With the exception of the event code not working (we are pushing the=20=20
end of May here folks), I haven't had any problems with the OOPic. I=20=20
have a Mark-III and an OObot-40-III board from Oricomtech. I have=20=20
never had any trouble interfacing simple I/O (switches and LEDs).

What seems to be the problem?

Hi Dave - well it's too simple. All I'm trying to do is to emulate a simple
push button on/off switch. I have an oLED object and an oSwitch object and
I'm using a C.1.X chip and the OOPic 6 compiler. All I have is a simple LED
and a board-mount micro-switch that I bought from the local Tandy store
(normally off). My code works perfectly and I can turn on the LED in code
but the moment I introduce oSwitch into the code the LED comes on and stays
on and the state off the switch seems to be ignored. My code is an exact
copy of the code on the website - and everything seems to be wired up OK. It
just doesn't work.

Dim Fred As New oSwitch
Dim Bob As New oLED

Sub Main()
Bob.IOLine = 8
Fred.IOLine = 9
Do
If Fred.IsOn Then
Bob.TurnOnBright
Else
Bob.TurnOnDim
EndIf
Loop

End Sub

Let's assume the code works and that, as far as the OOPic is
concerned, the input is ON. Check with pin voltage with a voltmeter
while toggling between on and off.

I wouldn't use the schematic shown for oSwitch. I am allergic to
solid connections to either +5V or ground. If I make the mistake of
defining the pin as an output, I will short it through the switch and
probably destroy the chip.

So, I would first add
OOPic.PullUp = cvOn as the second executable statement.

I would ALWAYS add
OOPic.Delay = 5000 as the first... (use 500 for V5 of the IDE)

Then I would connect a 330 ohm resistor between the pin and the switch
(normally open) and connect the other side of the switch to ground.
This way the resistor limits the pin current regardless of how I
define it.

Then, failing to get it to work with the new objects, I would rewrite
it as:

Dim LED as new oDIO1
Dim Switch as new oDIO1

sub main()

OOPic.Delay = 5000 ' 5 second startup delay
OOPic.PullUp = cvOn ' pull up resistors on IOLines 8..15

LED.IOLine = 8
LED.Direction = cvOutput

Switch.IOLine = 9
Switch.Direction = cvInput

Do
LED = Switch
loop

end sub

Of course, I have blown off the dimming capability and inverted the
sense of LED. I am assuming the LED is connected through a resistor
to +5V. So, the LED IOLine needs to go to 0 to turn on the LED and
the switch input should go to 0 when the switch is turned on (pulls
the pin to ground).

Now that the simple things work, try the new objects. Later, try the
oWire object and get rid of that Do-Loop.

Add to the declarations
Dim Wire as new oWire1

Then add to the code
Wire.Input.Link(Switch)
Wire.Output.Link(LED)
Wire.Operate=cvTrue

You may need to tweak the links for the new objects, I am not in a
position to check this at the moment.

Mike I don't see anything wrong with your code. Can you tell me how you have your switch wired and connected to your OOPIC. Make sure you have the resistor in line with your input pin to protect the inards of the pin circuitry. Be sure you also have a ground and 5 volts hooked to either side of your SPDT switch. Then is basically an EVENT style program, and EVENT programs are notoriously uncooperative in the Ver 6 compiler. I've loaded the attached code into an 'R' board ver 2.x+ using ver 6 compiler and changed the IOlines - works great!

Hi Dave and everyone that replied (I will get around to replying to
you all soon). I created a folder called Maze_bot and placed a photo
of the project there. I did make one mistake though - it's a B.1.0
chip (not the C.1.1+). The red diode just turns on and stays on
(flickering). The green led is just a test to satisfy me that the
switch works. I've taken note of some of the great code snippets sent
and I'll get around to testing them on the weekend. Thanks to all.
BTW the way, the grrr was pointed at my own inability to figure it
out - not at the OOPic (which I think is great).

OK, there's a potential glitch. The oLED object was introduced in B.1
and has issues with a level of 15 until C.1. This is well noted in
the documentation. Also, I can't find documentation for the
LED.TurnOnBright method (I'm assuming it is a method) but I'll bet it
sets the value to MAX which is (wait for it...) 15.

What I don't know is why you want a dimmable LED that requires 4 of
your precious 86 object bytes when you can use an oDIO1 that uses just
1 object byte. Then again, maybe the application requires it...

I know I am the only guy on the planet that feels this way but I still
prefer the simple and well understood objects. I also prefer the old
V5 IDE/compiler. I sort of like the idea that events will work.

It is very important that you note the IDE version and device revision
when you post inquiries. At this point the permutations are getting a
little large.

Sorry - just realized how rude I've been not replying. I don't mean
to be. I've just decided to go off-line until I know enough to post
something intelligent. I'm teaching myself digital logic from a book
written in the 70's (The preface said that at the time of writing
there was only 35,000 computers in the US- LOL). Sounds dumb but it
looks like a great starting point. The simple switch thing in my last
post made me realise just how much I don't know. I got to the page in
Dennis' book that talked about linking the output from logic gates
and just drew a blank. This book has a "start from the beginning"
approach. Really good. Assumes the learner has no previos knowledge
and is very well written. I Learned about truth tables today and
binary logic theorems and simplifying circuits mathematically. Also
about simplifying multi-variable tables using a thing called
reflected grey code and Venn diagrams. Also learned about DeMorgan's
Theorem today. Really interesting. If anyone's interested I can post
the ISBN of the book. It's probably out of print by now LOL.

www.alibris.com has a LOT of used books. So just post the title and
author with or without the ISBN.

My fist book was "Logic Design with Integrated Circuits by Wickes
published in 1968 - I bought it in early '69. At that time RTL logic
was king of the heap and DTL was just coming into play. What an
exciting time!

My book is called Digital Logic and Computer Operations by Baron and
Piccirilli published 1968 McGraw Hill. It's quite good. Is a little
confusing in some parts because some of the diagrams have labels on them
that aren't referred to in the text i.e. It has a block schematic of a
single pulse generator (like an oOneShot ?) with two terminals marked F and
G and makes now reference as to what that means. In one diagram the G
terminal is connected to the toggle switch of a set/reset type flip-flop but
in another diagram it had the F terminal connected. Do you know what they
mean?

It would be hard to say without some context - like a scanned image of
the circuit. All books of that era predate any standards in nomenclature.

>From your description, it seems that in one case the flop is
triggering the one shot and, in the other, the one shot is toggling to
flop. Or perhaps it is toggling at the beginning of the interval in
one case and at the end of the interval in the other. Perhaps F & G
are better termed Q and Q'? Hard to say without more context.

www.alibris.com has a copy of the book for $2.77 and several more at
increasing prices.
