= How to enable IGEP0022 support =
The required [[How do I edit my kernel command line | kernel command line]] option here is
buddy=igep0022
= Getting 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.
= Using 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"
Section "ServerLayout"
# InputDevice "Configured Mouse"
EndSection
calibrate it yourself until you are happy with the result, for example:
/etc/init.d/xserver-nodm stop
sleep 1
echo 0 > /sys/class/gpio/gpio141/value # Sets to '1' the modem On_Off pin</pre>
=== Setting up<br> ===
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 # GE865 has auto baud rate detection, so you can use a different speed
</pre> = Using TVP5151 Video Decoder =
= Using 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

= Using CAN bus =
Several tools are provided by socketCAN:
* 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
