Trouble with spike and camera

[hasin5]

Hey, thanks for the great advice. We managed to access the relay file but we don't understand what the "visible" means... can you please elaborate on this?

I'm sorry, I don't know what you are referring to.

[hasin5]

In the relay example, with in the case structure, there are two blocks that say visible.... What are those? And if you don't see that... Then what in general is in that case structure? -Its called the property node

[Alan Anderson]

That case structure is only providing visual feedback on the example's front panel. It plays games with the LED indicator on the picture of the Spike so it can have more than two states. Don't worry about it, and certainly don't copy it to your code.

All you need are the Relay Open and a RefNum Set in Begin.vi, and a RefNum Get and a Relay Set in Teleop.vi (or wherever you need to set the state of the relay).

We would like to be able to set the spike so that it goes forward when we click a button and then it reverses when we release the button. How would we go about programming this?

Here's one way, ignore the name given to it.

How do we create the "Forward" and "Reverse" for the Teleop.vi? We are getting a boolean input and output and we dont know what to replace it with.

[Mark McLeod]

On the Relay Set, right-click on the input node and choose Create -> Constant
Then break the wire and drag and copy/paste it wherever you need to place it.

If you post an image taken with the camera, I can give my opinion as to what is causing the blur.

Here is the camera image btw for the person wondering.... It also freezes randomly.

It expects us to put a boolean input (its orange - not blue) - therefore, we get an error when we connect it to the relay set.

[Mark McLeod]

Start with a new Select and it will have several orange floating-point nodes and one green boolean node.
The first thing wired to an orange node will change all the nodes to that type color.

we got the spike working!

now we need help with the camera -> we need to set it up for targetting.

We had to restore our camera to factory settings and set it up again. Now it is not blurry, but we can not get an image to appear on the dashboard. Any ideas?
