im reading a signal either (1 or 0) from an input pin. and I want to change

controlled by the program. I had try to use the BUTTON command. but some
how the output pin does not change state. So can any body can help me on

Perhaps if you posted some code, or were a bit clearer on your goals
someone can give you more help. Is your active state on the input high or
Low? Do you want the output to match the state of the input? How is the
output pin controlled by your program?
it to do something based on the state of that pin? If I do something
like this:

> Stamp? Does anyone have any hardware recommendations for this kind of

If you use some Stamp pins for clock, strobe, and data you can use cascaded
serial-parallel shift registers to add lots of digital inputs and outputs
to your system. The biggest limitation will be the amount of memory you
have to store the data being shifted in and out. Another limitation is you
cannot use a single shift register pin for both input and output.
To keep your system stable be sure to choose logic parts that have a strobe
input that either transfers the data shifted into the part to the output
drivers (for output shift registers) or latches the state of the parallel
inputs (for input shift registers.
Tim
I agree partially with Tim that storage capacity is the biggest limiting
factor. If you however add a
serial ram chip of 8kbytes (using addiotional pins for TX/RX) you can store
8192 bytes for a total
of 8x8192=65536 expanded I/O. So storage is not really the biggest liniting
factor.
Also if you use I2C rather than shiftregisters, pins can be used for inputs
and outputs.
The biggest linitation is speed of operation. Any application requires some
minimal speed of operartion. Normally
output pins are set depending on some inputs and some calculations. More
inputs -> longer processing ->
lower speed of operation (longer main loop cycle time). You can somewhat
precalculate the speed of operation by looking
at the required inputs you need, the required outputs and the processing.
and then decide wether or not the stamp
is the appropiate controller to use for your application.
As far as hardware is concerned, I can only reference to our own design
(http://www.boselectro.nl/synop.html) that
offers 80 digital I/O on a single board. I do recall however, if I am not
mistaken, a post from someone which had
a system offering 1024 I/O.

explains it in my project is a pdf file. Like they are all pdf files. The
last half of the sentence explaining is currupt there is all white space
(laughing out loud). I understand that you can address all the pins like
in 4, 8 and 16 groups. From 0-3 if four bits, and so on. But whats the 15
stuff? I know there is something about a direction and something else?
DAC:
dirb = 15
outb = n
return
controlled by the Dirs register -- 16 bits, one bit per pin. If the
associated bit in Dirs is one, the pin will be an output; if zero (default
after reset) the pin is an input.
Dirs can be broken down into groups:
Dirs
DirH, DirL
DirD, DirC, DirB, DirA
Dir15 ... Dir0
In your example, DirB is being set to 15 which is %1111 in binary -- so all
of the pins in this group (pins 4 .. 7) are being set to outputs, then the
value of n is being placed on those outputs.
This stuff is covered pretty thoroughly in the manual.

dirb = 15
Is setting p4, p5, p6 and p7 high???
From what I do understand the "out" word is used to set outputs I thought
I would do:
outb = 15
To set p4, p5, p6 and p7 high. Thats why I'm assigning it to a variable
thats a nibble. Well you didn't know that but still... Now I'm really
confused. I don't understand the word "dir" but it says it has something
to do with "I/O pin direction control" here in the book so I'm making the
assumption it has something to do with controlling the direction of
something...?

dir - Sets the I/O DIRection weather or not it is an INPUT or an OUTPUT...
I "think" if I remember correctly the analogy that I used to get it
straight
in my head was that a "1" closely resembles an "I" for INPUT where
a "0" represents an "O" for Output. Set these bits so that they
correspond to how you will utilize the I/O pin, be it an Input or
Output.
Note: You can change this at any time in the program if the pin is
required
to change it's I/O status.
out - Sets the OUTPUT State to a HIGH or LOW and has no effect on a pin
set as an INPUT.
-Beau Schwabe
dira = %1111
Will set p0-p3 as outputs, and they will be low until you make them high.
From what I got in the v2 manual they are all low when you first make
them outputs.
outa = %1111
Will make all of the outputs go high.
when you do 'OUTB = %1111', the Stamp first converts
the pins to output, then sets them high, in one action.
It doesn't care if they had been set as inputs before.

register for pins 4 - 7; changing the contents of OUTB only affects those
pins in that group that are set to outputs (setting is in DIRB; 1 = output, 0
= input).
You are confusing OUTB with the OUTPUT command, which only works with single
pins.

I tend to only work with the OUTPUT, HIGH, and LOW command, so you
are correct.
HIGH 13
PAUSE 100
LOW 13
will make pin 13 an output, put a high on it, wait
100 mS, then put a low on it. It will be left as an
output.

Thank you
Edson
or out?
If you're looking for simple digital input expansion a couple of really
simple parts to work with are the 74x165 (inputs) and its complement,
the 74x595. They are both serial/parallel devices and need just three
pins each -- and you can share the clock line so with just five Stamp
pins you can get a bunch of extra I/O space.
Our StampWorks book has experiments with both chips and I wrote a Nuts &
Volts column a couple years ago that shows how to tie them together.
Everything is available for download (as a PDF) from our web site.

If you want to expand only outputs, use a 74HC595. The Parallax web sight has
good documentation how to hook them up and example code.
If you need to expand inputs and outputs, I recommend a 74LS299. This one IC
can act as both expanded input and output.
The IC expands input by recieveing parallel data, which is then fed to the
stamp via the SHIFTIN command. The IC can also expand output by recieving data
from the stamp via the SHIFTOUT command and send it to parallel output ports.
SHIFTIN EXAMPLE

SHIFTOUT EXAMPLE FROM PARALLAX
' Program: 74HC595.BS2 (Demonstrate 74HC595 shift register with Shiftout)
' This program demonstrates the use of the 74HC595 shift register as an
' 8-bit output port accessed via the Shiftout instruction. The '595
' requires a minimum of three inputs: data, shift clock, and latch
' clock. Shiftout automatically handles the data and shift clock,
' presenting data bits one at a time on the data pin, then pulsing the
' clock to shift them into the '595's shift register. An additional
' step--pulsing the latch-clock input--is required to move the shifted
' bits in parallel onto the output pins of the '595.
' Note that this application does not control the output-enable or
' reset lines of the '595. This means that before the Stamp first
' sends data to the '595, the '595's output latches are turned on and
' may contain random data. In critical applications, you may want to
' hold output-enable high (disabled) until the Stamp can take control.
DataP con 0 ' Data pin to 74HC595.
Clock con 1 ' Shift clock to '595.
Latch con 2 ' Moves data from shift register to output latch.
counter var byte ' Counter for demo program.
' The loop below moves the 8-bit value of 'counter' onto the output
' lines of the '595, pauses, then increments counter and repeats.
' The data is shifted msb first so that the most-significant bit is
' shifted to the end of the shift register, pin QH, and the least-
' significant bit is shifted to QA. Changing 'msbfirst' to 'lsbfirst'
' causes the data to appear backwards on the outputs of the '595.
' Note that the number of bits is _not_ specified after the variable
' in the instruction, since it's eight, the default.
Again:
Shiftout DataP,Clock,msbfirst,[noparse][[/noparse]counter] ' Send the bits.
pulsout Latch,1 ' Transfer to outputs.
pause 50 ' Wait briefly.
counter = counter+1 ' Increment counter.
goto Again ' Do it again.

Clock and data can be shared. Latch lines must be separate. I am running
three daisy-chained 595s with 5 lines.

Correction - I'm using 3 lines, not 5.
