Newbie - Stamp2 - VB via Debug
Please forgive what I hope is a very silly question.
I have a BS2 connection through a serial port to COM 1.
Using Stamp2.exe, I have a program reading input from an LDR circuit every 2
seconds and outputing to DEBUG - works fine.
I have the Serial Port Complete code for the template application amended
with RThreshold = 1 to ensure that OnComm fires. Port is set to COM 1 and
Baud is 9600,8,n,1. However, OnComm never fires!
I can make OnComm fire if I set 'MSComm1.Output="BLAH"' and then open the
'Change Node Set Up' window and click OK, with the BLAH being echoed.
Obviously, I can't have Stamp2.exe and the VB App running at the same time,
how can I check that the program is running on the Stamp, or find out what
is going on? I'm not an EE and don't have LEDs and stuff available.
Any pointers gratefully received.
Duncan

I dont know the solution to the fireing of the event, but there is a
VERY usefull tool you can use to monitor the serial data that goes
through any port.
Go to http://www.win-tech.com/html/listen.htm and download the
listen32 version. You can monitor the port when the Stamp is running
and see that you are getting the right incoming data and make sure
that it is correct.
As for the VB side of things, I know you propably done everything I
am going to mention, but here's just a recap of the mscomm
functionality, just in case .... (out of the VB Help)

Also make sure that you opened the port (mscomm1.portopen = true) and
when your code ends, make sure you close the port again. Otherwise
the port sometimes end up being "unavailable" and you have to restart
the machine or reset the port (I think you can reset the port in
win2000 but not in prev OS's)
Hope this helped
Cheers

I'll give it a try.

I think that it may be already, but I'll check anyway.

Any other ideas? A silly question, if I load a program through
stamp2.exe and then shut that application down, the loaded program
does stay running, doesn't it? What about after a power down?
Thanks,
