Hab es momentan ausgebaut rumliegen, will noch den Kodi-Skin verändern und ein HifiBerry-Modul kaufen...
Aber Bilder folgen dann...

Hier mal mein CarPC
Vielleicht bisschen billig im Gegensatz zu anderen...
Ist mit nem Raspberry Pi 3 und Offiziellen Raspberry Touch gemacht -
Also ich habs eben mal getestet.
Hab einfach genau das 7F 05 80 44 29 30 A7 gesendet.
Passiert ist leider nichts.Aber vielleicht hab ich auch irgendwas falsch gemacht...
-
Ich hab das noch nicht getestet, habs gestern abend nur zufällig gefunden.
Schade wärs, wenn man nur Kilometer, KM/H und Temperaturen anzeigen könnte, weils ja kein Text hat, aber muss mal jemand testen (Ich werde es vor dem Wochenende leider nicht testen können) -
Hab mal was interessantes im Netz gefunden:
ZitatSUCCESS!!! (Writing to the BMW E46 display cluster)
I have for some time no wanted to write text to the E46 (low) cluster to advertise speedcameras (speedlimit and distance) using for example "GATSOHunter" and "RoadRunner"
My thought was to have the arrows flashing to draw your attention to the cluster, and then present the current speedlimit followed by the distance to the speedcamera (GATSO).
After some digging through the web I have understood that writing to the E46 (low) cluster is not possible... WRONG!!!
Now I have finally succeeded to do just that...
The clue is that it MIGHT not be possible to DIRECTLY write text to the alphanumeric display, but use it's pre-defined messages kind of...
There are afaik 3 different types of messages that can be displayed:
-Distances in meters or feet
-Speeds in km/h or mph
-Temperature in degrees Celsius or Farenheit
Maby it's possible to write "plain" text as well, this I don't know at the moment.
Today I logged the following _DISTANCE_ codes and tested to write them back to the cluster with success:
_HEX codes WITH checksum attached!_
7F 05 80 44 29 30 A7 <--- 300m
7F 05 80 44 29 25 B2 <--- 250m
...
7F 05 80 44 29 10 87 <--- 100m
7F 05 80 44 21 90 0F <--- 90m
7F 05 80 44 21 80 1F <--- 80m
7F 05 80 44 21 70 EF <--- 70m
7F 05 80 44 21 60 FF <--- 60m
7F 05 80 44 21 50 CF <--- 50m
...
7F 05 80 44 21 10 8F <--- 10m
7F 05 80 44 21 00 9F <--- 0m
7F 05 80 44 20 00 9E <--- CLEAR DISPLAY? (this was the last code logged from the GPS -> IKE
Here the GPS (7F) is the source and the IKE (80) is destination.
The first DATA byte, (the fourth byte in the string) seem to be the code for "distance display". That is the "m" is displayed after the data in the display.
The second DATA byte, (the fifth byte in the string) it is used to distinguish between 100's and 10's.
The third DATA byte, (the sixth byte in the string) is the actual distance data.
I have logged codes for speedlimits as well, but I have lost that log. I'm pretty sure that the format is very similar, but with another hexcode for the FIRST databyte to put the display in "speedmode" for example.
Will test "speeddata" tomorrow...
Kind regards

(REMEMBER, THESE CODES ARE FOR AN E46. THE CODES ARE TRIED ON MY 330d ONLY! EVERY OTHER CAR MIGHT DIE OR GET SOME KIND OF NASTY DISEASE IF THESE CODES ARE TRIED!!!)
Following example codes should be pretty easy to understand:
80 09 FF 24 09 00 32 31 30 20 cs SET SPEEDLIMIT TO "210"
80 09 FF 24 09 00 20 39 30 20 cs SET SPEEDLIMIT TO "90"
80 09 FF 24 09 00 20 35 30 20 cs SET SPEEDLIMIT TO "50"
80 09 FF 24 09 00 20 31 39 20 cs SET SPEEDLIMIT TO "19"
80 09 FF 24 09 00 20 31 30 20 cs SET SPEEDLIMIT TO "10"
80 09 FF 24 09 00 20 20 36 20 cs SET SPEEDLIMIT TO "6"
-----------------| speed |-----
FOURTH, FIFTH and SIXTH _DATA_ byte holds the speed.
30h = 0, 31h = 1, 32h = 2, 39h = 9 etc
20h = BLANK

3B 05 80 41 09 08 cs DE-ACTIVITE SPEELIMIT in OBC -
Kann man eigentlich auch Text in der Anzeige unterm Tacho anzeigen lassen?

wolfi_b
Das macht doch schon das Resler-Interface -
Ok vielen dank
Werde mir dann wahrscheinlich diesen adapter holen, da die bewertungen einfach sehr gut sind und der preis auch in ordnung geht

Brauch ich für meinen 2004er 318i einen Pin7-8 Connector?* Unsere Seite enthält Affiliate-Links, für die unser Forum möglicherweise eine Vergütung bekommt.

Danke für den Tipp.
Weißt du ob das unter linux verwendet werden kann?
Ich möchte damit eigentlich nur RPM und Geschwindigkeit und so Live-Daten auslesen... -
