    TLCDCEmu v0.2 on sourceforge

    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.

    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 :-)
    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
    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 :-)
    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!
    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?

    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 ?

    And this is the Display
    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 :-)
