Renault "Tuner List" Head Unit/CD changer hacking - Controls - Page 34

Well, apart for adding links in the above post, I hadn't much time the other day to explain the benefits of the last version, so here we go :
I think the contextual plug-in is a huge leap forward. Here is the scenario implemented in the config file :
- Upon startup, the state is set to 'STATE_MENU' (RR is most probably on its MAIN screen)
- By default, NEXT/PREV (stalk controls for example) go to NEXT/PREV track.
- If you press button 2, RR goes to the AUDIO screen (tracklist). NEXT/PREV still have the default behaviour.
- If you press button 3, RR goes to the GPS screen (MapMonkey) and the emulator switches to the state 'STATE_GPS'
- Now, in 'STATE_GPS', the NEXT/PREV (same stalk controls) are now mapped to zoom in/out
- If you press back button 2 or 1, then the emulator leaves the 'STATE_GPS' and default behaviour is restored
- If you press button 6 while in the AUDIO screen, RR switches to the GPS screen for 5 seconds then comes back to AUDIO automatically

Using this feature, one could really elaborate a full multi-level navigation menu.
The first problem is the fact that NEXT/PREV causes a systematic mute, and it's really not convenient to have the sound muted each time you zoom in or out, so it's a pity but I'll probably stick to the front panel numbered buttons and will leave the thumbwheel mapped to NEXT/PREV TRACK...
The second problem is feedback, but ...

I think there's a solution...

Anybody knows of a free, good, multilingual text-to-speech ?

festival (never used it though, multilingual as in English, Spanish, Welsh).
See also Speech synthesis on wikipedia.

Mmmmh... no French - and no Italian or Dutch either :-(

Good starting point indeed.

SAPI 4 (MS only) looks cool, but it's a pity that "these text-to-speech engines are licensed only for use in Microsoft Agent enabled applications and Web pages with a visibly displayed Microsoft Agent character" :-(. I don't want a dog in my car, it will put hair everywhere :-)... Plus, it's Win-only.

MBROLA seems really versatile (25 languages) but the learning curve clearly is much steeper. It is only a phoneme renderer as I understand it and you need a separate Text > Phoneme converter such as Euler...

Moreover, it seems MBROLA can be used as the backend for the Java FreeTTS, so we might have all the bricks in hand...

I need to look further into that...

Thanks for the Wikipedia tip.

I have a VDO 603A cd changer, I want use a Atmage16L to simulate the CDC.
I have test the Atmage16L with a max232 connect to PC's RS232, it seem it work finally, but when I use the UART port of Atmage16L to connect to CDC , and want test could it get CDC's data. I can't get any data form the CDC's.

Maybe Atmega16L?

Anyway looking this pdf :

http://www.vdodayton.com/sycomax/uis...2005-GB-oB.pdf

I don't know what that features means:

Digital and Analog BUS (switchable).

maybe you have need to switch somethink?

Sorry, I'm not really sure I understand what you want to achieve...
The most classic use is for people who don't have a CDC and want feed sound their HU.
So you have a CDC and you want to connect it to a PIC ? What's the point :-) ?

Putput · 04-14-2006, 05:51 PM

I finally finished the hardware part, inspired on this design and with Vicne's software and it worked! The display showed TR1 CD1 and the PC exchanged telegrams with the HU, so far so good.

Then I connected the SPDIF to my VIA SP13000 board and guess what, no sound!!??

What did I do wrong? Could it be the SPDIF connection, I only used pin 18 and 19, 20 is not connected? Or could there be a difference in Update List models and Tuner List?

I admit I have no idea if there are differences between Tuner List and Update List models. Although, it seems the same CD Changers are compatible with both I'd be surprised if they were different in that regard.

A few tests to perform, maybe :
- if you use NEXT/PREV on the stalk controls, does Winamp change track ?
- if you use PAUSE/PLAY, does Winamp follow ? Note that if SPDIF has been disabled in the HU for a reason or another, a PAUSE/PLAY cycle often re-enables it.
- do you have a means to test the SPDIF output of your SP13000, to make sure there is something actually coming out of it ? Please note that for the M10000, there is a typo in the manual that gives the video/spdif jumper settings wrong.

You're not far away, I'm sure... Good Luck

Thanks for the tip!!! Now I remember!!!

I must change a jumper on the board to enable SPDIF, default this output is used for Video Out, I remember that I used the Video Output once so the jumper must be in the wrong position.

Yes, factory settings is video for all Epia's I think.
Now it'd have been fun if you had seen video on your HU :-)

I'll be more then happy when I know that nothing is damaged. But it will have to wait until tomorrow. Wait and see ... Hopefully no video on the HU but audio from the speakers

I changed th SPDIF jumper according to the manual, installed everything and made a new test. Same result

, software works ok, I've changed the debug level (+) and see that telegrams are being exchanged between PC and CDC but no audio.
A question, when I try to change the volume in CDC mode, and playing frames are send to the HU nothing happens, shouldn't the display show the volume level when changing? It does this in tuner, AUX and CD mode but not in CDC mode, is this normal? And the volume level isn't changed so I assume that the audio input (SPDIF) is not yet activated. I also remember that the first version of the Connects2 adapter was not compatible with Update List models, their new version works on both types (Tuner and Update) but this was not always so. Perhaps the Update List model doesn't accept sending 00 as playing info in each frame? Vicne, is there a simple way to change your program so that it sends real playing info?

:-(
Just to rule this out, do you by chance have another device with a SPDIF output (DVD player) to connect to the HU or or one with a SPDIF input (receiver or home theater amplifier) to connect to your Epia...
I'm almost sure the problem isn't there now, but you never know.

No it isn't. Volume changes should be shown on HU display indeed...

I didn't know that.
Obviously, it means there *is* a difference between TL and UL head units :-(

Well, I don't want to disappoint you but there are many reasons the SPDIF could be de-activated. I can see a few options to try :
1) to answer your question, yes, there a simple way for the program to send real playing info : just use the LogicalPlugin : see http://tlcdcemu.sourceforge.net/plugins.html
Time is incremented every second, CDs are declared of 20 tracks x 3 minutes, and tracks change automatically. I advise you to activate only LogicalPlugin and GUIPlugin instead of the RoadRunner one (there might be conflict if you activate both).
2) Before you change that, did you try PLAY/PAUSE/NEXT/PREV and numbered buttons ? Even if you don't have RR, try with the GUIPlugin... Are the commands sent ? Doesn't a PAUSE/PLAY activate SPDIF ?
3) You might have more luck with Pippolippi's emulator. By luck, we took different approaches (full vs simplest) so it could well work
4) If you want (me) to debug further, it would be interesting to have the full log of the startup sequence. To do that, just append '>tlcdcemu.log 2>tlcdcemu.err' to the first line of TLCDCEmu.bat, so that it looks like :

Code:

java -cp ./classes;./lib/RXTXcomm.jar org.tlcdcemu.main.TLCDCEmu >tlcdcemu.log 2>tlcdcemu.err

then run the program with maximum debug Level (6) for a full session and then post the two log files...

Note that there is a non-zero probability that we won't be able to go further without spying on a UL Tuner list connected to an actual CDC or a Connects2...

Let's cross the fingers.

Note that I don't know if my program actually enables spdif input since I don't have an spdif source to test with, and in the coming months I will be busy with other things

Putput · 04-17-2006, 01:44 PM

My first guess was the right one, UL models 'need to see progress' when the CD is

. I managed to get the sound enabled with the logical plugin! Only problem was that after I switched the HU off and back on again the sound stayed off. But I'm one big step closer, UL models seem to control input data from the CDC changer more accurately. I need to do some more tests to see what is needed to enable sound. Now the only thing I need is time .... does anybody now where to find some ...

(Yep, I can smile again)
