    XM Radio - COMPLETE REWRITE

    Hi, all...

    I think most of you guys here know me, Im the guy who makes the Sirius interfaces and the XM MiniTuner (NEW) interface... and that simple *** HD Radio Cable

    and if you didnt know, I DONT HAVE A CAR PC!

    I do control system programming for a living (i work for AMX)
    anyway...

    some quick plugs... the Sirius interface is now avail at MP3Car.com!!
    http://store.mp3car.com/category_s/39.htm

    and they will be carrying the XM Direct2 interface, which is USB to XM MiniTuner!!!
    REALLY COOL device, and perfect for CAR PCS

    now back on focus

    so... only have RR installed on my pc to test HDRadio...
    so.. since... i have been working on the NEW XM, i decieded to test it in RR
    only to find it didnt work, and it should have... upon futher investigation
    I discovered that the RR code was basicly SLAMMING the tuner with commands
    in real life thats a NO NO!!! im socked the xmpcr and xmd1000 worked ok
    and then i did more testing, and noticed the xmpcr and xmd1000 dont work that good
    commands for channel data were being missed(too much slamming)
    so... i said... ok, i hate to do this... its VB6 (which i dont know as well as C or C#)
    but i need this to work...
    i got 11-02-2007's source code and took a look... and in a few secs i said ok
    I have to do this and do it right
    I have worked on my XM Control class for 3 years now, and its been working great for a protocol that isnt public.. and when i learn something NEW i fix it immediatly! I'm a believer in continous improvement.
    ok, so to do this right, i dumped all the XM code in RR, and used my .net class as a COMOBJ to do the new version
    of course i no little about RR, and its backend, but when im excited about something im very picky and want nothing less then perfect(as possible)
    some things i didnt like (and dont like about HD Radio/Sirius) in the RR implementation... the fact the tuner goes on and off... in my car(REAL RADIO) when i click on SAT its instant, no wait... its just there... same for HD Radio... with RR, you got a sec or so to wait for the tuner to pop on, and if coming from say HD, wait for that to turn off, then sat to turn on...(some of thats still in play (for now) )
    so after looking at all the code in RR, its massive, so much time was put into this by GUINO... and would love to work with him and improve this... i got a hold of him, and he said he would integrate my changes in release, but his time was limited...
    due to the way RR is written, i had to make subtle changes in other modules of RR
    but they are only XM Related...
    so it works really well on my Virtual machine (I didnt want to install Visual Studio 6, on my real machine )

    im sure its not 100% yet, but its ready for some testing!!! (its in the 90s)

    so what RR does now...

    as soon as its run, it powers on XM and its on all the time... continously
    updating channel data, im also NOT using the cache file (as of now, im debating that)
    there is some technical reasons, but .net class has its own cache

    in my build here, i had to comment out, mappoint, i need to get that i guess or, just get the OCX it reference, so it will build
    anyway...

    im looking for someone, with XMD1000 and XMPCR

    who wants to test/work on this with me...

    I sent it to someone who dont have a CARPC, and he ran it fine...

    ok, i think this post is too big...

    SURE

    we just need to hook up, id like to work with whom ever
    now since i assume most people have their CARPCs in the CAR
    it makes it harder to work live

    id like to do chat via MSN Messenger... and summary what u have to do
    the only thing (i think) you have to do to save what you got
    is just back up RoadRunner.exe

    i have a new directory "XMRadio" which has the control class (like the HDRadio)
    and a new EXE remember its without that Mappoint program
    (until i get i guess the .ocx)

    who ever is interested PM me...

    im not real busy, but got to sleep tonight... so i think the weekend is the best
    (friday night ---> )

    man i hope you get this working.. i took a brief look at the xm code in rr, and while it works.. it seems to be very clumsy... and i have definitely noticed that the channel information pops in and out irradically. I wish i could test but i'm kinda stretched for time now. Guess my post was just donet o show support of this new effort you got goin. Thank you mitch!!!

    Very pleased to hear Mitch is working on making our radio experience much more enjoyable in Road Runner. I had always thought it shouldn't be necessary to wait 5 seconds after you press the radio or XM buttons to actually get music.

    I have both the XMPCR and XMDirect as well as HDradio. I do not have a sirius unit.

    That's the only thing I don't like about the HD Radio. When you click the button in RR it takes 5 to 7 sec to start playing. When you switch from Mp3 to Radio and back, it should be instant...

    Not rushing anything Mitch. As of now, I can live with it.
