Basic Stamp/Microcontroller accessory ideas
Archiver
Posts: 46,084
Hello,
I am planning on making a series of small, simple, and inexpensive
support chips for BASIC Stamp and other microcontrollers. I have a
few ideas already, but I would like to ask for a few ideas that
people think would be useful. The first of the chips will have a
max of 6 IO lines, and be priced probably between $3 and $6 each.
Eventually I'll move to larger chips with more functionality, and
eventually plan to make a fully-programmable coprocessor. I'd like
to know what kind of chips people would want, and how many of each
people would want so I know how many chips to order.
Thanks!

Nice offer. We are currently discussing the implementation of software for
our stamp expansion board SYNOP.
(http://www.boselectro.nl/synop.html)
This board features a Stamp and eleven SX18. These are daisychained linked
AND share an I2C bus.
Ten of the eleven SX18 are I/O coprocessors. In their most basic form they
should allow the stamp to
control the I/O pins, nothing more (PCF8574 emulation). For more advanced
tasks special programmed
SX18 could be used (i.e PAK-like devices for an I2C bus).

Yes, I eventually plan to make a small addon board that will be a
fully functional sub-processor in itself. It should be able to
control as many as 1024 chips using my ChainLNCS linear network
system. There are two things in my way though. First of all, I
can't afford the cost to manufacture PCB's for ANY component (the
minimum price is around $500!!). Second, I had a bit of a chemical
spill (coca cola) on my desk that took out my PicBasic disk! grr...
Well anywyas I'm coming along quite well with assembly. If anyone
could help me replace my PicBasic I'd gladly send some samples of my
chips when I start to manufacture them. I still have to learn
PicBasic as I didn't even get the damn program isntalled before I
lost it :-/
One last note. I am NOT trying to go in direct competition with Al
Williams. I respect his business and his very good products. In
fact, i'd be more than willing to cooperate. My chips will mostly
be based on expandability. My ChainLNCS network system will allow
up to 255 expansion chips to be controlled by only one BASIC Stamp
pin!! The further down the chain, however, the longer it will take
to get the message. The initial devices will most likely have 2
pins used for the network (one input, one output) and 3 general IO.
I will do my best to provide as much functionality as possible. I
plan to have the following commands on the chip:
Serout (1,2,3)
Serin (1,2,3)
Shiftout(1)
Shiftin (1)
High (1,2,3)
Low (1,2,3)
Input (1,2,3)
The numbers after the pin indicate The networkable chips will not
have functions like servo control, etc. because commands that need
extended amounts of time to execute could block the flow of data on
a chip further down the line. However, the chip described above
will be able to send the serial commands necessary to control the
more complex chips.
Thanks for your interest! If you would like to put some chips on
reserve, just ask. Keep in mind I probably won't have them in
production for a couple of weeks though, because my programmer unit
hasn't arrived yet and the homemade one I built only does the 16c84
and 16f84.

The PAKs do that to some extent. For example, a PAK-VIII generates 8 pulse
streams while the Stamp is free to continue doing it wants to do. The
PAK-VII measures 8 streams; PAK-V generates 8 channels of PWM, etc.
Because of the PAK protocol, a PAK-III or IV will let you issue a command to
the coprocessor, go do something else, and only read the result when you are
ready -- sort of multitasking.

* Expand your Stamp I/O
http://www.al-williams.com/awce/pak3.htm
We don't have any distributors in Germany as of today. However, Kanda now
carries the PAKs (they are in the UK). Selectron (France) has stocked some
of our parts, but not all of them and I don't know enough French to direct
you to their site. Of course, we ship worldwide and now we use Global
Priority Mail, so the shipping is even faster than the Air Small Packet we
were using (at least, the post office tells us it is). You can order
securely from our Web site.
If you'd rather get them in the UK, go to www.kanda.com and pick online
shop. Then pick Tool Box (not chips - don't ask why). You'll find all the
PAKs up to PAK-VIII on the first 2 pages.
