    Pardon me, but you will not get many replies if YOU USE ALL CAPS!! THAT IS SEEN AS SHOUTING! (And rather rude.) "Hey, dude" irritates people, also.

    Second, do you want to use an 81555 or an 8255? And do you want help with writing the program, or do you want someone here to write it for you? (The second option will probably run you into some money.)

    Finally, have you read] the data sheet for the chip you want to use (8255/81555)?
