i just got my BASIC stamp 2 OEM... and now i trying to download some coding into microconroller..

but 'no BASIC stamp found'..

for more information.. i just connect microcontroller via USB to Serial connector..

i just new with this program... this microcontroller need connect with power supply first?

How do I connect the BASIC Stamp to my computer for programming?

how i know my basic stamp is power turn on?

    In order to be "found", the Stamp must have power and it must have a proper serial connection. Not all USB to serial adapters will work. Also, you have to have the proper USB driver installed on your PC. If you are using an adapter sold by Parallax or FTDI (the maker of the chips that Parallax uses), you can find the driver on Parallax's website.

    The Stamp has a loader built into the microprocessor chip that talks to the PC when the microprocessor starts up. That's what the PC expects to find, so it needs power to run.

    There are three fairly typically causes for a "No Basic stamp found" error message:

    1) As Mike said: no power to the board.

    2) If you're using a USB-to-serial adapter it may well not be compatible with a Parallax board.

    3) The stamp may simply be plugged in upside down. Check to make sure the shapes on the stamp align with the shapes printed on the board.

    A fourth possible reason is that the stamp or the board are "cooked" (as in burned up.) But that seems highly unlikely since you haven't uploaded any program code to the board/stamp yet.

    My best guess is #2: an incompatible USB-to-serial adapter. The adapter Parallax sells (which we also use) is dependable and affordable. If you order one, be sure to order the adapter that comes with a cable:

    As the BS2 OEM is a kit, there's a lot at stake here - component placement, soldering. Everything has to be right.

    If you have a friend with a working BS2 configuration, then try your board with his setup. That will tell you if the problem is the board or the cable. Consider posting a high res photo of the board here. We might spot an error in assembly.

    thank guys.... i still to find the right power supply to connect with my BS2.....

    but lately i try to connect with my multivoltage adapter....i choose 4.5v.... but like it not function....

    this my architecture of radar circuit...

    Proper voltage is important. If you are using the Vin pin to supply power, you will need at least 6V. If you are using the Vdd pin to supply power, you will need a 5V regulated supply. The PING requires regulated 5V which it can get from the Vdd pin.

    thank mod...

    for download coding PC into BS2..
    i just power up my BS2?
    mean just connect 6V into Vin and also serial port only??
    got other connection?
  • Mike GreenMike Green Posts: 23,101
    edited 2011-02-28 09:39
    Yes, 6V into Vin and ground to Vss, then a standard serial port to the DB9 connector. If you are using a USB to serial adapter, remember that not all USB to serial adapters will work and you have to have the proper USB driver for your adapter installed on your PC. Most adapters that use the FTDI chip (like those from Parallax or FTDI) will work.

    It looks like your Interpreter chip (28 pin), is upside down in the socket. The white dot should be in the upper left corner.

    Yes, rotate 180 degrees. But...the chip might have been damaged when applying power in the incorrect position. Let's hope not.

    Did you put the resister Banks in the right way The Voltage detector and the 2n304 and the 2n3906 in the right place I have built these a few times and never had a problem getting them to work

    If your using a USB serial adapter it will not be COM1. COM1 is the DB9 serial port not found on most newer PC's (google DB9 to see what it looks like)
    '
    Don't force a COM port. Let the editor find the Stamp on COM ( ? ) with the USB to serial device.

    I agree with $WMc%. What you need to do is click in Preferences and set the COM port to Auto, which should take care of your problem.

    ok.... that time i using serial port.. not usb to serial port.... already take AUTO but still the same result....

    if i replace microchip... into PIC16C57-RC/P should can work also?

    How do I connect the BASIC Stamp to my computer for programming?

    You'll need a Basic Stamp 2 Interpreter chip, which is a PIC16C57 preprogrammed with Parallax's Basic Interpreter. You can buy it from Parallax (see link below) or I suggest you email Parallax tech support first - you may get it at reduced cost.

    The schematic for the OEM Basic Stamp (here) shows how to connect the microprocessor to a standard DB-9 serial connector. You connect that to a PC's serial port (or a compatible USB to RS232 Serial Adapter) to program the Stamp using the Stamp Editor, available from Parallax's Downloads webpage.

    You cannot just use a "PIC" as a replacement. It has to be the one from Parallax; it's special, because only it has the 'Interpreter' on/in it.

    Have you verified in your Device Manager that you have a good COM port? Is it COM1?

    As I suggested early on, I thought that you'd probably made some construction errors which turned out to be so. Have you verified the correct placement of every single component?

    i try with 2 type computer..
    1)my laptop..which is use usb
    2)lab computer,destop.... this PC port alredy tested OK..

    result same...NO BASIC STAMP FOUND

    when i swithch on.... my basic stamp hot.... this is normal?

    Hot -- definitely not normal.

    You pose many questions and answer few.

    my voltage regulator got yellow color on steel..... maybe it damage....

    new question:
    1)if i buy from website parallax...how min item i can buy?
    2)how long it can delivered.. i from ASIA.... i email distributor from ASIA.. they no replay yet

    It is not normal for the Stamp processor to get hot. The voltage regulator can get hot if you are using a high Vin like 12V or higher. As PJ Allen suggested, you have probably made some kind of construction error. Check for solder bridges, cold solder joints, etc.

    People have found that they get a "Stamp Not Found" error from a bad serial cable, a bad serial port, or a bad USB to RS232 Serial Adapter. Remember that some USB to Serial Adapters don't properly implement the DTR control signal which is necessary for programming. Some USB to Serial Adapters have a long latency (transit time) for the data and the Stamp or the Stamp Editor will time out and give a "Stamp Not Found" error. The default I/O drivers in Windows won't handle DTR properly. You have to use the Adapter manufacturer's driver.

    There is no minimum order from Parallax. Shipping is another matter. They have to charge you what it costs them to ship your order and there's a minimum shipping cost. Check with the Parallax sales department about shipping options to save costs.

    Nedd,

    I know this is frustrating, but we are trying to help.

    Can you take some more pictures, from a few different angles, of both the top and bottom (solder side) of the board?

    I think the Basic Stamp Interpreter chip (the PIC) was probably damaged when it was inserted incorrectly, so it probably needs to be replaced. Please note, as others have said, it must be a proper replacement from Parallax because it must be programmed with the BS2 interpreter code.

    I'm also concerned that you may have solder bridges or other issues such as incorrect component placement.

    Do you have access to a good multimeter that can measure DC voltage and resistance?

    C.W.

    Nedd,

    I don't see any obvious solder bridges, but please take a very close look yourself.

    Please verify the placement of the transistors and reset supervisor per the attached image.
