ways in this modem to send a message. Here you have a simple example. Use the instruction: <pre>at+cmgs="&lt;destination_number&gt;"&gt; &lt;insert_here_your_text_message&gt;</pre> When you are ready to send your message use Ctrl+Z to send it.  If you want to cancel or restart the message press ESC.<br> = How to use TVP5151 Video Decoder<br> = === Requirements<br> === *Have successfully connected the TFT Screen as explained at the [[Getting Started with IGEP0022 board#TFT_and_Touchscreen|Getting Started Guide]] or at the [http://igep.es/index.php?option=com_content&view=article&id=99&Itemid=129&dir=%2Fvar%2Fwww%2Fvhosts%2Figep.es%2Fhttpdocs%2Fdownloads%2F01-ISEE_Products%2FIGEPv2_EXPANSION%2FHW_User_Manuals&download_file=%2Fvar%2Fwww%2Fvhosts%2Figep.es%2Fhttpdocs%2Fdownloads%2F01-ISEE_Products%2FIGEPv2_EXPANSION%2FHW_User_Manuals%2FMAN-PR-IGEP.0022-001.01.HW_USER_MANUAL.pdf Official Hardware Reference Manual]<br> *A camera or any device with PAL output video to RCA&nbsp;connector.<br> <br>  ---- <br>  There are two modules that you will use that are not inserted into the kernel: iommu2 (tvp5151) and isp.  You have to load these kernel modules before start:<br> <pre>modprobe iommu2modprobe omap3-isp</pre> (Note: The first load order must be the iommu2 and then the omap3-isp)<br>  ---- <br>  Now, use the program media-ctl. This program is useful to configure the ISP. You can download it from [http://downloads.igep.es/files/media-ctl here]. Then you have to transfer it to your IGEP0022 (for example via SCP command).<br>  Now you have to configure the ISP and TVP5151:<br> <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]'</pre> Configure the video capture setup:<br> <pre>./media-ctl --set-format '"tvp5150 2-005c":0 [UYVY 720x628]'</pre> Connect a video camera or any device with PAL&nbsp;output to the Composite Video RCA input connector of the IGEP0022.  Use gstreamer as live stream to capture video from your video source.<br>  Now setup the gstreamer pipeline:<br> <pre>gst-launch-0.10 -v v4l2src device=/dev/video2 queue-size=1&nbsp;! video/x-raw-yuv,format=\(fourcc\)UYVY,width=720,height=628&nbsp;! omapfbsink</pre> If everything was fine you will see the live video at the screen.  [[Image:TVP5151 video decoder.jpg|frame|center|514x346px]]See also: [[How to setup tvp5151 video decoder]]<br> = How to use EEPROM = The IGEP0022 expansion board provides an [http://www.atmel.com/dyn/resources/prod_documents/doc5156.pdf AT24C01B] serial EEPROM memory which is connected to the OMAP via I2C.<br>  You can use easily simple reads/writes to access to the eeprom:   echo "hello world!" &gt; /sys/devices/platform/i2c_omap.2/i2c-2/2-0050/eeprom cat /sys/devices/platform/i2c_omap.2/i2c-2/2-0050/eeprom Or read/write from userspace using i2c-tools:   i2cget &lt;bus&gt; &lt;chip&gt; &lt;register&gt; i2cset &lt;bus&gt; &lt;chip&gt; &lt;register&gt; &lt;value&gt; For example, the following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:   i2cset -f -y 2 0x50 0x10 0x22 i2cget -f -y 2 0x50 0x10 See also: i2dump(8), i2cget(8) and i2cset(8) man page  = How to use CAN bus = The IGEP0022 expansion board provides a CAN&nbsp;interface using MCP2515.<br>  Several tools are provided by socketCAN to use this controller:  *candump: dump traffic on a CAN network. *cansend: simple command line tool to send CAN-frames via CAN_RAW sockets. *cangen: CAN frames generator for testing purpose. *canplayer: send CAN frames from a file to a CAN interface. In order to test the CAN&nbsp;interface you can connect IGEP0022 to a CAN device or network or to another IGEP0022 board.<br>  In the last case, you have to connect the two boards like this:<br>   Board 1 Board 2 .--- --- | 1 |-X X-| 1 | | 2 |----------------| 2 | | 3 |----------------| 3 | | 4 |----------------| 4 | .--- --- Now you can set up the interface (on all boards when using multiple IGEP0022 <span lang="en" id="result_box" class="short_text"><span title="Click for alternate translations" class="hps">connected to a CAN&nbsp;network simultaneously)</span></span>:<br>   /sbin/ip link set can0 up type can bitrate 125000 If you want to receive CAN&nbsp;data, use:   candump can0 If you want to send CAN data, use:   cansend can0 123#AABBCCDD cansend can0 123#R cansend can0 1F334455#1122334455667788 cansend can0 1F334455#R On the receiver side, you must see the following messages:   can0 123 [4] AA BB CC DD can0 123 [0] remote request can0 1F334455 [8] 11 22 33 44 55 66 77 88 can0 1F334455 [0] remote request Switch roles and try it again [[Category:IGEP0022]][[Category:TutorialsIGEPv2 EXPANSION]]
