I have had some time to sit down with the 4d display and have got it to read the data stream from the controller.
Well not exactly the controller, but a virtual controller using the arduino that I was originally going to use for this project.
I have attached the arduino sketch, it's just a very simple loop that spits out a data stream.
So the display can read the ascii data stream, just have to get it to store the data in some variables, but this bit has me stumped at the moment. So I have posted a question on the manufactures forum.
Can't extract numerical values from ascii string. - 4D SYSTEMS FORUM
