| − | *GPIO_140 (Reset)
| |
| − | *GPIO_141 (On_Off)
| |

| |
| − | sleep 1
| |
| − | echo 0 > /sys/class/gpio/gpio141/value
| |
| − | </pre>
| |
| − | Once the modem is on, 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/ttyS1</pre>
| |
| − | (Note: 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. Don't type <> when use the following commands'''
| |
| − | | |
| − | 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.
| |
| − | | |
| − | Now unlock it by inserting your SIM card PIN number. Use the command:<br>
| |
| − | <pre>at+cpin=<PIN></pre>
| |
| − | If you correctly inserted the PIN number, the answer should be OK.
| |
| − | | |
| − | (Note: If you fail more than 3 times, your SIM card will lock and you will have to insert PUK number.)

| − | === Sending a SMS<br> ===
| |
| − | | |
| − | First of all, you need to configure the SMS format type. Telit [http://telit.com/en/products/gsm-gprs.php?p_ac=show&p=47 GE865] GSM/GPRS support PDU format and Text format. We use Text format. Type the following command:

| − | | |
| − | <pre>AT+CMGF=1</pre>
| |
| − | | |
| − | There are so many ways in this modem to send a message. Here you have a simple example. Use the instruction:
| |
| − | <pre>at+cmgs="<destination_number>"
| |
| − | > <insert_here_your_text_message>
| |

| |
| − | | |
| − | 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 iommu2
| |
| − | modprobe 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->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1->"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 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 ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=720,height=628 ! omapfbsink</pre>
| |
| − | If everything was fine you will see the live video at the screen.

| − | = 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!" > /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 <bus> <chip> <register>
| |
| − | i2cset <bus> <chip> <register> <value>
| |
| − | | |
| − | 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

| |
| − | | |
| − | Check J702 jumper is not connected before follow the tutorial.
| |
| − | | |
| − | The IGEP0022 expansion board provides a CAN 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 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 |

| |
| − | | 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 network simultaneously)</span></span>:<br>
| |
| − | | |
| − | /sbin/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 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
