Welcome to OpenBM project webpage
Hi, my name is Art Tevs and I would like to present you the project named OpenBM_E39.
OpenBM stands for: Open Source Bordmonitor. The project is mainly targeting all BMW enthusiasts, who would like to improve the standard BMW multimedia equipment with their own configurations. On this webpage, I would like to present you a device made out of the original BMW's 16:9 bordmonitor housing found mainly in E39/E38 as also X5. The device can seamlessly be included into original BMW equipment and deals as an output/input device for a CarPC.
You can find all available code at Github repository: OpenBM-Repository
- Original Look 16:9 Bordmonitor with a CarPC.
- use Bordmonitor for Input/Output? of CarPC
- Being able to seamlessly connect Rearview camera as also DVB-T/DVD
- Be cheap
Here is a list of current features supported by the device.
- 800x480 native pixel resolution
- 3 Input sources, 1xVGA and 2xAV (composite video)
- Full support of all buttons and encoders. Buttons support press, hold and release states
- All the control LEDs can be set into any flashing state controlled by a bit pattern, i.e. 11111111 - LED on, 01010101 LED flash every 1/8sek
- Support switching between video sources as also turning on and off of the display
- Automatic switch to AV1/AV2 when 'R' gear is selected (reverse camera)
- Original Photo-Sensor of the bordmonitor is used to change the brightness of the display
- Complete emulation of MID device through OpenBM.
- Supports following configurations:
- BMW Professional RDS
- BMW Buisiness with DSP
- XBMC is running as a front-end software
- Plugin to control the on-board computer
The software used by the OpenBM device is currently not publicly available. However, you can ask me for it. I will put online several parts of it, if somebody is get interested.
I developed a Linux daemon, which interacts between serial port (this is where BMW's i-bus will be connected later to a CarPC) and local TCP/IP stack.
I have summarized information about used CarPC on the Hardware page. As base for the CarPC I am using ZOTAC's IonITX series F board (with WLAN) housing in an VoomPC-2 enclosure.
Main software is based on XMBC for which I wrote several plugins. The information for the software can be found on Main Software page.
I wrote a documentation for OpenBM as a final device. The documentation is in german, since this is the small market I am currently targeting :) download here
The following list represents the timeline of this project. Every time there is new event, it will be published on an extra wiki-page and added to the list. So take a look on those events, already happened :)
| May 2013 || I've put the schematics and pictures of the newest HW revision online. Additionally a part-list is included, hence anybody who would like to build the same thing are welcome to use this project as a starting point.
| July, 2011 || Using 16:9 6.5 screen now
| 07th, September 2010 || I've added couple of screenshots showing the self-made plugins to control BMW's equipment in action :)
| 31th, August 2010 || Added information about new release of a gateway between IBus and software applications. D-Bus support is dropped.. TCP/IP is added :)
| 30th, August 2010 || I've updated the session about the CarPC showing images with installation. Also a frame for the radio was rebuilt, here you can find more impressions.
| 9th, August 2010 || For my CarPC I am using the XBMC multimedia software. I am currently working on a plugin for this piece of software to control the core BMW equipment.
| 20th, July 2010 || First release of IBus/D-Bus Gateway. A daemon running in the background and forwarding messages between IBus (hardware) and D-Bus (software).
| 26th, June 2010 || Based on the original 4:3 frame the OpenBM housing was created. Additionally cables required for CarPC were installed.
| 3th, June 2010 || OpenBM is just a video output device. In order to bring audio into my car, I installed an AUX-In in the BMW Professional RDS radio.
| 1st, June 2010 || First software running emulating MID device. I made a video showing the device in action.
| April 2010 || Prototype replaced by professionally etched PCB. SMD soldering and error patching was then performed by hand.
| January 2010 || First prototype of a button field controller module for the bordmonitor housing
| October 2009 || Put a new display into the bordmonitor housing. In this case I am using a 7'' display with native resolution of 800x480 pixels.
| October 2009 || Reverse engineering of original BMW's 16:9 bordmonitor housing. Special interest goes to the both button fields as also LEDs
At this place, I would like to thank Bengt-Olof-Swing for his helpfull comments. You can visit a thread from MP3car-forum where he shows his results on an equivalent project so far, click here.
