Hi BeoWorlders,
if any of you is interested in a IR library for transmitting B&O codes with an Arduino board: I have just created one and uploaded it to GitHub. 🙂
Took me some time, especially because of the high modulation frequency and the B&O unique protocol. It is working quite well and seams to be the only one out there for this purpose at the moment...

You are welcome BeomotionI am not an apple fan, sorry.Thanks for the praise. @olvisab: what especially do you mean with that? Which combination of devices?
Could these codes also be used for receiving B&O IR codes with an Arduino with en IR receiver?

Interesting, thanks for your effort!

I'm actually working to build B&O receiver to control some kind of system with a B&O remote
like a MP3 player connected by aux input to my beocenter etc...
it's like a B&O receiver with relay output.
Build an emitter is easy because we can program the microcontroller counter to make any frequencies we needs but the problem for the receiver is the 455KHz carrier frequency.
The one used by B&O is not a standard like the 36 or 38KHz used by IR/demodulators available on the market.
so i've build an IR receiver based on the 455KHz circuit from the beocenter diagram. (based on discrete components and 455KHz filter available at Farnell) and perhaps one based on the hard to find (obsolete) U2506 chip
(perharps another good way can be the use of the datalink interface from the beocenter but I must make some back engineering on the protocol...but i have storage scope)
If it works I let you know ;)
