LED Matrix Studio 0.8.6 beta January 2nd 2016
The LED Matrix Studio is an application designed for electronics enthusiasts who want to speed up the development of their LED and matrix projects. It supports many different export options, animations and different sizes of matrix.
Comes with example Arduino files demonstrating use of exported data.
I have used this with Sure Electronics 32x8 and 24x16 LED boards, Adafruit 8x8 bicolour matrix, custom LED matrix, and generic 8x8/5x7 single colour matrix.
