Hi guys! Just an easy question that you probably know how to fix, but for me this is giving me headache I got just this very simple example based on my big program. I empties an 2D array, put something in the array, and displays it in a system table using shift register. In my frontpanel everything goes as planed, but the table flickers. I have tried to put in longer delays, and the flickering stops around 4-5 seconds. Unfortunately this will interfere with the rest of my program. I cannot have 4-5 seconds of delay on each interation in the mainwhile loop, when I also wait for the user to click different buttons. The whole program will then be very "slow" to use. Is it the place i put the table that makes this problem? If you try my program, do you also see flickering? Maybe it's only my computer. Created in LV2010 BDS.

I dont have 2010 on this PC but this might be an architecture question. You should not rewite a table faster than the user needs to read it (1/sec maybe slower). You should consider a state machine, and most likely an event based sm. The table can be updated in a stae when new data is avaliable or when a certain timeout has occured. The simplist way to slow down a part of a loop (not most elegant though) is to put a case structure around the write and wire the boolean to an elapsed time vi. This will not slow down your loop (probably speed it up infact) but would slow the table update down to a managle rate.

System table flickers

Solved!

Read David's message #6 again. You can resize it to be a very tiny decoration and put it on a part of the table that won't interfere with your cut/paste operations.
