Hi Chris
I have given it a try, and nothing happens,
I get no errors on programming etc, but nothing.
I have changed the control pins around as you have used a different orientation, wonder why this was? any reason,
All looks fine as far as I can see.
?????
Cheers
Dave.

Not sure what you mean by a change in pin orientation? Could you explain what it was you neded to change.Originally Posted by g7jiq

Hi Chris
My pin out was
InputTrigger var GPIO.0 ' Input normally HIGH, goes LOW to Trigger
Output0 var GPIO.1 ' Normally high, goes low when triggered
Output1 var GPIO.2 ' Normally high, goes low when triggered
'
You changed it to
InputTrigger var GPIO.5 ' Input normally HIGH, goes LOW to Trigger
InputReset var GPIO.2 ' Input normally HIGH, goes LOW to RESET
OutputLine var GPIO.0 ' Normally HIGH, goes LOW when triggered
Led var GPIO.1
The pinouts in my circuit (GPIO.0 , 1, 2 ) were transposed to ( GPIO.5, 2, 0, 1 )
The i/p and o/p are switched around, the trigger is on GPIO.0 you have it on GPIO.5, this is unused on my i/c, I also don't have a led (but I can add one tho if needed)
Cheers
Confused Dave..

Hi, G7
Just think a while ...
What you ask is to know IN ADVANCE if your input will be shorter or longer than 1 second ...
You can't know that before the second is elapsed ...
Just my two cents ...

Sorry Dave but, the code I used was the code in your original message, and pin assignements are clearly listed there the same as they were in my reply
' Define Hardware
' ---------------
InputTrigger var GPIO.5 ' Input normally HIGH, goes LOW to Trigger
InputReset var GPIO.2 ' Input normally HIGH, goes LOW to RESET
OutputLine var GPIO.0 ' Normally HIGH, goes LOW when triggered
Led var GPIO.1
'
The assignments in my reply are the same as in your first message on this thread. I can only think that your copy of the program has either merged together this file with another (Did yiou cut and paste ?) or something else is wrong.
Either way I happy that my reply and your first message use the same pinouts, as you will see when you check for yourself

Hi Chris
Beg your pudin, its been driving me mad for weeks, (I got in a right mess, thus the reason for the post on here)
I did cut and paste (several times) I have about 9 versions of the code here.
The mix up is I had cut pasted the original code from here for my 1st message,
I had changed it around to match my circuit, both did work ok.
(maybe I should had given up and gone down the pub)
With a clear head I have re programed the pic,
I have tried in my circuit and also bread boarded it.
Here's what I get when powered up,
GP0.0 high no change
GP0.1 low no change
GP0.2 high no change
GPO.3 high no change
GPO.4 high no change
GPO.5 high/low trigger (i/p toggle)
Your coding is re pasted below so you can check nothing was corrupted in the copy/past process.
Cheers..

It's alright Jeff,
I am merely interested to know if it works or not, and if not, what is the problem and I will try to help to rectify it.
Cheers

Hi Chris
Is there any updates yet, Have you got it working??
Cheers...
