How can I generate a component array using JBuilder?

Question

Now I'm using JBuilder to design my program's GUI. I wanted a JTextField array like this:nums[0]~nums[2].So I draged three JTextFields into the container at JBuilder's design view. But when I set the names of them as nums[x](x=0,1,2). I got a Error Message. It told me that I used a illegal name. How should I do, please?
thank you a million!

Answer 1

The DIO ports on a MIO will not satisfy your needs (unless you move to LV RT).
They do not support buffered outputs.
Your update rate (how often you can set the port and clear it) is going to be limited by how fast (a-hem slow) windows will let you iterate,
and,
be non-determinstic.
You could use,
1) LV RT with the existing board, or
2) FieldPoint PWM module, or
3) Arbitrary waveform generators, or
4) HS DIO board, or
5) use the analog output of your baord where you que-up a 0 -5V waveform of the proper shape (i.e. make sure that the duty cylce fraction of the update values are high, the rest low).
This is just to get a PWM signal out.
Now there is another issue. Determinism. How often do you plan on reading your inputs and making a change to you
r PWM? If you plan on doing more often that 10/second, write your code to handle windows going out to la-la land when you expect it to be working.
Can you tell I like LV-RT.
I hope my ramblings have helped.
