QUOTE(Steve Weidman @ Mar 8 2007, 10:29 AM) Also, how do I make this into a sub-VI? Every time I nest While Loops, the outer loop seems to stop running. Thanks, -Steve

QUOTE(Michael_Aivaliotis @ Mar 8 2007, 01:42 AM) Thanks so much for the VI. That makes pretty good sense. I can see how that will be able to latch the outputs from the min/max test. Now, what I also need to do is capture the output from a push button. I need the push button to do a user dialog for entering a serial number and to also start a test. Right now, I can capture the serial number fine by using a momentary push button that triggers a case structure with the dialog in the true portion of it. But what I also need to do is capture the fact that the push button has started my test running. This is going to be really simple to put into what I already have if I can "capture" or latch the fact that the push button has been pressed. I want to latch that so that additonal clicks to the push button don't do anything until the test has been completed. Did that make sense at all? Thanks, -Steve

QUOTE(dsaunders @ Mar 7 2007, 12:42 PM) I thought about using the switches instead of the push buttons, but I really need it to do both. I have a case structure that needs to operate once, and I also have a routine that needs to run for an extended time (ie my need for the latch). Also, I need the latch to show a condition. I have an In Range and Coerce function that if a signal ever drops too low or goes too high, the In Range function's output needs to be latched for the entire time of my test. It will not be reset until the beginning of the next test (which is started by a push button). I'm open to any ideas... Thanks, -Steve

QUOTE(dsaunders @ Mar 6 2007, 03:46 PM) Thanks for the input. I knew about the button's actual latching function. Unfortunately, this is not going to accptable since it goes away once LabView reads the switch. Now in regards to a shift register, do any of you have examples of a scheme that will allow me to "capture" the fact that a button was pushed and use it in the rest of the VI until I'm ready to discard it? Thanks, -Steve

I'm still very new to LabView and need some help. I would like to capture the output of a button and latch it until I reset it. Is there any kind of a latch function that can capture and hold boolean values until I reset it? Thanks, -Steve

The number of bytes to read on the VISA read function. I didn't figure it would hurt anything, but wanted to make sure. Thanks, -Steve W.

I may have to set my "read" constant fairly high (like 1000 or more). Is there a problem with doing that? Thanks!! -Steve W.

That seems to be working well too. I put a while loop around it and it seems to be kicking my data stream out perfect every time. Thanks so much for the help!! -Steve W.

Sorry for the delay in getting back to you. Lots of things to do here. Thank you so much for the VI. That appears to be exactly what I'm after. I should be able to test it later today. Again, thanks so much for the help!! -Steve W.

That's an interesting idea concerning the missed data. That may be what's happening. While I pull together the other information you asked for, could you explain how I can make a queue to store the intermediate data? Thanks! -Steve

Good Morning. I'm new to LabView, having just gotten the version 8 full development suite. Overall, everything has worked out great, but I'm having trouble reading a processing a serial string. Here is my situation: I have a three wire serial port (no flow control) running at 38400. Twice per second, my instrument sends out a comma delimited data stream with a CR on the end. I need to capture the whole data string and take it apart at the commas. I know how to take it apart, so no problems there. By using the "bytes at port" connected to the standard serial read, I can see my data. At times though, it gets "out of sync" for lack of a better term and doesn't capture the whole string. I thought that maybe using events, might capture it, but no luck there at all. Any ideas or futher clarifications for me? Thanks!! -Steve Weidman
