Hi, i'm quite interested in updates of your project, mainly because i have a similar project ongoing. What i have is a 8x8 RGB matrix, with a colorduino and currently i am driving it at 15-20fps with 253 brightness levels. My first test is a program in C# which captures realtime screenshots and feeds them to an arduino. that way i can test a whole bunch of things like video, color test patterns etc without the need to modify the code since all i'm doing is streaming a portion of the desktop.
this is my thread if you want to read more. i can also provide you with some more code...
i am really getting awesome results with video
I will follow your thread to see where this is going.
