Is my stamp blown?

Posts: 46,084
Bought the BOE and earth measurements kits. Hooked it up to my Win
XP box using the supplied serial cable and plugged in the 9vdc
adapter. Installed the 1.33 editor software and tried to use the
Identify directive. It passed the echo and loopback tests but
doesn't show a board. Didn't pay much attention to that (after all,
the help system says I need an update so I say "sure update it" and
it says "Its already updated you goofball!" Not being able to
identify the board is no suprise).
I unplug the board, hook up the first EM setup (piezo speaker), plug
it back in and type in the single line program. Choose run and get
the error saying it can't find a stamp.
I futzed around with directives and went looking for the "default"
baud rate (9600 was chosen by default and it turns out thats the
right baud rate as far as I can tell). No luck.
I removed the stamp and re-seated it. No luck there either.
I broke out my multimeter and checked voltages. The 9vdc adapter is
putting out 14.8vdc! I checked the voltage between Vin and Vss and
got 11.6v. Between Vdd and Vss I got 3.2v. Off the regulator I get
14.8v and 6v on the legs.
I then plugged in a 9v battery and checked that. Vin is 8.2v and Vdd
is 3.2. Still no response from the editor software.
Did I get a duff board? Is my stamp most likely toast? Is there
anything else I can check to see if the stamp itself is ok?

I doubt you fried the stamp, 9V is actually in the middle of the allowed
voltage supply range. The reason it puts out more than the 9V battery is
that when it is under a load, like pull up/down resistors, driving something
with the outpust, etc., the voltage will then drop down.
I have had a similar problem with Windows 98, haven't tried it with my XP
system yet. I found that it was either an incorrect selection of the type of
Stamp in the editor setup, communications protocall, or even a bad serial
cable. Most of the time it turned out to be the settings in the editor
setup. Take a close look and make sure that you have selected the proper
Stamp type and that the extension on the filename is the correct one for the
type of stamp, in case you attempt to send an existing file to the stamp.
I hope this helps some.

I am quite certain your Stamp is okay. I believe it's the simple
matter of correct settings and that the 9-pin cable is firmly
connected.
Call up your Stamp Editor. Go to Edit/Pref.. Check for the correct
Com Port and Download Mode. Under "DIRECTIVE" select the Stamp you
intend to work with. (The type of Stamp you are using is always the
first line in any given progr. E.g. ' {$BS2e}

wondering if you were checking it on the right pins. If Vdd is really that
low the Stamp is never powering up.
First, remove the BS2 from the socket and set it aside. Disconnect / remove
anything else you have added or plugged in.
We are assuming you have a digital voltmeter.
Set the meter to continuity or ohms and check for a short between pins 4,
24, 23 and 21. You should only have continuity between pins 4 and 23.
Verify the AC adapter label says the output is somewhere around 9 volts DC.
Make absolutely sure it says DC.
Plug in the AC adapter but do not plug it into the BoE.
Set the meter to DC volts -- autorange or 20 volt scale is fine. Touch the
red (positive) lead to the tip of the AC adapter plug and touch the black
(negative) lead of the meter to the outside shell of the plug. The meter
should read probably 9-15 volts DC. If the meter shows a - (minus) symbol
the meter leads are reversed or the AC adapter plug is not polarized
correctly.
If this is OK plug the adapter into the BoE. The LED should come on
Hold the BoE component side up so the votage regulator is positioned with
the mounting bolt at the top and the pins at the bottom. Leave your meter
set to where it was before. Touch the black (negative) lead to the #2 /
center pin or mounting tab of the regulator and touch the red (positive)
lead of the meter to the #3 / rightmost pin on the regulator. You should
read about 4.9 to 5.1 volts DC. If not, the regulator may be defective.
If this works, connect the black lead of your meter to pin 4 of the BS2
socket. Connect the red lead of your meter to pin 21 of the BS2 socket. See
the Stamp manual if you don't know how the pins are numbered.
If this works, insert a short piece of bare wire into the Vss socket at the
top of the solderless breadboard and connect the black lead of your meter to
it. Insert a short piece of bare wire into the Vdd socket at the top of the
solderless breadboard and connect the red lead of your meter to it. The
meter should read about 4.9 to 5.1 volts DC.
If this works, chances are the BoE is OK and the issue may be with the
Stamp.

Go to directive

and delete the ports which you are not using.

You got that right, I was assuming the leftmost pin was common, not
center (So its been 14 years since I did anything with
electronics [noparse]:)[/noparse]. The voltages off the regulator are 14.8 and 5.0.
Guess this is fine.

With the stamp removed and checking just the stamp socket with no
power to the board I get:
4->24 is open
21->23 is 0.1 ohms
4-23 is 3 ohms
Voltages between these pins (stamp removed)
4->24 14.4
4->23 0
4->21 0.3
23->21 0.3
23->24 14.4
Voltages between these pins (stamp installed)
4->24 11.2
4->23 -0.1
4->21 3.0
23->21 3.0
23->24 11.8

Yep, 9v DC - this is the PS that came with the BOE kit - I did look
at the rating as soon as I saw 14.8vdc when I checked it with the
meter.

Checked, its 5.0 volts exactly.
I also just checked the two capacitors (marked 1000uF each). One is
showing 2500 uF on it (closest to edge of the BOE) while the other
is 1030ish. I'm guessing the 2500 uF one is a bit messed up?
p.s. Originally used my Ammeter for testing but brought home my
fluke #12 last night since it has capacitance too. My work deals
with simple electrical (volts,amp draw and continuity are about it)
so I've taken to using the combined ammeter/voltmeter for
convenience. Guess I'll "store" the #12 at home from now on.
As for the software settings:
I put in the BS2 and baud directives (BOE has the BS2, not the e or
x etc). I had already tried deleting com2 (PC only has one com port
attached).
I also took the BOE to work yesterday and tried it on a win 98
machine with the same result.
Guess I'll stop by Active Components on my way to work and pick up
another 1000uF cap! Should be warranty but I'd rather buy some parts
and fix it today than mail everything in and wait 12 weeks [noparse]:D[/noparse]
read the cap in circuit -- this is normal. From your readings, it sounds
like the AC adapter and regulator are fine.
I believe I misread the Stamp manual last night -- I looked at the schematic
this morning and found your voltage readings on the Stamp socket are
correct. The BoE regulator only powers the headers near the solderless
breadboard. The Stamp receives power between Vss (pin 4 & 23) and Vin (pin
24) and its onboard regulator powers the Stamp and the AppMod header.
If you are only seeing 3 volts between Stamp pins 4 & 21 and 23 & 21 it
sounds like the Stamp is bad -- this should read 5 volts if the regulator on
the Stamp is working properly.
I would remove the Stamp and make sure nothing is plugged into the AppMod
header and that there are no shorts on the back side of the board around the
Stamp socket or AppMod header. You could also use the meter to check for
shorts between the Vss header and each Stamp pin -- if one pin is shorted
and the Stamp is configured for output on that pin you would have a problem
as well.
If you don't find anything I would see about getting the Stamp replaced.

unusual problems, somewhat like you have described.

Mine came as Rodent described actually. There is nothing on the
board other than the rubber feet which are inside the dashed lines
as per instructions.
I'll pick up a second BOE kit on Friday (I want to play with multi-
stamp setups later anyway so what the hell). I'll be ULTRA careful
with this one. If it works I'll compare readings and see if anything
is different.
I'm thinking Rodent is right about the stamp's internal regulator.
Everything I see says Vdd is 5vdc and I'm only getting 3. Can't see
how I could have shorted the board but, you know how us damned n00bs
are [noparse]:D[/noparse]
mine to work at first either. On the old version of the Editor, you
needed to turn off other devices on the COM port (like I had my Palm
Hot Sync software active in the Systray). With the new version of
the editor, I had a similar problem. It would detect the Stamp, but
it wouldn't download programs. There was a setting I needed to
change on the Port setting, but I don't remember what it was or how I
did it. Parallax Tech Support probably knows what I am talking about
and can probably walk you through it. Parallax makes very high
quality products, so I am surprised that it is hardware related.
simple 1 line program.
it has to be at least 2 lines try this:
'{$stamp bs2/bs2sx/bs2e/bs2p-depending on the type of stamp you have}

determined his Stamp module had a bad voltage regulator.
