As the subject says, do we have anyone that has some experience decoding the Märklin digital protocol with an AVR?
I am trying to make a signal (or semaphore) controller for Märklin model trains, and I have it working most of the time. Have a look at my preliminary page for further info and a couple of videos: http://www.ejberg.dk/trains/signalbrake/index.html
Unfortunately, I am experiencing some sort of periodic instability in decoding the digital format. And quite frankly I'm totally lost right now. Don't know what to try next. So if anyone have been through the problems implementing a Märklin digital decoder, please raise your hand now and say "Yo" :D
