    I love you forever

    will try it shortly.

    I've hit another booboo! when I remove the ibus wire from the sound linx adaptor, something happens to the sound. I think the adaptor is usng the 12v supply from the ibus to do something. I'll try to provide 12v from the other wire and hope that this way, I can bypass the adatpor's ibus intrusion, but still use it's leveling capability.

    I would imagine that the adapter is actually processing/sending messages so it may not function properly without the ibus connection.

    When the CD 01- comes up on the cluster that is actually the radio responding to the steering wheel button press. It sends a broadcast message to all modules on the ibus based on the selected source - ie. when CD is selected, you get the CD 01- and station frequency for the FM radio. It's possible that it doesn't do anything when the tape source is selected, but I don't own any tapes so I can't test it. Unfortunately, there really isn't anything that can be done about it. It works in reverse for me, the CD 01- comes up and then the trackname message blots it out.

    Attached is the latest version - nothing new in it, I've just been cleaning up my code a little. (Can you tell my wife has been out of town?!!!)

    works! everything's as I like it now. though I did have to restart ibus comm a couple of times so it can put the cd mode back on. but that's fine. having manual buttons to do those thigns would be lovely.

    another issue I noticed is that when ibuscomm is on, it steals focus. so where I wanted to use notepad whilst it was on, I would only get a second or two before focus would be lost. This also seeps into roadrunner when trying to switch on visuliation/external apps. do u get that at all?

    I think I'll have to install .net soon and get familiar with this code.

    many thanks for your continued support. my g/f also feels the lack of attention from my "other baby"

    If you have the "AppCaptionSendEventTo" control set in the .ini, then prior to sending a keyboard map event ibuscomm will force the target window into the foreground. I just leave it set to ="". Ibuscomm will then send the keys to whatever application is on top, but RR stays nicely in focus for me and hasn't been an issue. (RR & Ibuscomm are the only two applications running on my pc, though.) I did notice in the code that I had implemented the same structure prior to sending the RRCommands and it isn't needed so I'll correct that in the next rev. If you're using just the RRcommands, then that should solve your problem.

    I'll take a look at the need to restart on the CD option issue as well. The current code doesn't support anything other than software contention management (which is basically just a timer) so there are times when the bus might be crowded enough to cause collisions and packet corruption. At some point I'll implement the DSR / DTR contention method which should clear most of that up.

    Glad to hear it's working for you so far (mostly, anyway). It's written in VB6 so you may have to make some changes for it to work under .net - I've got no clue though, like I said, I'm no programmer! Nonetheless, it has been a good learning experience.

    I have the AppCap... setting to "" also. have you tried winamp visualisation at all? that flics on for a second, then disappears.

    Regarding the contention, my ibus does freak out it seems every now and then... or the radio gets overloaded or something 'cos i just hear some beeps through the speakers, then after a while the sound resumes.

    So far it's working as you say, so I'm happy I'm getting VB6 this minute, so I can start messin with it too!

    thanks for all the help, I'll keep you posted with any developments/regressions

    ok, i've done some new changes. they're quick hacks, but hey... they work

    - in the ini file, you can now find a new field. use this to set the startup message of your choice like this: WelcomeMessage=Carputer Initialised

    - added a textfield to the GUI and a submit message to MID button. this way, any external app that needs to send messages to the MID can do so easily

    - added the ability to post IBUS messages directly too, but I've disabled it as it needs a little more work. Some hexing of some type needs to be applied which I don't fully understand yet.

    - also applied some refactoring here and there

    I think that it is not working for an e46. I already tried to send text to MID using ibus analyser but It is not working. I don't know why and nobody never answer in hacktheibus forum....
    Too bad! But the wheel buttons work perfectly.

    u just need to do a bit of monitoring to see how text is sent to the mid, and the format it's given in. why dont' you do this:

    start ibus analyser, and press FM on your board, then press something else like CD, then FM again. do this repeatedly, then try to find which action relates to the message log in the ibus analyser. once you have that message, let me know what it is and I can include it in the ini file as a CHASSIS=E46 option.

    With the current way that it is sending text, it won't work unless you have the high cluster. The text is being specifically aimed at the cluster. If you change the target to a broadcast, then any modules capable of displaying the text will do so. The packet is set up like this currently:

    68 XX 80 YY YY YY YY YY CC

    68 = source device (radio)
    XX = total packet length
    80 = target device (cluster)
    YY = data
    CC = checksum

    if you change the 80 to FF, then it should work. FF is a broadcast message which is normally how the radio sends station information, etc. I modified ibuscomm to target the cluster specifically so the information wasn't sent to my factory navigation screen, just the cluster.
