Basic Stamp newbie intro and questions

Archiver

Hi everybody,

I am currently working on a project where it appears that a Basic
Stamp is the best option for part of an interface. What I need to do
is turn 16 contact-closure inputs into an 8-bit BCD output. I have a
couple of questions about it.

1) As a newbie to Basic Stamps, I need a good place to start in
learning how they all work. I have already looked at the FAQ on the
AWC site. Is there a 'Basic Stamp Bible'-type book that is good for
beginners, containing sample code, circuit designs, etc. I have some
electronics background, so I'm looking more for applications info
than theory.

2) From preliminary research, it looks like the BS2p40 is the only
unit that has the I/O that I would need. All of the carrier boards
that Parallax makes are designed for the 24-pin package. You need an
adapter for the 40-pin package. Does anyone make a 40-pin carrier
board with a regulated power supply, headers, etc.?

I'm sure things will change as I get farther into this project, so
expect more questions.

Thanks,

Hi Doug Dixon;

A source for information about the Basic Stamp is the www.parallaxinc.com
web site in their download
sections. At the download sites are a lot of projects, code examples, manuals,
and other misc. docs. As for an
experimenter board I would get their StampWorks Full Kit, BS2p24 or BS2p40,
BS2p24 board (for 1-wire devices), and
BS2p24 to BS2p40 Adapter board. With 1-wire devices you might find that a
BS2p24 has enough I/O pins for the
application you are wishing to build. Check the information about 1-wire and
see if this fits your needs with a
BS2p24. I am fairly new to the stamp also and find most of the information I
need from this forum and the
Parallax web site.

Have Fun !!

1) If you look on the Parallax site, you'll see there are several books
out including mine (http://www.al-williams.com/awce/sbook.htm) and one
by Scott Edwards, and some others too.

2) An easy way to go is use an APP-II
(http://www.al-williams.com/awce/app2.htm). This works with a solderless
breadboard and will work well with a BS2P40. It does use the chip's own
regulator, although it is easy enough to build a 78L05 circuit on your
breadboard if you prefer.

Good luck!

Not to put you off of the Stamp, but you might be able to accomplish
what you need to do simply with some diode steering. "Off load the
task" as it were.
