varying constants in a loop

[dmg3588]

I have a VI that drives two servo motors with a sinusoidal input. Currently these inputs have a constant frequency. Is it possible for me to have the inputs vary within a range of two different values for as long as the loop is running?

Thank you.

So, do you want to randomly generate the inputs between the two ranges?

Random works. Ideal would be a sweep from say 0.001 to 0.005 and back.

And you're initializing the COM port twice in the loop because... ?

Generate your array of values using the Ramp Pattern VI. In your loop pick out the required element as a function of the loop iteration modulus the size of your array.

NOTE: Do not have the VISA Configure Serial port inside of loops. Initialize once outside the loop, do your communication inside the loop, and then close (once)

Hi!!

I have to create simulation of biology system and now i'm stucked with the case of changing the value of the constant. I mean I want that the program will change the constant automaticaly to run the relative simulation to study the influence of the parameter variation on the system dynamics.
