I am trying to write keypad program, I work with 8051 and keil compiler so I did google search and I found so many links . I have read following three links but still I am confuse because the program has been written differently in all the three links and I don't understand how to write proficient program for keypad interfacing.

I don't want to just copy paste the program.I want to write program by proper understanding. I have seen the keypad datasheet and I understand the basic logic but I don't understand how to start to writing program.
Can anyone guide me to write program. If i make program into small parts then which one part's should I make first and then later.
