How to use queues within continuous data acquisition?

[Maître]

Hello,

I want to use queues to save data from a load cell. Data acquisition needs to be continuous. I have tried something, but it's not working! The problem is that with my VI 'essai_8', the data is not acquire continuously.

Thank you for your help.

Here is a way to do it if you really want to use queus. I changed a lot in vi to many things to list just have a look. here is a copy in version 7.1. what version of LV are you using.

I have also included a way to do this without queue

I'm being a little picky here, but since Joe Hoskins is a Tennessee Volunteer and I'm an LSU Tiger, I feel compelled to show him up. 

If the producer loop ever has an error, the consumer loop will keep running until the stop button is pressed.  One should put in an error check as shown in the attached vi.  If the producer loop develops an error and ends, and the queue is closed, the consumer loop will produce an error when trying to read from a closed queue and it will stop automatically as well.

Joe:  Good luck to the Vols, that is until LSU marches into Knoxville this autumn.  Remember, we owe you one for ruining our perfect season last year

OK you got me on that one, however you to could improve on your code and make it to where the LVM does not execute when there is an error.Of course we could go on and on but some of us do not have the time. Got to go put out some fires.

Were going to need the luck this year, it's good to see you back on the forum again. Hows the heart.
