Thanks Fabian,
Unfortunately I need rather more keys that 0-9 # and * , I want to be able to enter decimal numbers so thats 0-9 and . also to move forwards / backwards in increments on a single button press so thats two more keys < and > also to start and stop moving continuously thats two more keys plus keys to select a couple of operating modes such as selecting the increment etc. So I reckon a minimum of 16 buttons are required.
I guess I could use two pads but I would rather have the buttons in one pad.

Fabien,
I hadnt thought of that, still fairly new to this hardware stuff. Can you get serially driven keypads quite cheaply? In any case I thoght that if my first preference keypad worked out ok, I would dedicate a processor to it connected to N+ serially. My output screen is serial.

Not really,
I am building a stand alone stepper controller for my rose engine, which will not be connected to my network except to download some tables. I got the N+ to use the SD card!! and network connection for downloading. But control of the machine is via keypad buttons.
