Hello All

I am looking at using one of these boards for a final year university project. I am very impressed with the budget side of things, but I have a few concerns over possible I/O with the board.

Looking at the schematic I can see there is an EXT connecter which has 34 pins. Besides the three pins for power and ground are the rest free to be used for I/O?

I am wanting to connect up a touchscreen, a keypad. and an LCD dispay.

Any comments are greately appreciated on how to proceed.

If you look at the schematic you will see that there on the EXT connectors are all ports which are not connected to CS8900
take care as some of them will be not available during debug as used by the JTAG interface
