Nuts & Volts October ISD chip project
I was very glad to see the ISD article in October's issue of Nuts and Volts.
I've been trying to find that solution for quite awhile. One thing the
article mentioned is that is was possible to use fewer stamp pins by using
shift registers? The author said he would show how if he got enough
requests. Since I know he is on this list, I would love to request this
example!!!!!!! I have a project that has been on the back-burner for a
while now, because it needs to use the ISD chip heavily, but will also need
to read several switches and controls several solenoids, so I need to save
the stamp's pins for other things, and can't dedicate them to the ISD chip.
Schematic/parts/program, would be VERY helpful!! (I also sent the request
to Nuts and Volts)
PLEASE HELP!!!!!
Thanks in advance,
Shawn

Use 1 Stamp pin as the clock to shift the register to your required bit
settings: 1 = On, 0 = Off. An 8-bit register will give you either 8 pins
directly, or 2**8 = 256 different combinations with some AND/OR gates.

Hi Shawn -
You are quite correct, and here is the last time Jon spoke about it:

If he doesn't respond here to your inquiry, I doubt he'd mind if you sent
him a short note at the email address noted.
Regards,
Bruce Bates

Okay, okay. But I've written a bunch of shift register stuff for my articles
-- it should be too tough to figure out.... Anyway, I'm working on a 1-pin
solution by putting an SX chip between the Stamp and ISD, sort of a
"backpack" for the ISD.
I'm sure that I'll have a bit of time over the holidays and I'll squeeze in a
bit of time for the shift-register to ISD project. Right now I'm very
excited about the new BS2-SX Plus and am spending all my time with it.

Just finished such a project with twenty or more each inputs and outputs
It's for a model railroad- schematics & code on my web site:
