    How to program a keypad to work as a mobile phone keypad using PIC?

    Good day,

    May i know how could i programming a keypad extractly like the mobile phone keypad using PIC? For instance, when we first press the 2 button, it is an 'a', second press is a 'b' den is 'c',finally is '2', then it repeat the routine. Same for other buttons. So, the 4x3 keypad can have output for 0-9 and a-z. Please kindly give me the code if anyone of you have it, or at least give me an idea how to program it. Thx in advance.

    mobile phone keypad how to use

    Hi,
    I am designing an advertising stand which will use a mobile phone (with a program running on it) for input processing. To protect it from vandalism and theft, the phone will be hidden within the advertising stand. The users will use a standard numeric keypad for data-entry.

    Question:
    Can the phone recognize key-strokes on the external keypad as digits out-of-the box or will I have to add some code to the mobile phone application so that the phone understands which key on the keypad has been pressed?

    PS: The keypad will be connected to the phone either through USB-cable or through Bluetooth.

    Any help would be greatly appreciated!
