pulse counting with voltage input
Hello cfpboy,I have a question about your signal first.  How long does your signal remain changed when a pulse occurs?  Does the signal stay "high" for 1 full second and then go "low" or does it pulse "high" once a second and then immediately return to "low".  If it stays "high", then you could simply po... 6 May 2008 23:25

Configuring/reading multiple signal types from one module viaserial port
Rasheel,   I put the VISA Configure Serial Port VI, as well as the VISA Close VI outside of the loop (I kept the VISA CLR VI inside the loop), but I still continue to get variations in temperature and mA readings.  However, there is never any "disturbances" in the voltage reading.  Any other ideas? &n... 7 May 2008 15:04

QUIT LabVIEW.vi works differently in LC8.2
Similar issue here solved, code looks like this...   Init routine - while loop containing event structure - Cleanup - Quit-if-Exe   1.  Exe will not quit if event structure contains the <Application> Instance Close (not Instance Close?) 2.  Even though event structure is no longer executi... 6 May 2008 23:25

tabbing order in tab controls
Hi leachdor,When you change the tab order of a specific control in LabVIEW, it must then re-order the other controls in order to ensure that each tab order value is only applied to one control, and that there are only as many tab stops as there are controls.  As such, there is no way to simply re-order a single co... 6 May 2008 23:25

Time Stamping Signal from NI9422
Hello All, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I am trying to use the NI cDAQ-9172 with a NI-9422 module and I am trying to figure out if the following can be done with LabVIEW.&nbsp; What I need to do is whenever I get a signal on the NI-9422 I want to time stamp the signal with the current date and time... 7 May 2008 10:08

Have problems in using Labview program contains &quot;niScopeMulti Fetch&quot; unit to sample data from PCI 5922
Sounds like you are doing too much in a loop.&nbsp; You must fetch samples fast enough to avoid buffer overruns.&nbsp; If you save data in the sam loop as the fetch this becomes a distinct possibility, especially with more channels high acq rates.&nbsp; Your fetches become large so writing to file can be slow causing y... 6 May 2008 23:25

Re : Re: No Data Change event generated for a XControl in aType Def.
Hi Matthieu, Indeed your link is about the Data Change event of XControls. What I find interesting is that your link is about situations in which the Data change event is unexpectedly triggered twice whereas this thread is about the Data change event not being triggered at all, not even once. :-) Thank you for this i... 6 May 2008 23:25

Writing many small waveforms to an HWS file
Joe F., Thanks for the information.&nbsp; I figured that I would be better off just writing a binary file.&nbsp; As for viewing and analyzing my data, I plan to write my own tools and the number of data points will not be a problem.&nbsp; The framework I use for building the analysis program has tools for reading hdf f... 7 May 2008 00:21
