I am confused to interface a 4x4 keypad with 89c51. What, precisely, is confusing you? There are many previous discussions here, and very many examples all over the web - what have you tried so far? Please help me in writing code in C language. Again, what exactly do you need help with? How it will possible to drive a 7segment display with keypad? Well, you can't drive a display from a keypad - obviously! You need to consider three steps: 1. How to handle the keypad; 2. How to handle the display; 3. How to create an application that uses both the display and the keypad. Again, there are many previous discussions here, and very many examples all over the web - what have you tried so far? |
