newbie question.. about basic stamp 2 OEM
nedd
Posts: 19
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?
but 'no BASIC stamp found'..

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.
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:

:cool:
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...
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?
but the result still
unfortunately... my university doen't have ppl work on BS2.. some can giv other idea to connect BS2 with PC...?
u mean..
.
should rotate....rite?
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.
if i replace microchip... into PIC16C57-RC/P should can work also?
How do I connect the BASIC Stamp to my computer for programming?

feeling weird...i try many times... same result.... i check my microchip not same with the module.... but distributors give to me.. should no effect if microchip not same?

yup...that PIC what i get from shop with BS2 OEM module kits...

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?
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?
You pose many questions and answer few.
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
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.
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?

some of pic....
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.
