Convert 8.2.1 to 7.1

[GerdW]

Hi Derek,

not one by one, but parts of you project!
Usually I structure my programs into several parts (like: input/settings, measurement, output) by subvis. Each main part is divided into several sub-parts... I would try to save those parts/subparts individually to find the problematic vi.

Hi abhilasha,
 
I converted the vi to LV71 and LV80... In LV71 some errors appeared because of missing items.

But:
This vi will not run as intended - you use to many local variables.
In fact you don't need any of all those locals - use wires instead. In LabView the wire has the functionality of variables in text programming!
And using locals like you did only introduces race conditions!

And I also didn't check those formula express vis: when they only contain simple formulas you should replace them by primitive math functions...

I just got 8.5 and in my joy of playing with a new toy I accidentally changed chunks of my code originally written in 7.1.  We have 7.1, 8.2 and 8.5 and without 8.0 am not able to get all of the way back to 7.1 and would prefer not having to re-write it all.

It seems to be implied previously in this thread that with 8.5 I should be able to save a couple versions back but  "File>Save for Previous Version..." only gives me the options for 8.5, 8.2, or 8.0.  Do I need to look elsewhere to convert to 7.1 or start looking for a disc of 8.0?

Correct.  8.5 gives you a couple versions back,  which are 8.2 and 8.0.  In order to go back to 7.1, you will need to have 8.0 installed, or find someone who does.  If it isn't too many VI's, you could post them on the forum and someone may be able to do the conversion for you.

We lost our main 8.0 disc so I am going to try the French version tonight and hopefully it does not change everything to French when I convert to 7.1.

Could someone convert this to version 7.1 for me?

Hi mfried,

here's the LV7.1 version...

- I made some changes and comments to CANUSB_Tx.vi. Read them!
- In CANUSB_Demo.vi you should create a shift register to hold "messages" instead of using locals in each event case...

Thank you so much.
