Well, I am a newbie. Thanks for taking the time to help me.
I'm on windows 7, running Kodi addon and "hyperion screen capture".
I have hyperion running on a pi2. I was trying to try this, with a WS2813:
To try step by step, I first followed this:
(connecting arduino to pc, trying to get Colorswirl.pde to work). Got that.
I have hyperion installed on my pi and "hyperion screen capture" says "enabled", Kodi addons gives no error so I think they (windows pc and hyperion on pi) are indeed connected.
BUT when IN HYPERCON, tab ssh, I press connect, I get an error (see attachment):
I'm not sure what to enter in Target ip (think it should be the ip of the pi or maybe the port to which the arduino is connected).
I DID get it working once, but I have changed to much I can't remember. I wanted to uninstall and reinstall hyperion but for that I also need a ssh-connection in hypercon.
So, I'm stuck here, Any help appreciated.
