It has been a long job ; because I have tested all SPI signals and they have worked pretty well, but the display didn't show to me something.
At the end, I have found all bugs and fixed it for last version of Arduino IDE, the version 1.6.4.
Now, you can use it without problems; after an upgrade of Arduino, if you use a previous version.
This is the video I made some minute ago for a small preview (excuse me for video quality).
It works up to 40Mhz... right now.
