I'm working on a project to implement a handheld version of the game Nim for fun. The game would have two button inputs, one for editing the number you wish to take from the pot and one for submitting your move. The game would then move to Player 2 and you'd hand the device off.
I've never done any work with micros (besides arduino and that doesn't involve designing around the micro) in my electronics design so I'm a little nervous about it. My schematic is attached. I'm thinking of using the extra I/O to implement an optional FRAM interface in case the on-board 2k isn't enough for my program.
EDIT: Forgot to mention the 6 pin ISP interface. I know I won't be able to use certain ISP programmers that use 5V from the programmer since this is too high for the display. Luckily the atmel programmer relies on board power.
