    I am doing a project using pic16f877 and SPO256.the user will enter a password(4 integer numbers or more)using a keypad.
    This integers will be compared to a stored password.
    If this password is correct the SPO256 will say a word(welcome,you are allowed)and a green light will appear(using LED).
    If not another sentence will be said and a red light will appear.
    I know how to connect,but i have to write the code using c language.
    1-How to read the integers from the keypad using pic16f877's port c.
    2-How to compare the entered password with the one stored already.
    3-How to open the green light if the password correct(and the red light)
    Please i don't have enough time,i need a fast help....
