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

Vicne, i need your advice

I am testing to use an ipaq to run the java CDCemu version
my ipaq (rx1950) has windows mobile 2005, insignia jeode java virtual machine
and i found on http://republika.pl/mho/java/comm/ the rxtx libraries for Windows CE and the IPAQ
i tried to modificate the TLCDCEmu.bat to adapt it to the windows CE example(if yo download the RXTX_iPAQ_0211.zip file inside comes all the installation instructions and a .lnk file similar to the .bat used on cdcemu)

yourapp.lnk
54#\windows\evm.exe -Djeode.evm.console.local.keep=true -cp \windows\Programs\yourapp.jar;\windows\lib\comm.jar;\windows\lib\jcl.jar
YourApp -V

TLCDCEmu.bat
java -cp ./classes;./lib/RXTXcomm.jar org.tlcdcemu.main.TLCDCEmu
pause

i adapted the file in the next form:
54#\windows\evm.exe -Djeode.evm.console.local.keep=true -cp \classes;\windows\lib\comm.jar;\windows\lib\jcl.jar TLCDCEmu -V

but i only obtan an error: java.Lang.NoClassDefFoundError:TLCDCEmu
Can someone helpme? do i have a syntaxis error? or its more complicated and do i have to modificate the java source code?

Thanks in advance

If you can find one, then you should probably take a look at the homepage of the project, but also on the FAQ and hardware pages.



Well, I agree that this thread becomes rather long (more than 600 posts) and that it's not easy to find accurate information, but I'm afraid adding one more post of summary would be useless as it would get buried as new posts come in.

The pages given above were written exactly for that purpose.

If you still have questions after reading these pages, don't hesitate to ask.

Best regards,

Vicne.

Little offtopic about sub-out.
I have "Tuner List" (22DC277/62) and when I am looking at this site I still can not figure out if it is possible to connect external amplifier for my subwoofer...? And how?

Foldesa:

Thanks, I had already looked at the Recommended Transformers, but they only list manufacturers and not models, and once on the manufacturer's site I was unable to locate any actual transformer since I don't even understand what exactly they are supposed to do.
Unfortunately both my online suppliers don't have the alternative PE-65612, so I'd like to ask you where you got your parts? Perhaps I can order them from the same place since they also seem to be cheaper.
About your 19meg file, my friend tells me they compress really well, have you tried compressing it to see how much space they take ?
Thanks a lot.

Well, FroMage I don't know the exact part numbers. If you read the data sheet for the recommanded trs then it clearly describes what feqs and resistance, truns etc it must be. You have to ask your supplyer if they have a tr that meets these requirement. Personally I have ordered a sample form scott corp for free

I'm currently implanting this to Eagle, and it will be mutch smaller.

...maybe simple line-out? I can't wait to hear my subwoofer
please help
thx

I'll make a long answer to compensate for your waiting time :-)

That is absolutely normal.

For a java program, the command line typically includes the following things :
- the java virtual machine (JVM) executable (looks like 54#\windows\evm.exe in your case)
- some options to the JVM
- the so-called "classpath", which tells the JVM where to find the code to execute, called classes (libraries or your own code). They can be either plain directories or zipped in "jar" files. In our case, the classpath needs to include the rxtx library and the actual emulator part
- the name of the "main" class to start (entry point of your program). This class can be part of a "package" (the "org.tlcdcemu.main" prefix in our case). Some prefer to write code where the entry point is not in any package like in your example, but I don't :-)
- some options to the program you want to run

So, in our case, I think the line would be something like :

54#\windows\evm.exe -Djeode.evm.console.local.keep=true -cp .\classes;\windows\lib\comm.jar;\windows\lib\jcl.jar org.tlcdcemu.main.TLCDCEmu

It looks like the "-Djeode.evm.console.local.keep=true" option of the Jeode JVM instructs it to keep its output on screen, which is useful when debugging. When it works you can remove it...

For the classpath, first note the dot (.) before \classes. It tells the JVM that it has to search the classes subdir *relative* to the place where your lnk file is. You can replace it with a full path like \windows\programs\TLCDCEmu\classes - without a dot at the start this time - if you like (depending on where you placed the files)

The Rxtx library I had on PC included the JCL library if I'm not mistaken, but if they are separate in your distribution, you have to include both.

And finally "org.tlcdcemu.main.TLCDCEmu" is the class to start

Can someone helpme? do i have a syntaxis error? or its more complicated and do i have to modificate the java source code?

Normally, Java is "write once, run anywhere", so no modification should be needed. In this particular case however, RxTx history has made them change the package name between versions from "javax.comm" to "gnu.io", which makes different versions incompatible unless you modify the calling code. I don't know which package is in use in the version of RxTx you got, but let's try with that first, and don't hesitate to tell us how it's going.

Yeah Eagle is exactly what we want ! You're amazing. I've tried the way of the free samples, especially for the cs5330 (14€ here), but they don't give samples for these, only the 5343 which is similar except i2s output format (which the 8406 supports i think) and 24bit sampling (which i hope will work). Some restistors and such are a bit different, but I hope I'll manage. BTW, I've noticed that the 5330 advices some 1k resistors on the digital outputs, and the 0.1uF condo on the analog input is supposed to be between the 0.47uF condo and the cs5330, does it matter ?
How did you get samples from Schott ? I sent an email to the sales contact because I could not find a link on the site to do this. I'm starting to wonder in which country you live, you certainly cannot be in the US with a Renault car, can you ?
Vicne: I'm starting to feel guilty of hijacking this thread to a different topic although related, do you feel this way and do you want us to move to a different thread ?

What ????? 14 euro for the cs5530. I can't belive it. I live in Hungary, Europe ( you had to see the riot on tv ), and cs5530 is 1400 Huf witch is ~5 euro.
Try this link: http://www.em.avnet.com/memec
I got the samples because my company sometimes makes order from them.

You have to rewire the cs8406 if you put an i2s A/D ic. And probably modificate the op amp too.
