A project log for Number Matrix V2

Version 2.0 of my number matrix. Will be 4 times the size and have grayscale.

The display will consist of 16 display boards that each hold 32 quad seven segment displays and all needed driver circuits.  The display boards will use a HUB75'ish style control but with the data lines paralleled for lower clock scan rates.  This means that all 16 boards are updated at the same time so there is no performance degradation for making the display bigger.

Originally I started off with a simulator based on the Seven Segment Sign SSS Documentation.  It is written in Python and has some real performance issues.  After realizing that was not going to work I went back to the original simulation I made for the V1 display and ported it over to use CodeBlocks with the MingGW compiler and OpenGL.  The same build works both on a WIndows PC and the PI with only changing the version of GLUT being used.  Will eventually get the code on GitHub as I would like to see if anyone wants to help create animations or anything else for the display.
