I was doing a combined project with a friend, with me on s/w and him on h/w. After a year of coding on my part & not much activity on his, he announced that he is "too busy" to continue.
That leaves me, a pure s/w guy with little or no h/w knowledge to continue. I need a 4x3 keypad which will work with an Atmel UC3 series 32-bit microprocessor - can you advise?
Preferably something with sample code.
As I have no o/s, should I go interrupt driven or polled? (told you I am not a h/w guy ;-)
Thanks in advance for any help.
