Kamera von R8 (Page 1 of 2)

Ich weiß nicht, welche CAN Befehle ich für die R8-Kamera schicken muss. Wenn mir das jemand sagen kann, kann ich die Funktion in das FIS-Control programmieren.

Hi,

Es sollte möglich sein, aber Stefan weiß nicht welche Befehlsequence
auf dem CAN Bus gesendet werden muß, um die Kamera zu aktivieren.

In English, if this is easier for you to read:

Stefan might be able to help you, However, in order to activate the
camera, you need to issue a sequence of commands on the CAN
bus. Stefan doesn't know which sequence is necessary here. If you
know or if you can find out the needed sequence, then Stefan can
add it to the firmware of the FIS Control

So, basically, you want to take a camera
and the above mentioned control unit from
an Audi R8 and implement this into an Audi
A3? I'm not sure if this will work at all
(completely different subject).

To find the desired sequence isn't quite
that easy. You will have to do some signal
analysing of the Audi R8's CAN Bus. I'm no
expert here, but basically you will need
to collect data being sent on the CAN bus
in an as "quiet as possible" enviroment.
There is a lot of traffic on the CAN bus,
since this is where all signals of the
different sensors and control units travel.

"As quiet as possible" simply means you
need to reduce the amount of traffic on
the CAN bus (put control units to sleep,
take out the power fuses, etc, etc). Once
you have data how the "quiet bus" looks
like, then you will have to initiate the
camera function. The problem here is that
there are several commands that will be
sent to the control unit of the camera.
Furthermore the control unit of the camera
will send some commands back.

E.g. something like this ("translated" into english):

Navi--> Camera: Camera, wake up please
Camera--> Hello navi, I'm here, what do you want?
Navi--> Camera please send me your data**
Camera--> Navi, Okay here is your data**
Camera--> Navi, all data sent
Navi--> Camera Okay, thanks
Navi--> Camera We are done, please go back to sleep to save power
Camera--> Navi, okay, good night.

This is a *very* crude example of what will happen.
As you can see, there is a lot of info just to do
some simple things AND you will need to find out
which bits are the data, the start and end blocks
surrounding the data, the init sequence, the handshake
protokoll, etc.

This is definitively NOT a trivial task and not
something that can be done in an half-hour's time
(even if you exactly know what the Audi R8's CAN
bus data looks like).

**data: You will also have to find out if the
data is *video* data or if this data also contains
the distance info. Newer cars use this data, for
example to control the autoranging cruise control
(front camera, of course). I don't know if an R8
still has the ultrasonic transducers in the rear
bumper to provide distance infos while parking or
if they rely soley or partially on the camera.
If you find schematics of the hookup bewtween
the camera, it's control unit and the final
display unit, you can tell if the camera is
sending a simple video signal or if it contains
more info (which would make sorting out the
signals even more difficult). Maybe someone on
the forum can tell us more on the R8 (I'm not
rich enough to be able to afford one ;o))

Hier ist mein Freund die Kamera auf den r8, getvey gleichen)) wollen versuchen, sein Team sehen

hi, the camera had not yet done
have another suggestion
in my country is very expensive at the new rate currency reserve FIS control, because of this, many people refuse to buy for 300 euros, I'll zarabatovayu 500 euros, as we would like to have more users)) which has not only the people (opc ) possible to make a separate block for (opc)? if so, what will be the price?

Thanks Stefan)) found in circuits where soldering circuit elements? Ideally need a project board and scheme
Charges may be one-sided, and maybe 5-6-layered.

Der B7 hat keinen Sensor für den Ölstand. Das FIS-Control kann deswegen den Ölstand nicht anzeigen.

Oh, da lag ich wohl falsch. Ich dachte den Ölstandsensor gab es erst im B8.
Bleibt die Frage, ob man die Sensorwerte irgendwo einlesen (OBD/CAN) oder abgreifen kann.

Gibt es sogar im B5 ab Mj. 2000.
Die Werte sollten in den KI-MWBs zu finden sein.

Wäre aber eine Super Sache wenn man eine Balkenanzeige wie im B8 hätte wo der ungefäre Motorölstand angezeigt werden würde.

Mfg Tom

Stephen Ich bin gestürzt Video, das Sie den Ölstand FIS 1:31 gemacht  http://youtu.be/218uGnlX1mk

Schreib du ihn an. Dein Russisch ist besser ;-)
