Hello,

I have a new LEAP motion sensor. I installed it and also the library, but when I start to run the processing sketch basics, its looks like that (picture).

Thanks in advance for the help

Daniel

Hey,

Please put your code by :

1. Pressing `Ctrl+T` in the Processing editor IDE
2. Format your code with the `</>` button in the message editor.

So people can help you understand the error 🙂

I am using the basic code of leap motion, Which came in the example of the library.  
I connected the leap contoller but it doesn work properly in Processing.

Hi danyman,

Did you find a way to solve it? I’m running into the same problem. The Leap Motion Visualizer recognizes my hands, but when I try the code (even with the examples given by the library) Processing won’t recognize my hands.

The Processing version I’m using is 3.2.3 and the Leap Motion Software v2 (2.3.1+31549) in Windows 10 (Idk if this last, might be the problem).

Thanks in advance,

Hi - I have had a similar, or at least probably related, problem just now. See [this post](https://discourse.processing.org/t/processing-does-not-find-device/24193)

What works for me is \<_deleted_\>. _edit: Sorry, I was wrong, starting sketch before plugging in the device was NOT a reliable solution. What seems to work is to upgrade the LEAP software to version 3.2.1, as described in my reply to the post mentioned above_

Hi,  
Me to, similar problem.  
Windows 10  
Orion 4.1.0+52211  
Firmware revision: 1.7.0  
Processing 3.5.4  
Library “Leap Motion for processing” 2.3.1.6 (installed from the library manager)  
When trying the LM\_1\_Basics, I get this:  
Leap Motion Library v2.3.1.6 - Leap Motion SDK v2.3.1+31549  
and then nothing…  
Is there anybody who knows how to make it run?  
Thanks

My progress:  
Orion 4.1.0+52211 (default latest driver proposed for Leap Motion website): there’s no java sdk in.  
So I uninstalled and installed Orion 2.3.1+31549 that you can get here: [https://developer-archive.leapmotion.com/v2?id=skeletal-beta&platform=windows&version=2.3.1.31549](https://developer-archive.leapmotion.com/v2?id=skeletal-beta&platform=windows&version=2.3.1.31549)  
and the fix for windows from here: [[RESOLVED] Windows 10 Fall Creators Update Bugfix - Customer Support - Leap Motion Community Forums](https://forums.leapmotion.com/t/resolved-windows-10-fall-creators-update-bugfix/6585)  
And then it worked… for a while ☹  
after a few moment, it doesn’t work anymore.  
So I just tried with Orion 3.2.1+45911  
Seems to be better. It just stops when I put my two hands on. But maybe because I’m in usb2. I’ll try on a usb3 port.  
Well, at least, I can start playing with processing!

uninstalling the last LeapDeveloperKit\_4.1.0+5511 and installing the LeapDeveloperKit\_3.2.1  
worked for me, after doing it so I was able to finally see the leap data in processing, instead of just the white background from the test sketch.
