Thread: Renault "Tuner List" Head Unit/CD changer hacking - Controls

Hi all,

I finally opened the TLCDCEmu project (Tuner List CD Changer Emulator) on sourceforge.net : http://tlcdcemu.sourceforge.net

There, you'll find version 0.2 of the Java version I'm using. More information on the website (see particularly the HowTo page)

So this is the last time I upload here a version containing the windows libs here (it's 199K and the limit is 200K anyway :-) ). Future versions will include only the classes and be available on sourceforge.

Please note that I finally switched to RxTx for all platforms, so if you installed the communications libs from Sun, well, you can throw them away and use RxTx ones instead (sorry slimmegane :-)), but the principle is the same if you're on Windows : a jar in the "classpath" (for example in the lib subdir), and a dll in the "path" (for example in the JRE's bin directory or windows\system32).

Also take a look at the screenshots on SourceForge :-)

Enjoy :-)

Hi Vicne,
I've see the screenshot on sourceforce, I've downloaded the .zip attachaed in this thread but when I run the .bat I've this:


C:\Documents and Settings\Slim\Desktop\TLCDCEmu>java -cp ./classes;./lib/RXTXcom
m.jar org.tlcdcemu.main.TLCDCEmu
Tuner List CD Changer Emulator (TLCDCEmu) version 0.2
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7

What? Whit the previous version I've B for boot ecc ecc and now? How it works?

Thanks a lot,
SLM.

OPs, I've found the window... Excuse me...

IT WORKS IT WORKS!!!!!

GREAT VICNE!!!!!!

All ok, I've connect all, connect the soundblaster, set his software, run TLCDCEmu and power on HU, select source and I read CD1 TRK1 ! Play WinAMP and sound after setup volume it work! it work!

A question now When I change track from HU the sound off and If I not change source to FM and return to CDC the sound stay off, other question is: Is possible to close appl from GUI?

Thanks a lot Vicne! Do you have think to a Donate Paypal? If yes send me your address i want to donate whit hope that you can continue to envelope this project and command PC whit Steering Whell of renault!

Thanks!

Great !

Not that I had any doubt but I'm really happy you were able to reproduce the complete setup. It means instructions are not that bad :-)

Oh that's strange. I admit I made most of my tests without SPDIF being connected.
I probably have to actually respond to track changes in a coherent manner. For now, I just acknowledge the message and change subsequent PLAYING frames with updated values, while the original CD changer sends 4 frames in response to track change request : TRACK_CHANGE 1, BUSY 1, BUSY 2, TRACK_CHANGE 2.
The problem is that these frames carry "data" bytes, and I am still not sure what to send for data. I can do a trial and error, but I'd prefer to understand what these data mean.
It probably needs a fresh look to the "rosetta stone" dumps to understand these "21h" and "27h" frames from the CD changer.
HINT >>> HELP NEEDED ON THIS <<< HINT :-)

Other question is: Is possible to close appl from GUI?

Technically, I could allow it, but I disabled it for now because conceptually I don't think it's wise for a plugin to request closure of the full emulator. Like if a printer driver could close Word...
But as the GUI Plugin is designed as a demo, I might change my mind however because it feels so much natural... I always try to close the app that way myself :-)

Well, I didn't think the first tester would want to donate ? But why not. I have setup the SourceForge donation system at the bottom of the HomePage
As for continuation, I cannot promise anything, but I intend to go as far as there's a common interest, the current goals being :
- to bulletproof the behaviour (if the HU is turned off then on, for example)
- to test a JNI plugin to Winamp, either directly or via ATI remote wonder plugins
- to communicate with a front end (I know we're at least 2 using RoadRunner, so I'll contact Guino to get his advice)
- to enhance the plugin architecture, for example with a "plugin router plugin", which would allow for example to have PREV/NEXT controlling Winamp, then press "1" and have PREV/NEXT controlling the Navigation Zoom in/Zoom out ;-)

Everybody is invited to participate, of course, and a lighter (native or PIC-based) implementation would be welcome, for example.

Great Idea! To communicate whit RR I think there is more easy using Girder! it works fine whit RR, I've used whit WinLIRC and a simply IR Receiver.

If I've undestand fine Girder have an open port in local system (127.0.0.1) where you can send command, for example when I click next track from HU your Java plugin send "next" to Girder that send "Next Track" to RR (look RR.GML in RR folder) there is a complete list of command that accept RR.
What think? You can try this?

There is my homemade interface



And this is the Display:

Well, you bet I can try this !
I didn't know it was that simple. Well, of course, we'll encounter caveats, but sending commands to a local port in Java is straightforward thanks to Jakarta Commons' HttpClient. I think I'll go that way and won't bother doing JNI for now.
Thanks a lot for your help. I may come back to you if I have questions because you seem to have experience in that field.

It looks much more professional than mine. May I post it as a "screenshot" on sourceforge ?

Did you try changing the track number in the GUI plugin and click "Set" ? :-)
BTW, I noticed that the display has *two* blanks between the word "CD" and the number "1", so maybe we're not limited to 99 after all (currently, all limitations on Track/CD number and Track/CD times are set in software by the GUI plugin, and I didn't try sending "unreasonable" values, but it might be funny :-)
