BASIC Stamp

Windows

Editor.

Because the Windows editor supports more than one model of the BASIC Stamp, it is necessary to tell the editor

which model you are trying to program. The STAMP directive is a special command that should be included

(near the top) in a program to indicate the model of BASIC Stamp targeted. The line below is an example of the

STAMP directive (in this case, it indicates that the program is intended for a BASIC Stamp 2):

' { $STAMP BS2 }

This line should be entered into your code, usually near the top, on a line by itself. The STAMP directive is read

and acted upon by the BASIC Stamp Windows Editor any time a source code file is loaded, tokenized,

downloaded (run). In order to test communication between the BASIC Stamp and your PC, download a simple

program as shown below.

' { $STAMP BS2 }

DEBUG “Hello World!”

After you’ve typed in the program, download it using the ► button or the Run | Run menu. If it worked, you’ll see

a blue “debug” window which displays characters sent by the BASIC Stamp to the PC for display (Figure 10).

Communication Problem? If the PC didn’t successfully

communicate with the BASIC Stamp, you would have

received an error message similar to this one.

Troubleshooting suggestions:

• Check power supply and serial cable connection to

• Disable any communication port devices (Palm

Pilots)

• Use CTRL-I to “identify” the BASIC Stamp. Put the
