Great idea to use this pin in both ways. I'd love such a solution, but
as many others I don't want to open my jukebox and solder it, at least
until warranty runs out. But I don't have any problems to build my own
remote with a µ-controller. There would be many great applications, a
interface to a car stereo for example that displays song name etc. in
the display...
My suggestion for the communication is the following: leave the
remote-pin of the archos as an input all the time, except the remote
sends a special "give-me-data"-command. Only then the archos should
change the port to output, send the requested data and change to input
again. This way, you can use the standard remote as well and there won't
be any situations where both units try to send data, which wouldn't be
very nice (imagine one device trying to pull the line to "1", the other
one trying to pull it to "0" at the same time!). The negative side is,
that all data has to be polled frequently, but I think it is not too
much work for the archos, handling this every 500ms or something like
this...
What do you think?
