A 128x64 GLCD for Teensy 3.x

The aim of this project is to use a high-speed port to transfer eight bits at a time on a graphical display 128x64. To do this I have studied a suitable configuration of Teensy I/O and also have modified the KS0108 library, as described in my post "Teensy rev.3.1 and KS0108 Graphic LCD library". For more information and details on the proposed project see the two posts on my blog: http://ardupiclab.blogspot.it/ where I put also the link of the modified library.
