The problem with Elektor articles is they don't usually give you the code, you have to buy a VERY!! expensive pre-programmed chip. >However the AN460 code does not manage the tuning and re-tuning, >so the RDS features that need this (e.g. retuning to traffic >announcements) are not implemented.

As an addon for an existing tuner re-tuning isn't really a very viable option, as you suggested it doesn't do that!. >I expect to need a beefier micro.

Anyway, I've found the RDS code, and I've had three requests for it - so I won't post it to the list, but I've uploaded it to my website in the 'temp' directory. There's no link to it, just point your browser at 'www.lpilsley.demon.co.uk/temp/rds3.zip'. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : nigelg@lpilsley.demon.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.demon.co.uk | | Chesterfield | Official site for Shin Ki Ju Jitsu | | England | | \--------------------------------------------------------------/
