Title: Full FIS Cluster Welcome Message
Post by: adam- on November 18, 2014, 12:18:41 PM
Hello there.

I've just bought myself some full FIS clocks for the MK4 and they're diesel ones.  Will need an EPPROM for the petrol ones but that's not really a massive issue just now.

I know you can enable the welcome message on these, same as you can lit needles etc, but does anyone know how to change the actual message?

So instead of it just saying "Welcome!", you can have it say like "Hello, Adam."

I'm gonna pull the binary off the clocks and search for the word welcome in ascii and see if that reveals anything, but that's about as far as my dis assembly knowledge goes.

Thanking you!

I like the sound of this! Slightly off topic, but does the top half display anything without the stock headunit?

Yes, errors

Yes, errors
This made me laugh more than it should have.

My C5 A6 doesn't display anything with the radio removed... The cluster does report a DTC (unable to communicate), but the display is actually blank.
It does the same thing with the climate controls removed too, just blanks the temp readout.

Hey Adam, have you gotten anywhere with this yet? I have a full fis on the side, maybe I can help searching. Needle swipes when you turn the ignition on would be awesome too  ::)

Nah man, I don't have the ability to disassemble the firmware.

On another really helpful board, I posted the same question and was given this:
Welcome text are compiled in display processor Firmware. :( A easy way to change message without reengineering exist not. With external electronic via 3LB or CAN is a individual message possible.

So maybe it's possible to do with CAN?

Hmm thats too bad. I am playing with the idea of attaching a small computer, like a raspberry pi or arduino to input signals. That way you could also send egt and lambda signals to the screen. Like the FIS-controller, but then cheap :P
Still clueless how to actually visualize anything on the fis though (i havent even looked into the wiring yet)

That's pretty cheap tbf, but the listing has ended.

I'll put some money away and probably invest in one, it's a good idea! :)

It's actually not that hard to use a small canbus enabled microcontroller to do this:

I just did this with my STM32F429I-Discovery (ARM based microcontroller), mainly to do canbus experiments, but it's also providing steering wheel controls to my Android tablet (my head-unit) via USB "keyboard".

A simple "welcome" message could easily be done with a Teensey 3.1 and a CANbus transceiver board.

hello :) can you send me to PM which  CAN ID you use for this message? :)
