Hi, i am new to ucontroller programming. I wanted to make some password and 7-segment display projects using 4x4 matrix keyboard as input, in C. I just need some simple example links or sample code or part to understand how to decode the keypad inputs. Thanks in advance.
just a bit of help
keys must be debounced

You can use the Keypad encoder IC such as DFL-KEY55A or DFL-Key55B, which can convert the key pressed to RS232. Click on www.dafulaielectronics.com
