I just did it with an arduino. I was wondering how to get the rs232 command to change the audio source. I coulnt find it in the phillips manual.
i need a ttl/rs232 converter to use it with an arduino right?
i just copied the arduino code and modified it to only switch some stuff as a demo but it doesn't work...
Yes , you need something like this one:
