2003 BMW M3 Custom Dash / Overhead Console - Page 9

Yes. I have started on an interface written using SDL/OpenGL/SDL_perl. The design is pretty simplistic and easy and despite people who are detractors of "scripting" interfaces, it gets over 1000fps on my desktop when unthrottled. It doesn't have any kind of dial widgets now, but I guess that could be written.

I probably won't have time to get back to it for another month or two though, and it's not even really in a workable state right now anyway. I just got a pinball machine too so restoring it is kind of my current 'in progress' project. I will be posting more here when I make more progress on it. It will be opensource. The target platform is Linux but due to SDL and perl, it should be fairly straightforward to get it running on Win32 or OS/X also.

5s to kernel load is achieved with LinuxBIOS. There's a lot of work still to be done with the EPIA-M board, and until that is done there are problems with RAM and ACPI, so it's not really production ready yet, but it will be within a few months...

indianfury: I am not using Xcar, nor have I tried it... I had a little I-Bus wheelkey app that I wrote that despite its limited functionality allows me to change the volume (and that is it).. I would be happy to send the source code, but I dont even think it compiles anymore...

Hi,

Nice setup by the way. I too have an E46 M3 SMG2 in the Uk and am currently doing something similar. Did you ever manager to write that software you were talking about, i.e. that mapped the 9600E81 Ibus to specific keys, with a small ini file you could make those buttons do anything. That would just be cool. Also out of interest how do you hibernate the PC etc, as I say I am new to this!

I have an e36 m3, but I feel obligated to chome in here

. To hibernate my pc, I wired a switch to the front dash and push it to turn on the puter and to hibernate. You can set what the power button does in the power tab under screen properties.

I just installed a CarPC in my 2003 E46 M3 and will be posting pictures tonight....any recommendations on keeping the PC cool? I have a mini pc but it seems to get a little warm. Any recommendations from anyone? Also what does everyone use for a GPS application? I've tried map point from Microsoft and a few others but they aren't too user friendly. My setup has the following:

Touchscreen 7"
GPS - Navman
Gyration Keyboard & Mouse
Aux Input for direct sound into the stereo
3 Ghz machine with 512MB DDR Ram
80GB Hard Drive
DVD+R/RW-R/RW Drive
802.11B Wireless Connectivity(only works near hotspots)

JustWaiting: Very nice! I wish I had seen more of these e46 mounts with the screen down where you put it before I started my project; I might have done that instead. It would certainly be les glare! Your trunk looks about like mine when I first started.. now I've got it all cleaned up and beautified.

New trunk here: http://www.blurbco.com/~gork/carpc/phase2/DCP_0706.JPG

I have the functionality now....next is cleanup phase and optimizing it. I need a good simple GPS program. I tried road and streets, mappoint 2004 but they are not simple to use. Any recommendations?

I have copilot, and I think it's the best software to use as a driver with a touchscreen. Still, the interface pales in comparison to using something like a Garmin Streetpilot which work infinitely better. I would like to write an emulator for the Garmin GPS's for use on a carpc, and I'm looking for someone with a Garmin Streetpilot 2610/20/50 that can assist me with a couple things.

Anyway on copilot -- the buttons are too big, the text on the map is too small. Except when it is in "Driver" mode, the interface is basically designed for a larger screen laptop running at 1024x768 sitting in a normal computing position. There is still no good way to make adjustments to it that would make it better. Some folks have hacked on it with various resource editors to make the buttons smaller with limited success.

Garmin has some software out too that may be a bit better, but this has yet to be seen.

I have the IBUS interface but I haven't linked up anything to it yet....what have you used the ibus for? I would like the computer to know different ibus notifications...I may try copilot...what version of copilot are you running?

gork · 06-25-2004, 11:19 AM

I run copilot 2003 due to the screen size issues, but the maps are farily dated.

I use the I-Bus for volume control and app switching. The only software I have for it is some stuff I custom wrote into my in-progress application. You will not be able to do much with the I-Bus since you kept the radio. If you don't have the BMW phone (seriously, who does) you can trap events from the two phone buttons on the steering wheel. You may also be able to send commands from the pc to the radio to tell it to switch modes, etc. There might be a way to output some text to the radio screen also. Look to the HackTheIbus group on yahoo groups for more.

As a side note, I get more emails and PM's from people about the I-Bus than anything else. I think I have said this before, but please do not contact me (sometimes repeatedly) about I-Bus stuff. I do not have any software that works under windows to do anything with the I-Bus. I abandoned my efforts under windows a long time ago. I also, do not know very much about the I-Bus aside from using it to 'listen' for events. In all likelyhood, using the I-Bus will mean that you are going to be writing your own software to communicate with it. /End PSA

where is the 3-pin i-bus interface located on the m3?

gork · 06-25-2004, 12:08 PM

It's in the trunk on the left wrapped up in a bundle. You can access the I-Bus on the three wire connector for the telephone or in the CD changer harness. The best way to find it is to turn the car on (start the engine, turn the radio on) and use an oscilloscope between GND and your probe to find the IBus wire. The I-Bus is normally 12V (so it looks like a battery wire), and goes to 0V when transmitting a bit, so you can see these on a scope. In the 3-wire harness you have 12V Batt, GND, and Ibus. Don't get them mixed up or you will blow the telephone fuse!

thanks, gork!

saves the trouble of running a serial cable across the car.
