Need Pbasic for Dummies! Help

T.O.-
Can you state your requirements in terms of a truth table? I'm
getting lost in the description. Sounds like the truth table may
need to include former switch settings, current switch settings,
current output states, desired new output states. Also, are the
inputs sampled and the outputs updated continuously, or at specific
intervals?
Cheer up, sounds like something the Stamp can do with just a few
lines of code.

Steve

For the life of me I can't seem to get the hang of writing a program
for the stamp! At first it appeared as though it would be simple to
control two relays with three switches right ! ( have very few hairs
left to pullout ). Was easier to build a logic circuit with a couple
of JK flip-flops, and a few AND gates yet would like to see just
what a stamp can do to save parts and a lot of wiring. 20 plus years
ago enjoyed playing around with the old basic on a VIC 20 now trying
to relearn all this Greek or Latin ( Pbasic ) What I would like to do
is simply toggle the state of two outputs depending on, the on or off
state of the same 2 outputs and 3 inputs ( switches ), with the
following rules.
Must start with outputs =0
Output X and Y can never be toggled on at the same time
Output X can never go on if switch 1 is already on, but can toggle
X on if first was off
Same applies to to output Y and switch 2
Switch 3 toggles off X or Y first if X or Y =on
or allow X on only if switch 3 is on
or allow Y on only if switch 1 is on
Can anyone help?
P.S.
Will purchase the first Pbasic ( Greek ) for Dummies!
Looking for software that will convert a logic circuit to stamp
program ( Un-Greek-tified ) or similar.
Thanks T.O.
First OUTPUT X AND Y = 0
At startup if switch1 is on and switch2 is on then Output X and Output Y
cannot be turned on from switch1 and switch2 because there aready on
therefore switch3 would turn on Output X because it initialized in the
output x = 0 state but if switch1 is on at the same time switch3 is on that
would indicate output X and output Y to be on at the same time
basically stating that
Output x = 0
Output y = 0
if switch1 = 1 and switch2 = 1 and switch3 = 1 then
How is this statement true if they cannot be on at the same time?
Switch 3 toggles off X or Y first if X or Y =on
or allow X on only if switch 3 is on
or allow Y on only if switch 1 is on

hairs I had on top are now gone and I'm still unable program my stamp
II to work the way I'd like and replace my logic circuit.
The present logic circuit I've created controls a 3 level elevator.
The top and bottom levels each have two switches with two additional
switch in the elevator wired in series ( see below ) with first and
third level input. All are normally closed type switches. The center
floor has 2 switches wired in series connected to a third input. The
two outputs control a pair of opt-triac that provide up down action.
On start-up one of any single (b.) switch will normally be open
depending on location of elevator. Both outputs must be off on power
up. F3(b.) and F1(b.) prohibits elevator from going beyond that
level. Please not, the (a) switches toggle its correspond outputs on
as long as both outputs are off , and what other (b) switch is open
determines what direction (output to turn on ). Once elevator is in
motion the (b.) switch it was stopped on automatically closes before
the next floor allowing the (b) switch to open and toggles elevator
to stop if output is on. Please note, based on what floor elevator is
on, Y input is the only input that can allow one or the other outputs
to go on but never at the same time.
My logic circuit allows the following:
U=0 and D=0 ` when first turned on
If X input =1 and Y =1 and elevator is stopped outputs =0, elevator
is at Z (Z=0), with input Z open, X or Y must not allow Doutput on
ever.
If X input =1 and Y=0 and Z=1, elevator is at Y (level 2). Note
with Y input open X(a) or Z(a) can still page elevator when one or
the other opens then closes starting elevator in that direction. When
that input again opens, elevator stops on that floor.
Paging Elevator
with input Y open, X (a) or Z (a)inputs when one or the other is
toggled allow elevator back on, X input toggled for Up, Z input
toggled for Down. When elevator reaches the corresponding (b) switch
opens turning output off.
No output can ever be on at same time.
Also note once elevator is toggled in the correct direction and in
motion that level it was on closes leaving all inputs closed until
the next input is opened at the level it reaches.

when i was programming the Allen Bradley PLC at ITT Tech. it was fun if you
ever played with one of those (Ladder Logic). However Things have changed
since the STAMP. its no longer necessary to have switches in series
anymore. your a logic thinker and if you think you have no hair now just
wait until you read the program. first of all the BS2 has 16 I/O lines and
we should utilize this! the elevator system i designed has 9 inputs and 2
outputs. read the program and notes in the program for details. hope its
PBasic Legible !! email if you need assistance. and to those you are
experts in Pbasic you probably know of a way to shrink my variables but
this is how i understand the program. Thanks and good luck

This will be a big help to me now trying to learn this pbasic
language. To save chips and wiring with my first logic circuit, my
goal, became a challenge to cut down on switches and wiring. ( 28 IC
chips with 9 inputs 2 outputs). My present logic circuit consists of
a total of only 5 IC with only 3 inputs 2 outputs needed. I still
hope someday to incorporate a smaller circuit with the least amount
switches and wiring. Any additional input as always will be greatly
appreciated .
