i don't know your application So make clear what assumptions/guesses you are making! that leaves you with 5 port pins. You don't know how many ports he had to start with, so how can you know how many pins will be left?! He might easily be using a derivative with >4 ports... it would be a better idea to use a AT computer keyboard(only two port pins - Sclk,SData) or RC5 remote (only one port pin) to save port pins. and there's plenty of other serial interface options... |
