Trying to use ViewPort agan.

Help! For some reason I get an error that doesn't make sense at the moment. The error message is:

"Could not start running. Ensure your Propeller is connected and try again.
Details: Error in your vp.share(@a,@b) line. ... You're currently shariing 1260 bytes. That's too much!"

What ever I do to that line I get the same number of bytes error. I copied this 'vp stuff' from another program and edited it for this program. I need to look at some I/O activity (interfacing to a MagTek card reader) and find this 'barrier' in my way.

With VP stuff commented out the program runs fine.

Hi Harley,
I took your code, commented out all the objects I didn't have, and then ran it with ViewPort v4.55
No Problem...
(See attached for archive of what I did)

Hanno,

Thanks for taking the time to look at my problem. My version is 4.2.7. Should that make any difference for using only LAS?

I'll have to look over what your code vs. mine is to see what's in error. Frustrating when such happens; one is ready to work and some new barrier seems to come up. I figured I only needed to copy/paste and edit for what variables this program uses and it should go. Hours later no progress before I posted my problem.

Hanno,

I downloaded VP ver 4.5.3 and after having to fiddle around with getting my source and associated files into into it's Tutorial, finally got it working today.

Seems with every update, there is so much that has to be moved. Will have to reread the manual for the proper placement of files.

Nice to note the Trigger polarity issue in LAS is fixed. Nice to see the red flag on triggering (Wait for Trigger) too.

Hi Harley,
Glad you got it working! Sorry to "keep you on your toes" by changing things- that's the price you pay when I fix things
