Labview calculator

[Country Loon]

I need a calculator type display so that when I type a number from a keypad
(like a phone) the number goes into a display and scrolls along. Any ideas?

Actually I figured out how to do this - for anybody who is interested by
using concatenate strings and registers.

In the Express VIs (LabVIEW 7.0 and later) there is a Formula Express VI. It has a calculator interface. you might be able to use it as is. If not, you can open the configuration VI for it and see how NI did it. This VI is on the functions palette at Express -> Arithmentic & Comparison -> Formula. The configuration VI is at LabVIEW\vi.lib\express\express arith-compare\FormulaConfig\Configure Formula.vi .

It basically uses a while loop with an event structure. It has buttons that you can press with a mouse, or you can just type into the display. The result is sent into a formula node.

I hope that this helps,

Hello,

Here is a nice calculator example built in LabVIEW.  You will need LabVIEW 8.5 to view it.  Check it out!

Hi mathan,

It looks like you edited a subvi and you just need to right click on it and select re-link to sub vi.

Hai,

Am sorry. Actually i opened it directly from zip file. That's why i got that problem. But now after extracting the zip file into a folder, everything works fine now. Great work in building that calculator.

Thanks for the support,

Mathan
