| − | This How-To is meant to be a starting point for people to learn use SPI for IGEP devices as quickly and easily as possible. In this how-to, we run an example program that reads and writes registers from 3-axis accelerometer ([http://www.st.com/internet/analog/product/250725.jsp LIS3DH]) included on the board IGEP New York. <br>

| − | == Prepare Micro SD Card ==
| + | - Compiled gst-plugins-ugly using yocto tools |
| | | | |
| − | === Generate Micro SD Card (correct) ===
| + | - rpm -igst-plugins-ugly-0.*.rpm |
| | | | |
| − | Open a terminal and use the following steps to download and generate a Micro SD card.
| + | - rpm -i libmad0-0.*.rpm |
| − | <pre>wget http://downloads.isee.biz/denzil/binary/igep_firmware-yocto-1.2.1-1.tar.bz2
| |
| − | tar jxf igep_firmware-yocto-*.tar.bz2
| |
| − | cd igep_firmware-yocto-* </pre>
| |
| − | Insert a SD-Card media and use the igep-media-create script to copy the firmware.
| |
| | | | |
| − | ./igep-media-create -–mmc <mmc> --image demo-image-sato-igep00x0.tar.bz2 --machine igep0030
| + | - rpm -i gst-plugins-ugly-mad-0.*.rpm |
| | | | |
| − | where <mmc> - is the SD-Card device of your computer. For example, assuming the SD-card device takes '/dev/sdb' type:
| + | - gst-launch filesrc location=sample.mp3 ! mad ! volume volume=0.25 ! alsasink |
| − | <pre>./igep-media-create --mmc /dev/sdb --machine igep0030 --image demo-image-sato-igep00x0.tar.bz2 </pre>
| |
| − | This should give you a bootable SD-card with IGEP COM MODULE support.

| | + | libgstsdp-0.10-0 |
| | + | libgstsdp-0.10.so.0 |
| | | | |
| − | To read accelerometer registers from spidev, we need to attach spidev driver to spi driver at start up. So it is necessary to modify spi_board.

| − | === Overview ===
| |
| − | | |
| − | This program is based in [http://git.isee.biz/?p=pub/scm/linux-omap-2.6.git;a=blob;f=Documentation/spi/spidev_test.c;h=16feda9014692a87a4996bf51d759ab9e7500ee5;hb=refs/heads/linux-2.6.37.y spidev_test] and it was edited to run with LIS3DH accelerometer, program can be explained in four parts:
| |
| − | | |
| − | '''Connection properties:''' program lets change via parameters SPI configurations like: device, max speed, delay, bits per word, clock phase, clock polarity, etc. If you don't use any of this parameters program will use default options for LIS3DH communication.
| |
| − | | |
| − | '''Read mode: '''Reads a word from a register.
| |
| − | | |
| − | '''Write mode: '''Writes a word in a register.
| |
| − | | |
| − | '''Test mode:''' Reads X, Y and Z axes from accelerometer.
| |
| − | | |
| − | We recommend to read peripheral datasheet before use or modify program.
| |
| − | | |
| − | === Compile program ===
| |
| − | | |
| − | The program source was compiled with Poky SDK but you can use other compilers like Linaro Toolchain:
| |
| − | <pre>arm-poky-linux-gnueabi-gcc spiexamplebeta2.c -o spiexampleb2 </pre>
| |
| − | Copy your final binary to rootfs.
| |
| − | | |
| − | == Test program<br> ==
| |
| − | | |
| − | === Read WHO_AM_I register(0Fh) ===
| |
| − | | |
| − | LIS3DH has this dummy register (See 8.6 chapter) as a device identification. Its value is 0x33:
| |
| − | <pre>root@igep00x0:~# ./spiexampleb2 -R 0F
| |
| − | spi mode: 0
| |
| − | bits per word: 8
| |
| − | max speed: 1000000 Hz (1000 KHz)
| |
| − | Value from 0F is: 33
| |
| − | root@igep00x0:~# </pre>
| |
| − | === Read and Write CTRL_REG1 (20h) ===
| |
| − | | |
| − | This register is used to enable/disable: accelerometer and XYZ axes (See 8.8 chapter). The default value at startup is:
| |
| − | <pre>root@igep00x0:~# ./spiexampleb2 -R 20
| |
| − | spi mode: 0
| |
| − | bits per word: 8
| |
| − | max speed: 1000000 Hz (1000 KHz)
| |
| − | Value from 20 is: 07
| |
| − | root@igep00x0:~# </pre>
| |
| − | It means that accelerometer was disabled and X, Y and Z axes was enabled. For example we can disable X axe typing:
| |
| − | <pre>root@igep00x0:~# ./spiexampleb2 -W 20 -V 06
| |
| − | spi mode: 0
| |
| − | bits per word: 8
| |
| − | max speed: 1000000 Hz (1000 KHz)
| |
| − | Register to write 20 with value 06
| |
| − | root@igep00x0:~# ./spiexampleb2 -R 20
| |
| − | spi mode: 0
| |
| − | bits per word: 8
| |
| − | max speed: 1000000 Hz (1000 KHz)
| |
| − | Value from 20 is: 06
| |

| |
| − | | |
| − | == SPI Test program ==
| |
| − | | |
| − | === Overview ===
| |
| − | | |
| − | This program is based in [http://git.isee.biz/?p=pub/scm/linux-omap-2.6.git;a=blob;f=Documentation/spi/spidev_test.c;h=16feda9014692a87a4996bf51d759ab9e7500ee5;hb=refs/heads/linux-2.6.37.y spidev_test] and it was edited to run with LIS3DH accelerometer, program can be explained in four parts:
| |
| − | | |
| − | '''Connection properties:''' program lets change via parameters SPI configurations like: device, max speed, delay, bits per word, clock phase, clock polarity, etc. If you don't use any of this parameters program will use default options for LIS3DH communication.
| |
| − | | |
| − | '''Read mode: '''Reads a word from a register.
| |
| − | | |
| − | '''Write mode: '''Writes a word in a register.
| |
| − | | |
| − | '''Test mode:''' Reads X, Y and Z axes from accelerometer.
| |
| − | | |
| − | We recommend to read peripheral datasheet before use or modify program.
| |
| − | | |
| − | === Compile program ===
| |
| − | | |
| − | The program source was compiled with Poky SDK but you can use other compilers like Linaro Toolchain:
| |
| − | <pre>arm-poky-linux-gnueabi-gcc spiexamplebeta2.c -o spiexampleb2 </pre>
| |
| − | Copy your final binary to rootfs.
| |
| − | | |
| − | == Test program<br> ==
| |
| − | | |
| − | === Read WHO_AM_I register(0Fh) ===
| |
| − | | |
| − | LIS3DH has this dummy register (See 8.6 chapter) as a device identification. Its value is 0x33:
| |
| − | <pre>root@igep00x0:~# ./spiexampleb2 -R 0F
| |
| − | spi mode: 0
| |
| − | bits per word: 8
| |
| − | max speed: 1000000 Hz (1000 KHz)
| |
| − | Value from 0F is: 33
| |
| − | root@igep00x0:~# </pre>
| |
| − | === Read and Write CTRL_REG1 (20h) ===
| |
| − | | |
| − | This register is used to enable/disable: accelerometer and XYZ axes (See 8.8 chapter). The default value at startup is:
| |
| − | <pre>root@igep00x0:~# ./spiexampleb2 -R 20
| |
| − | spi mode: 0
| |
| − | bits per word: 8
| |
| − | max speed: 1000000 Hz (1000 KHz)
| |
| − | Value from 20 is: 07
| |
| − | root@igep00x0:~# </pre>
| |
| − | It means that accelerometer was disabled and X, Y and Z axes was enabled. For example we can disable X axe typing:
| |
| − | <pre>root@igep00x0:~# ./spiexampleb2 -W 20 -V 06
| |
| − | spi mode: 0
| |
| − | bits per word: 8
| |
| − | max speed: 1000000 Hz (1000 KHz)
| |
| − | Register to write 20 with value 06
| |
| − | root@igep00x0:~# ./spiexampleb2 -R 20
| |
| − | spi mode: 0
| |
| − | bits per word: 8
| |
| − | max speed: 1000000 Hz (1000 KHz)
| |
| − | Value from 20 is: 06

| |
| − | <pre>ssh root@192.168.5.1
| |
| − | mkdir /tmp/temp
| |
| − | mount -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 to finish it.<br>
| |

| − | == How to use Telit Modem ==
| |
| − | | |
| − | '''Basic'''
| |
| − | | |
| − | Telit modem is not supported by default in IGEPv2. 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 following commands:
| |
| − | <pre>ssh root@192.168.5.1
| |
| − | mkdir /tmp/temp
| |
| − | mount -t jffs2 /dev/mtdblock1 /tmp/temp
| |
| − | vi /tmp/temp/igep.ini </pre>
| |
| − | *Add the following line (press i to insert content):
| |
| − | | |
| − | buddy.modem=yes
| |
| − | | |
| − | *Save changes (ESC -> :wq -> Enter) and reboot your IGEP Device
| |
| − | *Power up the modem. You can power off using again these 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 D401, near SIM card reader, 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=<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 the GSM/GPS modem.<br>
| |
| − | | |
| − | === Examples ===
| |
| − | | |
| − | If you successfully '''followed the the previous instructions''', you are ready to test the GSM/GPRS modem. Here are some examples:
| |
| − | | |
| − | You can check the complete list of AT commands at the Official manufacturer [http://telit.com/module/infopool/download.php?id=522 Software User Guide].
| |
| − | | |
| − | ==== Test received signal strength<br> ====
| |
| − | | |
| − | Use the instruction:
| |
| − | <pre>at+csq</pre>
| |
| − | The answer should be: +CSQ: X,0, where X is the signal strenght. For example 12 is poor and 18 is good. If the answer is +CSQ:99,99 you should check your coverage or use an antenna<br>
| |
| − | | |
| − | ==== Making a phone call<br> ====
| |
| − | | |
| − | Use the instruction, replace number_to_call with your number:
| |
| − | <pre>atd number_to_call
| |
| − | </pre>
| |
| − | Press any key to end call
| |
| − | | |
| − | '''NOTE:''' If "NO CARRIER" message appears, check your coverage or use an antenna.
| |
| − | | |
| − | ==== Sending a SMS<br> ====
| |
| − | | |
| − | First of all, you need to configure the SMS format type. Telit GE865 GSM/GPRS supports 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, replace destination_number with your number:
| |
| − | <pre>at+cmgs= destination_number
| |
| − | > insert here your text message
| |
| − | </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>
| |
| − | | |
| − | '''NOTE:''' If "NO CARRIER" message appears, check your coverage or use an antenna.
| |
| − | | |
| − | '''NOTE:''' Don't use special characters in SMS text message like <`´'">.<br>

| − | == How to use TVP5151 Video Decoder <br> ==
| |
| − | | |
| − | '''Basic'''
| |
| − | | |
| − | Use the following steps to capture analog video:
| |
| − | | |
| − | *Connect a video composite input to J501 connector from IGEPv2 Expansion (near CAN Bus)
| |
| − | *Connect a screen, for example HDMI monitor.
| |
| − | *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 following commands:
| |
| − | <pre>ssh root@192.168.5.1
| |
| − | </pre>
| |
| − | *Now you have a remote igep terminal<br>
| |
| − | *Refresh repositories and accept it.
| |
| − | <pre>zypper ref </pre>
| |
| − | *Install video4linux2 plugin
| |
| − | <pre>zypper in gst-plugins-good-video4linux2
| |
| − | </pre>
| |
| − | *Load OMAP ISP kernel module<br>
| |
| − | <pre>modprobe omap3-isp
| |
| − | </pre>
| |
| − | *Configure ISP, for PAL resulution use 720x576 for NTSC resolution use 720x480:<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]'
| |
| − | 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=:0.0 </pre>
| |
| − | *Launch gstreamer
| |
| − | <pre>gst-launch-0.10 -v v4l2src device=/dev/video2 queue-size=8 ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=720,height=480 ! ffmpegcolorspace ! autovideosink</pre>
| |
| − | *Now you can see in your IGEP screen a result similar like this

| − | == How to use EEPROM ==
| |
| − |
| |
| − | '''Basic'''
| |
| − |
| |
| − | The IGEP0022 expansion board provides an AT24C01B serial EEPROM memory which is connected to the OMAP via I2C (register 50).<br>
| |
| − |
| |
| − | Use i2c-tools to manage it:
| |
| − | <pre>i2cget <bus> <chip> <register>
| |
| − | i2cset <bus> <chip> <register> <value></pre>
| |
| − | For example, the following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:
| |
| − | <pre>i2cset -f -y 2 0x50 0x10 0x22
| |
| − | i2cget -f -y 2 0x50 0x10</pre>

IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)
This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine. Because you use eth0 device to communicate easily with your board and eth0:0 device to get Internet acces using dhcp protocol.
But some scenarios this network configuration is not useful, for example: if you use a non-Linux operating system, connect to two IP private range interfaces is not simple. This How-to can be useful to
(Make diagram one: IGEP and Linux defualt communication. Diagram 2 IGEP and other SO alternative configuration)
The kernel command line syntax is name=value1. These next parameters are supported in igep.ini since IGEP-X_Loader 2.4.0-2:
