Help! BS2 New user!
Archiver
Posts: 46,084
I have been a BS1 user for years. I wanted to do a project with a BS2.
I cannot get the darn thing to work!
I did a very simple program of HIGH 7.
Pin 7 becomes high but I get this weird pulse every 2.5 seconds on the pin. It
then goes low for a blip. This is fustrating as heck! I only have the serial
port and power connected. I see this on all the pins. I can see it with a volt
meter and if I have an LED on the pin.
I am using a BS2 Rev E and the DOS BS2 program. Anythoughts????
This is another problem. I cannot get the 1.33 windows editor to recognise the
BS2. The DOS version works and so does the 1.04 version...odd if you ask me.
Thanks!
Steve

on my system when i fed Vin from the high leg of my 7805. I had it
set up where I'd switch off the +5 supply to all my chips but the 9v
was still going to the stamp. LEDs off my PCF8574 would actually be
dimly lit and pulse as you describe. I figured out that I was
actually powering everything through the stamp pins.
I switched Vin over to 5v so it'd be turned off at the same time as
the rest of the breadboard and the pulsing disappeared. My
temperature sensors were jumping around a lot less too.

sleep to conserve power. However, that makes it watchdog out every 2.5S
and then it realizes it should be asleep so it goes to sleep again.
Here's the trick:
HIGH 7
Iamdone:
Goto Iamdone

every 2.5 seconds while its asleep. Put a loop with a pause in it after the
high statement to keep the Stamp occupied:
DEBUG "Hello World"
HIGH 7
Loop:
PAUSE 500
GOTO Loop

Scott Edwards book "Programming and Customizing the Basic Stamp
Computer" has a blurb in chapter 5 that suggests the problem has to
do with serial-port buffering. I had the problem you describe on an
old Toshiba laptop and found that the following solved it:
1. From the Windows Start menu, select "Settings" - "Control Panel"
2. Double-click the "System" icon and select the "Device Manager" tab.
3. Click "Ports", the double-click the com port to which your stamp
is connected.
4. Select the "Port Settings" tab and click the "Advanced" button.
5. Uncheck the box labeled "Use FIFO Buffers"
6. Click the OK buttons on all the windows opened above.
(The above was copied verbatim from Scott Edwards book)
