    What does it say when you click on "Run" and "Identify"? If you have a multi-meter please measure:

    Vin to Vss =
    Vcc to Vss =
    Rst to Vss =

    Let me know what the measurements are?

    Are you able to remore your port directive? If so, this most likely what is causing the issue.

    did you mean remove the line "$port COM1" in the program ?

    i try, and the stamp is not found, but the message is different :

    just "communication error no stamp found"
    eccos and loopback are yes.

    the try was done with a new battery

    thanks for help

    measurments done

    try with a 7.5 v RC car battery

    Vin to Vss = 6.05 V for the second measurment, but first measurments was 7.5v i don't undestand why the value change, because nothing change (same battery, same connection)

    Vcc to Vss =0.669 v
    Rst to Vss = 0.033 v

    thanks from Belgium

    The Rst should be 5v. This is likely the issue. Where did you purchase the BASIC stamp from?
