Do not understand why "the node fpga Audio IN Terminal is 16-bit signed integer"?
Hello
I work with myRIO 1900 for my project of ANC.
Audio IN of the fpga node gives its type terminal data as integer signed 16-bit. So, finally the exit on the nodes of the fpga is fluctuating between two values - 1 and 1. But I want the actual values of the audio data, I did not understand how to address this problem.
Audio In on the side of RT gives type of terminal of data such as actual values, but I did not understand why the terminal of Audio In FPGAs is 16-bit integer. ??
Please help me solve this problem.
Thank you.
If your analog range of +/-2.5 V. 32768 then--would be the equivalent of-2.5 V. 32767 would be + 2, 5V.
If you get + /-1 V, then you should see somewhere between + / 13 107 on the analog input of the number I16.
Basically, take the n ° I16, divide by 32767, multiply by 2.5. You will have your analog input in volts.
I don't know why you thing it's just rounding up to the-1 to + 1. Something must be wrong with your code or configuration.

In the attached VI I do not understand why given domestic business structures are not transferred in the table.
Thank you.
The VI has yet InfoCluster.ctl.
If you don't bring anything in the cluster, you should always pass the cluster via. You run the same question ' use default if Unwired "as before. The presence of these "case bundleless" begs the question why you have these States because they do nothing.

When I copy something from one page to another, it seems to change text color or background, that I do not understand why he never used to do.
Whether it's text or only a shape it changes its color to something else when I copy and paste on.
Do you mean 'page' or 'site '?
If you copy something from another site, the reason may be, to have different, but all also named colours on each site.
It would be normal and causes the noticed effect.

I do not understand what the function of the Pseudo-classes
I do not understand what the function of the CSS Pseudo-classes 'top', 'right', 'bottom' and 'left' in a tab pane.
Could someone explain to me? Can you give me an example?
Another thing... How to center the tabs in a tab pane?
In advance thank you very much to allI do not understand what the function of the CSS Pseudo-classes 'top', 'right', 'bottom' and 'left' in a tab pane.
They are related to the side property.
http://docs.Oracle.com/JavaFX/2/API/JavaFX/scene/control/TabPane.html#sideProperty
The property side is where the tabs are placed with respect to the visible tab pane.If you do not use this property, you don't need to worry their about to much.
The default value for the side is high, as the pseudo-class flaw that will be active.Another thing... How to center the tabs in a tab pane?

The administration server is not reachable from the node target via HTTP (S)
Hi all
I tried add Host in Oracle 12 c. I previously added Linux host OS, but I couldn't add OS AIX in 12 c. I did the auto update for Agent of AIX. You can find my OS and DB info on below.
Server Oracle 12 c - OS is SunOS 5.10
Client host Oracle 11.2.0.1.0 - OS is AIX
During the installation, I got this error message "the administration server is not reachable from the node target via HTTP (S). In topology, we do not use any firewall... As I said I've added Linux and SunOS but AIX does not...
How can I solve that?

Why the nodes are placed on web sites that I discovered with fire fox but not other browsers
When you view the web page with fire fox is someone changing words and inserting nodes on the site. This does not happen with chrome or explorer. When I inspect the element it is HTML not allowed more written on the site. I have remove the node (a commercial that redirects the browser), but they pop up.
You can check the suspicious extensions or recently installed unknowns.

Understanding on the 9505 FPGA VI speed control
I was able to quickly use the 9505 Servo Drive example for closed loop control of position on the FPGA, but I can't find how to change the code to take in charge the speed control (which I need to another axis). I'm doing my changes on the FPGA VI itself rather than on the side of RT Softmotion.
Here are the questions I have:
If I use the PI speed loop with my speed and a set arbitrary control speed, I see the speed stabilizes (engine power seems uniform), but I can't correlate with the other speed reference that a larger number is faster. Speed (from the loop of the encoder) seems collating in values from 0 to 2 just on my FPGA VI (I do not understand the units, but I see my position change on my collation of encoder in thousands of pulses per second). Why are they so different/how I have adapted my encoder speed correctly?
Using just the delivery example 9505 Servo Drive (position control), how to set the speed of moving of the FPGA code (in interactive mode)?
Hello
Speed is defined through position set points. Control of the speed in the screw RT does not actually send speed commands to the reader, but sends position set points at a known rate. Given that the position set points are sent at a constant rate, an effective speed can be calculated.
A method to do so via the FPGA would synchronize a loop in your FPGA code for the analytical engine, which has a known rate. Once this is done, you can calculate the actual speed of the engine.
