I have recently started to port/develop a little digital I/O driver for the Icecube for a Linux driver training course. It allows to configure some port pins for output and input with interrupts and with a few jumper cables you can toggle the pins and trigger interrupts. It's still in a preliminary state. Nevertheless I could send it to you in a private mail in case you are interested. Wolfgang. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
