Hi All I'm looking for a keypad program in c that uses the 74c922 encoder chip. A 3x4 keypad is used. I'm really struggling with this. Can anyone help me? How do you wright the program so that the eprom can tell what keypad has been pressed according the encoder chip? Any help would be greatly appreceated! Regards
"But how do impliment the code to tell it to look for the data there?" You don't need to implement any code yourself. Just crosspost your question to as many newsgroups as possible until someone does it for you. What could be simpler than that?
