Dear Friends,
Right now I am using 4 key to perform the operation like UP, DOWN, OK & EXIT in my project. But Now I want to perform EXIT operation by remaining three keys. How can I prepare the code???
I mean I want to reduce the keypad from 4 keys to 3 keys....
I am using PIC16F877 with hi-tech C compiler..
Thank you,
