    @BeamrRider: Did you ever get this library coded/debugged? I was checking google to see what was out there and only came across a partially implemented libarary in sourceforge. Unfortunately, it doesn't yet implement error correction so it isn't going to be too useful. The essenginer freeware application should be immensely helpful for debuggging.

    I need this code for Seth's radio project. The tuner ICs to be used will output the demodulated RBDS/RDS bit-stream and clock. These are TTL level signals and are directly comppatible with most modern RS232 recievers without level conversion. Worst case I'll toss in a max232 family IC for level conversion.

    I'm happy to toss a simple GUI front end on whatever you've got. Thanks for any help....sorry for reviving an old (and hopefully not dead) thread.

    @BeamRider a member of carmedia has a usb radio with RDS decode in developpement...

    Could it be possible that you share the source code of your software decoder library?
    Epia M9000, lili 7" vga&touch & 2xTM-7002S compo, camera with reversed image, 2.5" 60 GB, 256Mb DDR, Opus 90W, GPS usb... AND MEDIACRUISER of course!

This version of the library is not very clean nor readable but it's working. Major features are:

    - Basic RDS decoding: AF, TP, TA, PTY, ecc (AF can't use grouping by now)
    - Pluggable interface "streams" (COM and Logfile implemented)
    - Pluggable ODA classes
    - TMC decoder(ODA plugin): not completed, but able to decode single mesages, locations and events and much more ...

    I've built two simple MFC application (console and windowed/MDI) to test my library and I'd like to hack a D-Link radio instead of the Clarion HU that I'm using now.
    My wish is to obtain an RDS capable tuner GUI (guys, I don't like GUI programming) and to be able to have TMC messages in Destinator via its SDK but I'm not sure if it'll be possible, maybe with V3.....
    Someone wants to add RDS/TMC in its project?
    Beamrider.... a post from the past but is there any chance I can get a copy of your app / info ? I have a TMC receiver now and would like to make use of it.

    Cheers

    Some time ago hex was floating about to re-program it with that made th sub 99 years.......

    almost makes me want to go to the scrappers to rip 1 out of an old xantia/vectra/astra

    But, as the unit receives all the info just does not act on it, its already receieved it so tapping that data off to a software decoder is viable.

    keep meaning to build an interface for my old (battery portable) one and then go sit under a tower at rush hour to see how the data changes with trafiic movement etc.

    1) The Traffic Master data - all of it..... via the Vodafone paging system if I rember using a version of POSAG

    2) http://www.cartft.com/catalog/il/392
