Multithreading

[mfpktr]

Hi,

                     I am using LabVIEW for Creating a GUI, through which the user can change the target board register  values and read those registers. The communication protocol is CAN. l want to change the register values through user intervention,without effecting the process of reading the status registers in a timely manner. how shall i implement this? i think by using the concept of multithreading. Any body please comment on this.

You need to set up a multiple loop pattern, such as a master-slave architecture or a producer-consumer architecture. Read over the articles that I linked and take a look at the examples.

If you have your UI seperated from the actual CAN communications part you can do this. LabVIEW is easily multithreaded by having parallel loops. If the UI and the comms are in seperate vi's launched by a "Main" vi and communicate using some version of the producer/consumer model (queues, functional globals, etc.) they can be made pretty isolated from each other. There are basic  examples of these when you  use the "Help" pull down and "Find Examples"

I see my associate is a faster typist!

Thank you for the inputs.

I couldnot able to download the mastersalve example vi from the link.

anyboby please share me that zip file.

I did not encounter problems downloading the file. Perhaps it was a momentary server issue, or perhaps it could be a firewall issue. The example is attached.

Hi,

I need to parse a file and input the contents into a table. the data items in the file are seperated by "," and starts comment by "//". the table contains 3 columns two for data items and one for comment. i did this using Spreadsheet to Array converter pallete and possbile to fill two data items column. the delimiter used is ",", so the comment also coming along with second data item. How shall seperate the comment from data item without any modification in the input file.

Are you asking a different question? I'm not sure anymore since I don't know what you're doing. I don't know how you configured the Spreadsheet String To Array, but are you doing this:

Exactly.

I need to Print the Comment (Portion After "//") in another column without "//".

Also Please note after last data item in the file, there is no ",".

What are you trying to get as an output? A 2D array of strings? A 1D array of clusters? A 2D array of numbers for the first two columns and a separate 1D array of strings for the comments? What you want as the output will dictate how to do it.

please discontinue any further comments of the parsing in this thread.
