Hardware not found

viking

I did a search on the forum for this but came up with nothing. Basic Stamp 1 Rev DX I get a hardware not found when I try to load a program. I am using the Parallax supplied cable. Had a 7.5Vdc wall wart then changed to a 9V battery to the clips. Same error. Help

Which editor are you using?

I was using the dos program. I cannot find a v # It came with the starter kit a few years ago. That was the one that gave me the error. That was in my old laptop. I am going to load the windows software into it now. V2.2.6 ans V2.3.8· I will try the v2.3.8 as it is probably the newest.

The dos editor is version 1.0

The DOS editor requires a parallel port for programming. You will be much better off using the current Stamp Basic Editor which uses a serial port for the BS1 along with a serial programming adapter for the BS1.

If you're using the parallel port programming cable, the DOS editor should work. Make sure it's wired correctly to the Stamp and the power is on.

I have both cables supplied by Parallax since I use the windows program with my main pc. I use the serial port on it. I had used the parrell port on my laptop as I was using dos. That is what I had to use before· the windows program. Funny my lap top was opening the floppy ok then all of a sudden it would not open the editor. One problem was a CHEAP battery only putting out 1.2V was suppose to be 9V

I am using a wall trans. of 7.5V dc I wired it to Vin and Vss. I just tried another stamp I had here and it loaded ok using the serial port. I get confused with the windows editor such as V2.3.8 I cannot find the

····· LOAD like I have in the dos editor. Just RUN· Does RUN load it into the stamp also? I am afraid I may have damaged the original stamp somehow.I would think the thing would have reset by now from low voltage. Thanks for any and all help.

Mike Green

When you do RUN from the Windows Editor, it loads and executes the program.

If you try to use a serial port for programming a BS1 without the proper adapter, you can damage it.

Yes I have the adapter. I ordered it when I down loaded the editor. It came directly from parallax. I also ordered a new cable with it to make sure I was up to snuff.

Well I tried another stamp and it loaded ok and was working using a 9v battery snapped in.Oh good I said. I then started to wire it to some ssr's. I checked one in the beginning still using the 9v battery worked ok. Then I wired in a 7.5v wall trans which was putting out 9.8 to 10V I wired the + or positive side to theVin terminal and the - neg. to the Vss terminal This is a basic stamp 1 Rev Dx I have wired others up and worked ok. I do not ahve them here as these are used in xmas displays and I only work with these 1 time a year. Am I wiring the transformer to the correct terminals? Light up night the 29. I am in a bind.·

I forgot to mention that I am using editor V2.3.8 for windows and using the factory supplied cable and adapter. I have the 2 arrows matching on the same side. The first thing was after I plugged in the trans. I seemed to have lost the program. I am trying to load it back in using a 9V battery and I keep getting the message·( no stamp found)

Mike Green

What you describe should work. There must be some difference between what you said and what you actually did. Did you check the polarity of the output of the wall wart? Measure the voltage at the Vdd terminal of the Stamp. It's the output of the regulator on the Stamp module. The voltage should be +5V when power is applied to Vin and Vss.

· Well stupid be stupid is. I always check the tabs on the jacks I solder in to plug the wart into. The last ones I got looked like all the rest buuuut they were differant. So I had the neg. to the vin terminal and the plus to the vss terminal. Needless to say that will not work and caused me to blow 2 stamps. Thank you thank you for all your help.
