After sorting through examples and these explanations. I've began to realize that what I want to do is almost as easy as using one of the provided LabVIEW examples. My old program wouldn't write because I never allowed it enough time, before I looped through it again. If I introduced a time delay before clearing the task, I would get a sputtered waveform output. Which won't work, I need a nice smooth output wave.
The example that works great is the "continuous generate waveform voltage with internal clock" which I attached. The only problem is that I need to be able to change the amplitude of the sine wave while it is running with the click of a button. For example, the program can run continuously with an amplitude of 5. But when I press a button, the sine wave must change to an amplitude of 10 for 0.5 seconds. On a previous post, a user helped me identify a way to do this using shift registers and the "get time" function and then comparing the times in a loop until the difference exceeded my time of 0.5 seconds. But that was with my previous loop program which didn't use the waveform timing and the output sine wave was really choppy.
In this example, I don't see how you can change the amplitude of the sine wave. Is it even possible, or do I have an impossible task??
