My project involves designing a front end for a synchronous generator using LabVIEW. It is actually data acquisition and display of signals in a file. The problem I face when building a program is that: 1)the sampling rate is set to 100 samples with 1 kHz sampling frequency.These signals are generated by daq assistant and i have used merge signals to merge these signals from daq assistant as well as signals from other radio buttons and Boolean as well. The problem is that when written on a file I am able to see only one instance of Boolean status for every 10

Hey all, I am trying to create a fairly large program. What I want to do is for someone to upload a text file, customized so I can create statements for it, and then labVIEW will read the the text file and perform actions. Specifically, the text will contain pin numbers, on/off status, wait delay, and another on/off status. The pin numbers correspond to a Boolean indicator array. The on/off status tell the Boolean indicator array to turn on/off. The wait delay tells the program to wait how long before changing the indicator array value again, and the second on/off status turns the

Hello guys! Is it possible to parse and evaluate a boolean expression stored in a string with standard LV VIs? I can't find anything.. Expression like this one: 1==2 && (2!=5 || 2 > 5) I'm building a configuration xml-file with if-attributes for conditions: <item name="xyz" if="{namespace:variable} == 3" /> The first step is replacing the variables within {} with actual values. This is the easy part. The hard part is to evaluate the results...

Howdy, I am having trouble coding a VI. I am wishing to make boolean based vi in which the user has to select a choice which color is brighter or dimmer? I want to randomize the choices so that it isn't always making a higher choice or alternate the presentation. I want to record the time of presses with the millisecond counter vi. I also want to record the number of correct and incorrect choices so that if they get 3 correct the colors seem closer in brightness and shift the color choices close to matching after 3 correct guesses until they get 3 incorrect guesses. Any insight on how to do
