I came across what appears to be a bug with the way that Xlights uploads something to FPP.
The lights are single channel lights connected to a 2811DC30 which is a 30 dc dimmer which acts like 10 pixels as far as any pixel controller is concerned.
The attachment shows the xlights setup which I "think" will be as right as it can get for this setup.
When uploading the setup to FPP (which sadly I can't screenshot as it was on someone elses computer and I changed the settings after I diagnosed the problem) the 20 single channel props starting with H_Hip_L on channel 218890 and going through to channel 281909 there is a bizarre action.
What is expected is below
Port 2
Prop Channel Pixels End Channel
H_Hip_L 218890 1 218890
H_Hip_Rt 218891 1 218891
What appears in FPP is ODD
H_Hip_L 218890 1 218889
H_Hip_Rt 218891 1 218890
It's somehow allocating minus 1 channel for the prop.
To get going I changed to
Hips 218890 10 218920
Working like this is fine except any channel changes to Xlights will now screw things up as auto upload is turned off for this controller to stop the weird channel config being uploaded. Prior to Xlights being able to push data out to FPP and other controllers it was just a process of assigning a single channel and in the controller linking that channel. The new process is much easier and I hope that there is a solution to integrate Xlights and FPP together without my weird board and single channel lights causing a problem.
thanks
