Hi
Here is the Nagilos C# Wrapper for Dr Lavas UDAC modified and working for me with Etherdream + UDAC.
The principal change I made is on the struct LaserPoint, now its a new class with 3 different constructors.
This consructors put all colors to 0 value when we have blanking. 2 of this constructors are for multicolor systems, but public LaserPoint(Point punto, Boolean visible) does not supports multicolor. its for my poor green laser.
I also made some adjustments in order to get Etherdream working for me so if you are using a different DAC you must change using (var instance = DAC.Initialize(ControllerTypes.All, ControllerType.EZAUDDAC))
The example code is for a multicolor laser so if you have a green laser your circle wont show complete and you must use the monocolor constructor.
Thanks again to NAgilo, he give the key and nowI have a entire house.
