What can I do with IGEP0022

(work in progress)

Bring up eth0

udhcpc -i eth0

ALSA active the headset path

amixer set -D hw:0 'Headset' 6dB
amixer set -D hw:0 'HeadsetL Mixer AudioL2' on
amixer set -D hw:0 'HeadsetR Mixer AudioR2' on

SGX Video Acceleration

You can test the SGX with a DEMO, grab and untar the SDK Demo Package

wget http://neuvoo.org/neuvoo/distfiles/SGX-3.01.00.07-SDK.tar.gz
tar xzf SGX-3.01.00.07-SDK.tar.gz

Then to run the demos just get into the X11 Binaries directory (e.g. OGLES/SDKPackage/Binaries/CommonX11/Demos/EvilSkull) and run the demo:

./OGLESEvilSkull

DSP using dspbridge

DVI output:

fw_setenv bootargs-base 'console=ttyS2,115200n8 console=tty0 omapdss.def_disp=dvi omapfb.mode=dvi:1024x768MR-32@60'

Edit the InputDevice section in your xorg.conf

cat >> /etc/X11/xorg.conf << EOF
Section "InputDevice"
       Identifier      "Configured Touchscreen"
       Driver          "tslib"
       Option          "CorePointer"           "true"
       Option          "SendCoreEvents"        "true"
       Option          "Device"                "/dev/input/touchscreen0"
       Option          "Protocol"              "Auto"
EndSection
EOF

Add "Configured Touchscreen" in "ServerLayout" section and remove "Configured Mouse"

Section "ServerLayout"
   Identifier    "Default Layout"
   Screen        "Default Screen"
   InputDevice    "Generic Keyboard"
#   InputDevice    "Configured Mouse"
   InputDevice    "Configured Touchscreen"
   Option         "AllowEmptyInput" "no"
EndSection

Edit /etc/formfactor/machconfig like this

HAVE_TOUCHSCREEN=1
HAVE_KEYBOARD=0

calibrate your touchscreen

for Powertip 4.3 inch (480 x RGB x 272) TFT:

echo -n "8407 -476 -31410144 3 -4861 38051952 655366" > /etc/pointercal

for Seiko 7.0 inch WVGA (800 x RGB x 480) TFT:

echo -n "13714 0 -56041568 1 -8076 63332096 6553665536" > /etc/pointercal

or 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

CAN

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

/sbin/ip link set can0 up type can bitrate 125000

On the receiver side:

candump can0

On the sender side:

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 do again
