While the suburbs and rural areas surrounding Canada's largest city enjoy
very good digipeater service, the city of Toronto itself has lacked a
digipeater for over a year.
I am pleased to report that as of this morning digipeater VE3VWD is
providing service from the heart of Toronto. Located on a 34 story office
tower, the site provides an unobstructed view of the entire city.
Thanks go out to the Central Ontario Amateur Radio Club (C.O.A.R.C). A
special thanks to Bob, VE3ADJ for his invaluable assistance. Thanks also go
out to Bill, VA3QB for his enormous effort in making this happen.
73,

Need a past AFilter log for the date of 28 March 2003. email off sig if
you can provide this log file from AFilter with time stamp in the
header. This file will be about 100 Mb in size.
I have been collecting AFilter log files of the APRS internet stream
since Nov 2002 at two different sites for redundancy. Unfortunately, a
common point of failure occurred recently, so i am missing 28 March 03.
i will be reconcilling gaps between the two separate data streams, and
will offer final copies of the data using DSpace from MIT. DSpace is a
file sharing project using open source.
The AFilter logs will be utilized in an APRS project i will describe
later called Citizen Health Observer Program.
Respectfully submitted,

What is the favorite Basic Stamp processor these days?
I need one that has two serial ports and can handle 9600 baud I/O between
them. I looked up BASIC stamps and there are now so many to choose from.
This will be a basic building block for students to manipulate serial port
data. But some analog I/O woiuld also be nice.

BS1 will not work too well at that serial speed. 2400 was the fastest I
could get it to work reliably at.
BS2(x) should work.
I have no idea if any of them can support 2 serial ports.
I think Wes Johnston has done alot of work with the newer ones (I used to
use the BS1 but it was not fast enough for what I wanted.. now I just do C
direct with the parts)
If you want to stick with Basic, they now have compilers for the PIC...
much much better/faster then the stamps (which have to fetch their
instructions from a EEPROM).
http://www.melabs.com/products/pbc.htm
And my ICD2 even appears to support this in MPLAB!
But if your doing it for students, I'd do it in "C" because they can get a
job with that skill and list it on their resume. Basic is looked down upon
in the embedded world (like it or not, that is the way it is).
CCS "C" compiler will support 2 or more serial ports and has many lib's
available for it. While not totally ANSI compatible, it is a very easy C
compilier to learn for the PIC.

Also, HiTech is now making their PIC compilier available in a LITE version:

I am fond of the BX-24 from NetMedia.
It is pin compatible, but has built-in ADC, multi-tasking, floating point
arithmetic, and much more.
Far superior to the BS-2, IMHO.

Some do better than others with serial. The Atom for example, is supposed
to run serial port functions in the background (haven't used one, just read
their material). It is about $xx in onesies.
http://www.hvwtech.com/pages/products_view.asp?ProductID=379
The basic-x stamp has background serial too, but I haven't played with it.
I have done a lot with PIC processors and MELABS PICbasic pro. The code is
basic stamp compatible and compiles to run on things like a 16f84. I have
found that a 16f84 even at 20mhz was not able to keep up with 9600 baud data
without intercharacter gaps.... and a real basic stamp II would keep up. If
you want to run Pic Basic Pro, you can always use a PIC processor with a
hardware USART (like the 16f628). In circuit serial programming is easly
done, so the effect is just like working with a basic stamp, but a whole lot
cheaper ($x a chip vs $xx).
HVWTech.com has Stamp Stack II Kit for $xx which is a basic stamp kit and
the proto board for it is really slick, and for $xx is a great value. This
is what I used to catch GPS data and talk to the kenwood d700 to get smart
beaconing working on the kenwoods.
http://www.hvwtech.com/pages/products_view.asp?ProductID=12
With any of these processors, you can use the "real buffered serial port"
and also use any I/O pin as a hack for the 2nd serial port. I'd use the
"real" serial port for talking to a TNC, and the I/O hack port for listennig
to a GPS for example.

As long as we're on this subject, can someone suggest a good C development
environment for either the PIC or Atmel AVR? I do most of my stuff in C for
the Motorola HC08 series, and I like the Codewarrior IDE. I've downloaded
the Atmel development environment, and it looks nice, but it doesn't include
a C compiler. Is there anything good out there, preferably for free? And
preferably for Windows? I dislike software development on *nix platforms.
