    5 key USB PIC keyboard

    Hello!
    I have to make 5-key USB keyboard using PIC microcontroller for my school project. Keyboard also must contain switch and potentiometer for volume contol (this is optional).
    When the switch is in state '0', those five keys should represent 4 arrow keys (up, down, left, right) and Enter key as on normal PC keyboard. On the other hand, when the switch is in state '1', keys should represent numbers 1,2,3,4 and 5.
    I have no experience with PIC-USB-PC interface. Schematic is no big deal 'cause it's quite simple, but when it comes to programming there is a huge problem. I don't even know how to start
    I read somewhere that would be easier to make PS/2 keyboard with PIC and then use a PS/2 to USB converter. I really don't know

    So.
    Can you recommend me some projects,ideas or anything.

    I usually use ISIS Professional to simulate circuit, and microC or microPascal for PIC programming.

    Cheers!

    Re: 5 key USB PIC keyboard

    for that you need to understand microchip's free usb stack and modify the program. It is simple if you can understand the communication between pc and the usb device
