Stamp2 Novice Help Needed

Posts: 46,084
Hi!
I just fired up my Basic Stamp II on a Super Carrier board and
connected it to my PC. I am running example programs on Windows98,
using the Stamp2 program for Windows and get the following error:
Could not open com port - reason unknown.
Please provide me with suggestions who to resolve this error.
Thanks a lot!!

Comments
check status under Control Panel - System - Device Manager - LPT and Com
ports. Make sure there are no IRQ conflicts if there are there will be a
yellow question mark.
Next ensure you are using the right plug on your computer. Mine has no
labels on com1 or 2 so I had to test to find the right one.
Good luck

Do you get the same can not open message if you try to run Hyperterminal
from the accessories folder. Do you have the StampW program optioned for the
correct com port or auto detect. I had similar problems and it was that the
com port was not working. My stamp and its' board was just fine.
Good luck,

I am having problems with my PC also. I have been using the com port for other
things, like my Palm Pilot and another microcontroller with no problems so I
know the COM port works. When I try to run stampw.exe or the DOS stamp program
I get the error message:
BASIC Stamp II not responding
1. Check serial cable connection.
2. Check power supply.
Which does not make sense because when I use the same cable on my laptop then I
get communications with the StampII. I have checked the settings on both the
laptop and PC and the COM ports are set up exactly the same. And there are no
other programs using the COM port on my PC. I am really frustrated with this.
Maybe someone else has had this problem.

Disable Hot Sync for the palm.
There is your trouble. It looks like palm pilot has your serial port tied
up. What happens when you use the other serial port? Are you running
windows98? If so, there ae documented serial port problems with some mother
boards. I know. been there, done that... Would really like to know what OS
you are using.

If memory serves me correctly this might be an indication that your BS2 IC
might be installed upside down in chip carrier.
Easy to do if you're reading step 1) on p199 of manual 1.9.
It says that the largest chip on the BS2 IC should be furthest from the
reset button.
On mine the largest chip actually had to be _closest_ to the reset button.
The carrier board layout as pictured on p199 of manual 1.9 is quite a bit
different from the one I got.
Hope this helps, careful taking out the BS2 IC, I had a heck of a time
getting mine out.

My COM port is setup as:
9600 Baud
8 Data bits
1 Sop Bits
Xon/Xoff Flow Control
I have tried Hardware and none for Flow Control but hey don't work either.
I am sure it is something so simple that when I figure it out I will kick
myself for not spotting it earlier.

Thanks for the suggestion, but I have Hot Sync set up so it only runs when the
Palm
Desktop is running. At least I think it is because I don't see the Hot Sync
icon at
the bottom of the screen. I have had that problem before.
Thanks,

I agree about the carrier board, I almost ruined the Stamp when inserting and
removing it from the carrier board but I am not using the carrier board,
instead I am using my own board and I know I have everythng hooked up properly
because if I take the programming cable from my desktop and put it on my laptop
then everything works. So the problem is with my desktop machine. I am using
Windows 95 if that makes a difference but the Stamp is the only thing I have
had problems with on the Com port.
Thanks.

my
palm application was tying up the port. Try turning off your palm application
in
the Windows SYSTEM TRAY.

Hi everyone,
I am having problems with my PC also. I have been using the com port for other
things, like my Palm Pilot and another microcontroller with no problems so I
know the COM port works. When I try to run stampw.exe or the DOS stamp program
I get the error message:
BASIC Stamp II not responding
1. Check serial cable connection.
2. Check power supply.
Which does not make sense because when I use the same cable on my laptop then I

I'm kind of new to this myself but you could use
high (pin) the pin you want high
pause 3000 3 minute pause
low (pin)
however if you want the stamp to be doing other
things while the pin is low, this wont work so you'll
have to come up with maybe a 555 timer.
Let me know how ya make out.

My last message was incorrect the pause statement is only good
for 65535 ms. I think the 555 timer would be the way to go,
that way your hardware can be busy during the 3 minutes.

Here is a simple way to do it :
high 1
for M=1 to 3 ' 3 times...
pause 60000 ' ... 60 seconds
next
low 1
But maybe you want to hold that pin high while the rest of the program is
running... then it's a little bit more complicated.
I would use an external timer connected to an input of the BS2, so you can
control the state of the timer in your program, and switch the output
according the timer's state. You'll also need to trigger the timer with
another BS2 output.
Another way to do that is the Pocket Watch B from Solution Cubed. This
module is a real-time clock, with programable alarms. You can read the time,
and set an alarm 3 minutes later to switch your BS2 output. You can also
program a 3 minutes one shot alarm.
I used this module in a central heating system control, it's very useful for
time-related applications.
I'm a new stamp user too, but I hope this can help you.
Best regards,
