Hi following is the routine i found at net for 4x4 matrix keypad in C.
www.8051projects.net/.../8051-programming.php
can i use this to display digits using the keypad inputs or do i need any keypad numabers matrix to be assigned?. If yes, Can sombody reply me the simple main code[while(1)] to monitor the key lets say if 5 is pressed then make P1 as high or something like that?. I just want to display digit 5 using keypad.
Thanks in advance.
