Are there any specifications on the CD-I pad available somewhere? Pinouts or anything would be appreciated.
You can find some info inside this archive: http://www.alpinecom.net/phackmann/cdiadapter/CDiGamepadAdapter.zip
SOME info? That was exactly what I was looking for and so much more. Even a working code example, so I can modify that to fit my microcontroller instead of writing from scratch. I've been searching the net for a week for something like this. Thanks a lot!
