no basic stamp found

dhcarstens

I recently purchased a MoBoStamp-pe and it was working fine over a couple of weeks.· Now when I try to program it I get a "no basic stamp found" error and a 'can't open port; in use" message shows in the download progress box. It is currently running a program

I tried resetting the board or downloading the loader software again and·nothing helps.· Any ideas?

Thanks for your info. I think the problem was the MOBO was running a program that had DEBUG statements. I turned it off when not in use and when I turned it back on, the program was still running making the computer think it was a serial port.

Working through the suggestions finally did the trick. Here's what I ended up doing:

--pulled the USB line from the board
--reloaded the stamp editor
--reloaded the USB driver
--reset the computer
--pulled the power pin (choosing between USB power and external power to the stamp)
--attached the USB connection to let the USB interface start up (interface is powered separately).
--put back the power pin on USB power, starting up the computer
--loaded and run the program

I'm not sure reloading the programs were necessary.

In the future, I'm going to run a simple program:

' {$STAMP BS2pe}
' {$PBASIC 2.5}
END

before I power down the stamp to make sure it's not running debug operations.
