Time base for a set of values

[aldus]

Hi,

     i have a set of values (0-359). According to each interval i have to give the each set of value (0-359) to trigonometric functions. i am setting the interval. Is there a way for it?. Can i use cluster(for set of values) and timer for the interval?

Where did these values come from? If the data is formatted as a waveform, you can set the t0, as well as the dt -- assuming the interval between values is constant.

I don't understand the question about the timer. Are you generating an output waveform? The problem with timers is that you have the latency of Windows getting in the way of deterministic timing.

No i am not generating any waveform. i am entering these values (0-359) . it is an angle degrees. corresponding to each degree of angle i need to get the sin/cosine of the angle what i am giving. the interval can be (1/360), (10/360). by these interval values i need to increment the angle degrees. then i want generate the sine/cosine of that angle.

I don't understand where a timer would be involved. Have you looked at the Ramp Pattern function?

i am incrementin the angle by some intervals, instead for the incrementing purpose can i use timer for that.

If you want to increment every x number of milliseconds, use the Wait (ms) function. If you want to increment x number of degrees, then you use the Ramp Pattern to create the array and a for loop.

Thanks Mr.Dennis_Knutson,

Can you help me how to use the ramp pattern to create the array and a for loop. Can you give me an example

[Dennis_Knutson]

Just read the context help for the function. You have two options for the pattern.

An array that is passed into a for loop will be automatically indexed, one element at a time. This is something covered in basic LabVIEW tutorials.
