    Hi, im very new to this any help very much appreciated.
    I have several pieces of test equipment that plug into a base station for charging and downloading. Each unit has a pic 12f629 microcontroller inside. This microcontroller sends a unique identity code to the base station.
    The microcontroller only connects via 3 wires 5V+ 0V and a data wire. The identity code is repeated continuosly untill the units are disconnected. If i connect an LED to the pic output it flashes as if its a coded signal. If i change the pic from one piece of test equipment to another the codes change.
    I would like to be able to read the unique identity code. Perhaps using a Stamp microcontroller with a display. or a PC.

    Any help or ideas welcome

    It is probably sending serial data. More that likely ASCII. This is vey easy to do with a PIC. I is also easy to read it with a PIC. You can also send the data into a PC with an
    RS232 interface IC (MAX232), and read the data from there.
