Car PC project(August 2013 update)

This is an update for my CarPC project.
You can download the latest image from the link on the top right corner of this blog(username:'pi', password:'a').
The main features are:
Hardware:
Software:
[Operating System]
    - Raspbian Wheezy 9.February.2013
    - Custom kernel 3.6.11
        - eGalax touch screen module
        - si470x usb radio module
        - snd-usb-audio module

[Media Center]
    - omxplayer
    - XBMC 12.2 Frodo
        - media formats supported:  listed here
        - sources with objects build on 27.July.2013
        - skin: CarPC-touch(download current version)
            - system shutdown button(safely stop xbmc and safely halt)
            - reload skin button
            - switch to camera view button
        - modified spectrum analyzer(OpenGL with no rotation)
        - eGalax touch screen calibrated
        - eGalax touch screen click&drag fix
        - black rectangle behind XBMC removed
        - patch to add getMousePosition feature to xbmcgui module(used to redirect clicks from the Navigation skin page to X11 using xdotool)

[Navigation]
    - Navit build from source
    - Zoom In, Zoom Out buttons
    - Click sent from XBMC to X11 (Navit Window)

GPS Setup
1. Connect GPS module to UART TX, UART RX, GND and 3.3V or on a usb port.
2. If you are using an UART GPS module, as I did, use this tutorial or any other to setup UART communication.
3. Connect GPS to gpsd:
sudo apt-get install gpsd
gpsd /dev/ttyAMA0

Adding maps to Navit
In order to add new maps to Navit, there is a simple process. First, go to Navit Planet Extractor and download your desired area file(this will be a .bin file).
After this, transfer the file to your Raspberry PI in the folder /home/pi/navit_export/build/navit/maps/. Here, you should also update the existing .xml file and add another entry for your new map. My .xml file is looking like this:
<map type="binfile" data="$NAVIT_SHAREDIR/maps/osm_bbox_11.3,47.9,11.7,48.2.bin" />
<map type="binfile" data="$NAVIT_SHAREDIR/maps/osm_bbox_20.3,43.5,29.9,48.4.bin" />
You can rename your .bin files for easier management

Car Modding
I had to relocate my original Radio/CD player in the trunk and keep it set on aux input source. This included buying about 60m of wires and also harness:
1. Metra 71-9003 Bmw Mini Factory Radio OEM Wire Harness
2. Scosche VW03B 2002+ Vw Audi BMW Radio Stereo Harness

 front without OEM Radio/CD player
trunk with relocated OEM Radio/CD player
Mounted Raspberry PI in the armrest
Safety:
    - The wires are 2mm in diameter with good insulation, resistant at temperature variations
    - I have added fuses(1.5A for the radio, 1A for Raspberry PI, 1A for display, 0.1A for reverse camera trigger, 0.1A for reverse camera video signal)

Bugs:
     - sound pops(will soon disappear by using this hdmi to hdmi and audio splitter)
    - Navigation is behind Video Player -> Navigation isn't visible while playing videos(this isn't a big issue)

  3. Hey there,

    I'm trying to get my eGalax TS working under XBMC since, I dont know when. I really tried a lot. But your approach seems to be the most promissing. But when I tried to install the two patches you provided, i couldn't find the files to patch. So is there any special version of XBMC I have to install?

    Thanks for an answer

  4. Buna ziua Andrei!
    First of all, I want to thank you for your awesome job. I'm making a project in my university and your work was really helpful for me.
    I wanted to ask you, how could you manage to connect the raspi and the screen to the power of the car? In my project, I want to connect both of them to a rechargeable battery, but I don't really know how to do it. Could you please give me some instructions?
    Multumesc mult!

    1. Hola Shuco!

      I am glad that my work helped you.
      Well, regarding wiring the screen and the PI to the car I have did the following:
      Find constant 12V+ and 12V- behind my Car stereo and split the wire in 2xthree wires(actually used some harness wires from eBay: http://www.ebay.com/itm/Metra-71-9003-Bmw-Mini-Factory-Radio-OEM-Wire-Harness-/330529294873?pt=Car_Audio_Video&hash=item4cf514ca19).
      So, I have the following diagram:
      +--->12V to 5V adaptor with micro usb(cheap car charger)--> Raspberry PI
      |
      +--->OEM Car Radio(original wires)
      |
      +--->Display 12V DC in
      OEM Car Radio is used as sound amplifier(3.5mm jack to 3.5mm jack wire is used)
      Be careful with the current needed. My system needs:
      - 700mA for the Raspberry PI(but you can add 500mA maximum for each usb device plugged in -> mine works fine with 1A fuse for Raspberry PI USB touch screen and one USB Pen Drive)
      - 1.5A maximum for my Radio(at maximum volume)
      - 600mA for the display

      Regards,
      Andrei

  6. Andrei, thank you for the reply. But, it did not work.
    Here is my problem. For example. The Home button is in the top left corner. But, I have to
    touch the top right corner for it to work. The Videos/Music/Pictures, etc. is on the left side. But, I have to touch the right side of the screen for it to work. It seems everything is mirrored.
    Thank you!
    BTW. I found this for my startup and shutdown http://mausberrycircuits.com/car-power-supply-ignition-switch/

    1. Hi!

      Well, it seems that only your x axis is inverted. So. in order to switch this axis, we have to take a llok at the formula implemented in XBMC code, by my patch:
      pointer.x = screen_width - value_read.x * calib_x_fact - calib_x_d;
      In order to change axis orientation you have to do some changes to the /usr/share/eGalaxCalibration/touchscreen_axes_calib file:
      1. set calib_x_fact as a negative value
      2. set calib_x_d equal to screen width(in my case 1280)
      You can apply math to see what it does to the equation. You can read more about this on one of my previous posts: http://www.engineering-diy.blogspot.ro/2013/02/raspberry-pi-raspbian-xbmc-and-egalax-7.html on paragraphs 4 and 5.
      BTW: The car ignition switch is a very good solution, but in my car I have a general on/off switch to be sure that no current is drawn while I am away.

    2. I got it to work! Thank you very much. I suck at math and coding. But am good at hardware hacking. So, not sure how I calculated it. But, it works.

      Now. where did you put your map file? I looked in Navit-Maps but did not see it. I want to replace it with my own .bin

      Delete
    3. Great!

      I have put my .bin file in the folder /home/pi/navit_export/build/navit/maps/
      Also I have updated the .xml file from the same location and added a new entry with path to the new map.

    1. Hi!

      1) For the X axis you have this formula implementer in XBMC:
      pointer.x = screen_width - value_read.x * calib_x_fact - calib_x_d;
      To revert x axis orientation you have to set calib_x_fact as a negative value and calib_y_d equal to your screen width in pixels. The equation will become:
      pointer.x = screen_width - value_read.x * (-calib_x_fact) - screen_width;
      Which will be
      pointer.x = value_read.x * calib_x_fact;
      If you want to move the click frame left or right(if your pointer is left or right from your click point) you have to tweak calib_y_d(increase or decrease it).

      Delete
    2. Regarding the second issue I don't know how to help you. Maybe you have to tweak overscan values in the file /boot/config.txt. See http://elinux.org/RPiconfig

  14. Hello Andrei,

    first of all: great job!

    I'm following your blog since i started my raspberry-experience a few months ago. I liked your blog, because it's very rare to find someone who is able to do the work on his own and THEN is still able to do the documentation! I really appreciate what you are doing!

    but: i can't download your latest image! google tells me that there are wrong permissions on the file?
    I hope you can fix that, because i hope that you have done the work i wasn't able to! (i destroyed my brain while testing with the xbmc and egalax-touchscreen! :D)

    Great job, and go on!

  15. Hello Andrei,

    the download is working now, props for that! ;-)

    I have several SD-Cards with multiple builds and distributions, it just bothers me at the moment.
    I either have a running OS with supported and working Touchscreen but couldn't get XBMC up and running, or i had a working XBMC (like OpenELEC/Raspbmc) with no touch-Support... :-(

    I hope i can restart my project now. At least we BMW-drivers have to stick together, right? ;-)

    Do you have any plans for the CarPC to connect to your Home-WLAN and get synced with some kind of NAS? I'm an iTunes-Fanboy and have all my music and stuff on my NAS. So I want to have an automatic sync between my Car and my other devices.

    And one last question: Does your image support the Airplay-function? I Would LOVE to connect my iPhone to my car and quick buy and play music / videos from there! :D

    I hope the project is getting more viral, because it seems to be a very solib build! :-)

    1. Hi Knut!

      I have used Edimax wifi dongle and created a hotspot with my Android phone. With this I have internet on the CarPC and also support for XBMC remotes. Official XBMC remote has some nice feature which display a nice popup for every call or SMS received on the phone.
      The build also contains airplay support but I haven't tested and don't know if it is working.
      At this moment I am trying to integrate my changes in OpenELEC(it boots in less than 30 seconds).

    2. Hello Andrei,

      I am using a TP-Link Wifi Dongle. The one I use had some troubles on the raspberry (There were some version-troubles with the driver :-( ). I hope that i can use it with your image. I have downloaded it, but couldn't test ist yet. At least i can install the driver on my own, i already did this a few times on raspbian.

      Thank you for the info about the XBMC remote. I'll try it out!

      When I've tested the Airplay, i will give you Feedback about it. With the raspbmc i had some troubles using it. Bad connection or no video, just sound...

      Why do you now choose openELEC instead of raspbmc? Are there minor or major differences?

      Knut

    3. Hi Knut,

      I suggest you to use EDIMAX EW-7811UN. It is about 10 euros and it is working out of the box with no issue.

  16. Hello Andrei
    I'm wanting to make subtle changes to your skin.
    The volume slider for me is too close to the bottom of the screen and is fiddly to get the right volume.
    Where are the xml files stored that control the sizes and positions? I'm assuming that I don't have to build xbmc again to change this? Have you deleted the xbmc build directories from your image? If not could you tell me where they are.
    Thanks

    1. Hi!

      You don't have to build xbmc for this.
      You just have to edit the skin. The skin is located in the folder /home/pi/.xbmc/addons/skin.CarPC or something similar.
      Here, in the folder 16x9 you will find all the xml files needed.
      The volume controls are defined in the file includes.xml(search for "CommonVolumeBottom").
      This is include whenever is needed. For example, in the file Home.xml(which is the main screen).
      Please let me know about your setup :-)

      Good luck!

    2. I'm looking at using th TDA7416 Car radio processor chip to do all my mixing. The chip is i2c controlled. I would need to add a screen that has all the input selection fading and equalization.
      I'm not sure what I'm writing it in yet. I haven't looked at it yet but am I able to redirect the volume control slider to control my master volume instead of the PI's sound card - without recompilation?

      Delete
    3. Hi!

      The easiest way to do this is to create two python scripts(one for volume up and another for volume down) and create two buttons in the XBMC skin which will call these scripts.
      Regarding the slider, I don't think you can do the same. Please look at:
      http://wiki.xbmc.org/?title=Slider_Control
      For the action tag only volume(for XBMC) and seek are avsilable.

    1. Hi!

      Well, my system automatically boots into LXDE(you can enable this using raspi-config).
      After LXDE starts, it executes the script /etc/xdg/lxsession/LXDE/autostart.
      I have added at the end of the file this:
      cd /home/pi
      ./navigation_startup
      In /home/pi I have created a file named navigation_startup and put the following text inside:
      # Start Navit and gpsd
      sudo killall -9 gpsd
      gpsd /dev/ttyAMA0
      cd /home/pi/navit_export/build/navit/

    4. Hi!

      In my build(for RPi) xbmc shows only what does the skin wants. If you remove all the items from on page, for example, you will only see what's behind xbmc.
      I have found this the hard way, by looking days through the code and searching where the transparency can be changed.
      In the latest firmware for RPI this is not working any more, so I have to use the firmware from February 2013.
      I don't know what to say regarding other systems than Raspberry PI, I am sorry.

      Good luck!

    5. Hi!

      You can set transparent areas in the XBMC skin. Please have a look at the xml files from /home/pi/.xbmc/addons/skin.CarPC-touch/16x9/
      For example, Home.xml is the xml file which sets the Home page(first that appears after starting XBMC).

      ST22 pins are like this: http://www.google.ro/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CDQQFjAA&url=http%3A%2F%2Fwww.perthold.de%2FBINARY%2Fgps-st22.pdf&ei=MpBlUvK8KoPt4gT1joGwCA&usg=AFQjCNFiMiS1df11g5-sDKxdrH2b8mQyIg&sig2=gM7LPcS82fXiGrsMRIxM1g&bvm=bv.54934254,d.bGE&cad=rja
      See page 5.
      The connections should be made like this:
      GPS ST22 RPI
      GND 3 black
      VIN 4 3.3V red
      UART RX 1 UART TX green 15
      UART TX 2 UART RX green 16

      2. Regarding Openstreetmaps you can download updated maps from here http://download.geofabrik.de/europe.html. The Navit planet extractor seems to have a bug.

    3. Hi Andrei,

      I'm trying to install the image but it's not working. I'm having the same problem as Steven McCullough. When i start my RPI the green light blinks one time and the red one stays on.

      I also tried the new image you mentioned, didn't work. Can you help me out with this?

      btw: i've got my map (wohoo!)

    4. Hi Richard!

      I am sorry but at this moment my builds are based on the February RPI firmware which seems to be too old for the new versions of RPI.
      I will try to do something about this, but at this moment I am trying to finish the FM radio setup(which works great :D).
      I will try to find a solution for this as soon as I finish with the radio.

  32. Hi. Have you thought about using the audio lines feeding to the AMP to output directly to the AMP instead of going through the radio? You would only need to use the remote amp connection to power up the amp.
    I'm thinking about trying this in my BMW (E90 2008) and also considering to try to use as video output the CCC large screen.

    2. Managed to log in :) So why not buy an amp? I found the aux in to have sub-par quality to be honest. I'm also from Bucharest :) maybe we can meet sometime and share some ideas. Still waiting to get a chip and cable to connect to my obd, until then i dont wanna start anything.
      I wanna try and route as much from my car controls to the raspberry, maybe even the iDrive knob wheel :) and i've recently started investigating a HUD solution.

    3. Hi Chris!

      I haven't bought an amp because I was advised that it is almost impossible to find an amp which will work perfectly for my original car's speakers. I have the basic system, so the high filtering is done from the OEM amplifier. I have done some work in adding external controls for XBMC(based on GPIO's) and I have connected so far buttons and rotary encoders, and are working very well. I will love to find one iDrive knob, because my car doesn't have one, but I haven't found yet.

  36. I like the video review and had a few questions for you about this setup. Does the image you supplied at the top already have the xbmc setup with the touch skin already in it? Another thing related to the supplied image, is it setup for a reverse camera so it just needs to be plugged in? Also, the ST22 GPS module you linked to, I'm under the impression that needs to have a clear view at a window correct? Those are the three major things I'm worried about, the rest is mainly due to the steering wheel controls and bluetooth for my phone that my car already has. I figure I'll just hook the rasbpbrry pi up to the aux input and when I get an incoming call I can just hit the answer button my my steering wheel. At some point I do want to add displays for the rear seats and I'm thinking usb displays, which since it's linux based so I can work it pretty well having time with ubuntu, question is do you think a usb powered hub would work? Thanks in advance, I'm looking to make this my winter project so I want to thank you for all your information you've provided online!

    1. Hi!
      To answer your questions:
      - The image in this page have everything set up as in the video.
      - The reverse camera is directlly plugged into the screen controller via S-Video(there is no link with RPI, the display controller does the switch to S-Video when you put into Reverse - check out the page for the display in the eBay link)
      - I have put my gps right on top of the dash so it has directly window link and I don't know how it will behave when under the dash
      - Regarding the last issue, a usb powered hub will surely work, but you will be needing a powerful machine to handle this.

      Delete
    2. I appreciate it greatly! That is great to know, I was tempted to poke around the image just to see what's in it and maybe personalize it for maps etc. I'll probably be using raspberry pi model B with 512 Ram so if I do use rear displays they will be 100% mirrors no stretching or individual screens.

      The gps, I'm guessing those need to have wires soldered on? NO big deal just curious as to what type of line/adapter you used to help make my life more simple.

      I've been pondering the startup/shutdown procedure as I don't want to sit in the car and have to manually shut it down before getting out. I've been looking at startup/shutdown controllers so I can have it wired to a always on circuit and the controller to the ignition system so it goes up when on and sends the shutdown when off. I found on here:

      http://www.mo-co-so.com/MPEGbox-uSDC-p/mcs-atx-usdc.htm

      Not sure how much of a pain it'll be to wire it up to a pi but it's as close as I've been able to find as a solution unless you have an idea.

      Thanks again, this is a wealth of information that has been very useful.

    3. Hi Barrett!

      To hook up the gps receiver you have to do some soldering to add some pins. If you buy an usb you won't be needing any soldering, just plug and play. I don't know what do you mean by "line/adapter".
      For the power, the best choice will be to put an automatically switch. in my car, I have a on/off switch to be sure that everything(RPI, GPS and display) is off. If I leave this button in the on position, after one hour or so, my car switches off the power and when I unlock the car it restores power so RPI starts automatically.

      Delete
  37. Or is it stable enough to just let it power off with the car, would save time and effort.

    ReplyDelete
    Replies
    1. The best thing is to invoke the command sudo halt somehow and then wait for the complete shut down and after this cut off the power. I know that some guys are working at this kind of devices, just search for automatic switch.

  38. Hello,

    Firstly, thank you for sharing your awesome work. Found you as soon as I googled 'Raspberry Pi Car PC'.

    My current hardware:
    -Raspberry Pi Model B (OpenELEC XBMC)
    -8GB Class 10 SD
    -7inch HD Touchscreen with USB

    I had a couple of question before starting the CarPC project...

    1) Will OpenELEC XBMC work as a CarPC OS?
    2) For the headunit to be relocated to the boot, did you get another harness and just link it to the exisiting harness behind the dash? Or was it a little more complex?
    3) How do you control your radio?

    Thanks again,
    Shane

    1. Hi!

      1) OpenElec does not have an X11 interface, so you cannot run Navit. It is very difficult to add new programs to OpenElec(such as gpsd or navit or the entire X11 window manager). I have tried to add gpsd without success. The trickiest part is that you have to add programs at build time.
      2) To relocate the head unit in the trunk I have used two harness sets, one for the original plug in the dash and another one for the radio plug and very long cables(~4m) between them.
      3) I do not control the radio at all. It is always set to aux and some high volume level. I control the volume from the PI. If you are referring to the AM/FM radio, I am waiting for a radio module from eBay to hook it up to RPI and control it completely from XBMC

  39. Hi Andrei,
    First of all, your project is awesome, I like it very much.
    I'm thinking in a similar project but I don't know if it is possible, so I wait you can help me. The idea is to connect rpi to my car system. The car system has a LCD 7" (GCX156AKM-E). There are two options:
    1) Use a video interfaz for my car, in which case the rpi going to connect to interfaz via RCA. The question is, Can I use a board like this --- to manage touch screen?

    2) I don't know if there is a control board like you use for your project to control the car's LCD.

    What do you think about it?

    2. Hi Carlos!

      1) You can use the S-Video output from the Raspberry PI, but the video quality won't be as good as with hdmi.
      2) The usb controller is just for the touch(which is a thin transparent film on top of the screen, if you do have one). This film should have 4 wires which can be connected to the USB controller pointed by you.

    3. I think my explanation is not very clear, I mean the follow:
      1)The big problem to use a S-Video output from rpi is can be able to manage the system through car's LCD, then I'm asking if is possible make this with a USB controller.

      2)Regarding a control board, I mean this one http://www.ebay.es/itm/7inch-AT070TN92-LCD-HDMI-VGA-2AV-driver-board-Touch-Panel-For-Raspberry-Pi-/151074149637?pt=Bauteile&hash=item232cb89505, and my question is if there is a similar board to support my LCD.

Or is it a slow boot the first time round?

    1. Hi Sven!

      1) I haven't tried anything with OBD yet, but I am planing to do this after finishing with the FM radio SI4703.
      2) The remote app use sockets to send commands to XBMC, so, you have to run XBMC on a machine(with an ip address) and rpi-remote on another machine(with another ip address). Then, you just have to set the correct IP address in the config file. You can also compile the remote app for another architecture(make & sudo make install). You just have to disable the code for GPIO's, which works just on RPI.

      It seems that your card is not supported in my custom build kernel. I suggest you to start your PI with the default Raspbian image(which works for your wifi card) and then send me the result of "zcat /proc/config.gz". It should create a .config file which contains the kernel settings. I will use this to update my kernel for the future release.

  43. So I'm starting from scratch as I'm using different hardware and everything is working except I can't mimic how you have navit embedded in xbmc. Can you tell me how that's done or point me to the xbmc files that need to be edited?

    1. Hi Barrett!

      Controlling Navit from XBMC was the trickiest part.
      While running the first Raspberry PI XBMC builds I saw that the default screensaver fades the screen and you can see what is behind XBMC(like X11 windows).
      My idea was to automatically boot in LXDE and then automatically start Navit and after this, start Xbmc. I have searched through the XBMC code and first I have created a patch for XBMC to add a new python method for sendind clik events to x11(via xdotool program). The patch is at http://code.google.com/p/andrei-development/downloads/detail?name=xbmcgui_getMousePosition.diff. This patch is available in the August image. After playing a while with this I have discovered that the response is kind of slow(from the moment you touch he screen until it does the click in the Navit window).
      So, to improve this I have added code to send clicks directly in the click process function(without any Python between). The file is:
      xbmc/input/MouseStat.cpp in function void CMouseStat::HandleEvent(XBMC_Event& newEvent)
      Include a new header:
      #include "guilib/GUIWindowManager.h"
      After this code:
      else if (newEvent.button.type == XBMC_MOUSEBUTTONUP)
      {
      if (newEvent.button.button == XBMC_BUTTON_LEFT)
      {
      I have added this code:
      m_mouseState.button[MOUSE_LEFT_BUTTON] = false;
      if(g_windowManager.GetActiveWindow() == 11114)
      {
      char command[60];
      memset(command, 0, 60);
      sprintf(command, "xdotool mousemove %i %i click 1",
      newEvent.motion.x,
      newEvent.motion.y);
      system((const char*)command);
      }
      If you don't know how xdotool works you can find documentation on the web.
      This code sends clicks to X11 windows only from the XBMC skin page which has window id 1114(I dont know why there should be a '1' less).
      The Navigation skin xml page should start with this:

      After this I have removed the background in this skin page and put only one button in the bottom right to allow going back.

      If I can help you more please contact me on G+

      It is not good at all in direct sunlight. You can find one good for direct sunlight on eBay but it is little more expensive. You can also add some tint to your rear windows of your car and you won't have issues with the sun.

  48. Hi Andrei,

    I'm trying to compile the si470x usb radio module on a fresh install of Raspbian, but I'm having some issues.

    When compiling gcc gives me this error:
    fatal error: linux/usb.h: No such file or directory

    I have tried installing libusb-dev but still no sucess! Could you tell me how you managed to compile this module?

    Thanks a lot,
    Alex.

    1. Hi!

      I have added the module in the kernel directly and it compiled.
      If you want to build it by yourself you have to check the include paths in the makefile(the ones starting with -I) and make sure that usb.h is in one of those folders.

  49. I am having trouble booting CarPC_aug_12_2013.img. I have flashed the image 4 times using DD and a freshly formatted SD card to no avail. The activity light flashes for a split second and then just the power light stays on. I have the RPI model B with 512mb RAM. Perhaps this is the issue? Any advice would be appreciated. Thanks and great job!

    1. Hi!

      I am having Raspberry PI model B rev 2. I have seen this kind of issues with cards that has stopped working with my card reader also.
      Also, there are some new Raspberry pi boards which seems that are not supported by the February firmware, which I am using.

  50. Hello Andrei,

    we are still trying to use your image. We have a Touchscreen from Faytech and the Raspberry Pi with 512MB. We bring the Image on the SD Card an than we will start it. It starts but the X and the Y Axis are mirrored. In XBMC and outside XBMC. We tried to change the swap_axis to 1 and we changed the X and Y calib_.._fact with * -1.

    We don't know how to fix it. Can you pleas help us?

    We paste it first in the wrong thread, sorry ;)

    1. Hi!

      You can use sudo in every command you like(in a skin or in a python script).
      You can add a button in the home screen like this:
      Edit the file /home/pi/.xbmc/addons/skin.CarPC-touch/16x9/Home.xml and add the following item at the end of the file where are other items:

      RunScript("special://skin/scripts/xbmc_quit.py")
      icon_logoff.png

      After this, add/edit the file:
      /home/pi/.xbmc/addons/skin.CarPC-touch/scripts/xbmc_quit.py
      And put hte folowing code:
      import os
      import xbmc

      xbmc.executebuiltin('XBMC.Quit');
      os.system("sudo killall -9 xbmc.bin");
      Now, reload the skin and test.

    2. Hi!

      The file touchscreen_axes_calib should be put in /storage for the OpenElecRPIeGalax.tar.gz image. For other images it should be put in /usr/local/share/eGalaxCalibration/
      If you have a working touchscreen_axes_calib file for your display it should work for all the releases.
      Justin, for getting into command line you can always use ssh.
      For calibrating the X11 using xinput-calibrator you have to kill xbmc from ssh and after this connect using a keyboard and callxinput-calibrator. Also, if you have a calibration file from an old build(/usr/share/X11/xorg.conf.d/01-input.conf) you can use it, without being necessary to recalibrate.
      If you have more issues, please contact me directly via Gtalk, Skype or YM.

      At this moment I am working on a better touch support for Navit and also I am adding an FM radio and some universal hardware buttons support.

    My edimax WiFi USB is non working.
    And also my x axis touch is inverted..I can live with the WiFi not working for now but I am eager to get the touch screen working perfect.
    I am willing to try and calibrate it but the settings or commands you provide in previous post have me lost. I don't know where to implement them as I have no experience in using them. Can you please help me fix my calibration or point me to where I can know how to input your calibration settings? Thank you!!!

  70. Well I want to dive into xbmc skin to see whats going on with it, I know linux decently and xbmc pretty well but as far as the skin I don't even know where to look as far as how you made a certain area transparent to show the x11 app behind it.

    Is there anyway you could tell me which file in the xbmc retouched skin you edited to show an x11 app? And specifically what it was you changed? My idea is to start from scratch with the latest software and begin going through it, just need a starting place of where your at.

    Thanks :) And I agree about the on off button.. maybe I'll put in an on/off switch between it and leave it in on mode unless there's a problem.

    2. Hi Barrett!

      Please have a look at the file: /home/pi/.xbmc/addons/skin.CarPC-touch/16x9/Home.xml. Here I am setting the buttons for the Main Menu. The Navigation button looks just like this:

      ActivateWindow(1114)
      special://skin/media/navit_logo.png

      This jumps to the window with ID 1114. This window is defined in the file: custom_navit_1114.xml from the same location as above. This page contains just a button for the back action(or several buttons I don't remember well). The trick is that XBMC will render just what you have in your skin. If you have just a button that is all that XBMC will render and in the rest of the screen you will see what is behind(which is Navit runing on LXDE).
      For click to work I had to insert some code in the XBMC code and say that if the window ID is 1114 to redirect all the clicks to X11(using xdotool). This is a bit more complicated, but it works so you don't have to bother with it.

    what raspberry pi would you recommend if I want to have navi, multiple usb that can support the os and external hard drive (250gb +), plays videos (vlc or xbmc), Bluetooth connection with mic support for phone call, and still be able to pick up radio stations? the stock dash on this has a tape player and radio.

    I am hoping to be able to add subs and after market speakers/amps to have a nice sound system if its adaptable with a pi. Please let me know.

      Raspberry PI model B with 512MB will be enough for this job.
      I have this all set up in my car without the phone support(I am planning to add it soon).
      The biggest impediment is that the sound from the PI analog out jack has a lot of pops. For me, the fix was to buy one HDMI to HDMI+audio board (viewHD) and set the PI to output the sound to HDMI. This viewHD box has also the capability to output 5.1 via SPDIF if I remember well.

      Good luck and please let me know of your progress!

    I actualy hoped that you'd have a link to a movie in which you assemble the touchscreen into your car. I've ordered everything but my main concern at the moment is that it'll look horrible in my car, and the touchscreen will not hold the pushing. I somehow need to make a rack that can hold the touchscreen and other hardware in place, and I'll need to finish it with some sort of plastic so it won't look like something I've must have done myself ;-).

  75. My compliments for this excellent piece of work! Like some others, I was unable to boot the PI, obvious because of the newer firmware. I copied the BOOT directory of a recent Raspbian installation, and copied all entries over your files in the BOOT folder, except the older .elf files (didn't try yet what would happen) . It now boots on a recent PI 512MB! The only problem is still the back navigation screen, I still have to read all comments here in detail, but I'm very glad I now have a bootable system.
    Do you have any plans to build a newer version of xvmc? Especially because the newer version is able to play .ISO and TS files with their menu's.

Just haven't had a chance to check but maybe it it doesn't load the black.png image it might show? Or make it a transparent image by having the skin look at a transparent image of the same size with a different name as that might harm other parts of the skin using the same black.png that it refers to for the background.

I'm going to order a newer model to try and find a solution as now I'm curious since it's not in xbmc.

      At this moment you can use push buttons(which I think is the case for steering wheel controls) and also rotary encoders. As actions, you can trigger almost any XBMC action or radio FM action, if you have the fm radio module.

    1. Hi!

      I didn't handle anything from RPI regarding camera. The camera is powered by any power source: licence plate light(will be always on) or reverse bulb(will be on just when the car is in reverse). Now, the display controller, is connected using the svideo output of camera. The display controller has a special pin, which, when connected to 12V, will change the view from whatever it is(hdmi, vga, av1, av2 etc) to AV2 in my case(you can find this info in the ebay link). When that pin will stop receiving 12V the displa controller will switch back to whichever view was before. So, simply connecting this pin to car's + signal of the reverse bulb will do the trick. Remember to put a maximum 100mA fuse to be sure that the current sunk from the car's bulb is always low. So it goes:
      car bulb + connector -------wire------ 120mA fuse ------wire----- ACC pin on display controller
