RA8875 LCD/TFT Graphic Controller Driver Library
--------------------------------------------------
Version:0.70b11p7
++++++++++++++++++++++++++++++++++++++++++++++++++
Written by: Max MC Costa for s.u.m.o.t.o.y
++++++++++++++++++++++++++++++++++++++++++++++++++
An attemp to create a full featured library support for RA8875 chip from RAiO.
Works with many SPI drived RA8875 Boards included Adafruit, Eastrising(buydisplay).
NOT work if you have a I2C or Parallel based display!

Teensy 3.1, a tiny MCU but monster of performances at tiny price, Arduino should learn...
Paul Stoffregen, the 'guru' behind many arduino magic, the father of Teensy
Bill Greyman, another 'maestro', greatly inspired many coders
Jnmattern & Marek Buriak for drawArc
Last but not less important the contributors and beta tester of this library:
M.Sandercrock, the experimentalist, and many others

TFT side Teensy/Uno
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
CLK: pin 13 UNO
MOSI: pin 11 UNO
MISO: pin 12 UNO
CS: pin 10 (selectable but note 1*!)
INT: pin 2 (selectable 2*)
RESET: pin 9 (selectable and optional 0*)
*(0) In some modules you can leave unconnected but check if it's needed!
*(1) On Teensy3.x not all pin are usable for CS! Read the printed paper
that come with your Teensy3.x for more informations!
*(2) Arduino cannot use any pin for interrupts! In my examples I don't use
interrupts but just reading pin state so you can use any pin :)
-------------------------------------------------------------------------------------
TFT side Stellaris (LM4F120XL) module=0 (still not checked)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
CLK: xxx
MOSI: xxx
MISO: xxx
CS: xxx (selectable)
INT: xxx (selectable)
RESET: xxx (selectable and optional)
*if you use an [optional] SD card here's connections...
-------------------------------------------------------------------------------------
TFT side Teensy2/Teensy3/Uno
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SD CLK: pin 13 [shared with RA]
SD MOSI: pin 11 [shared with RA]
SD MISO: pin 12 [shared with RA]
SD CS: pin 4 (selectable 3*)
SD CARD ID: pin xx (selectable and optional)
*(3) On Teensy3.x not all pin are usable for CS!
can be used: 2,6,9,10,15,20,21,22,23
-------------------------------------------------------------------------------------
TFT side Stellaris (LM4F120XL) module=0 (still not checked)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

SD CARD ID: pin xx (selectable and optional)
-------------------------------------------------------------------------------------
TFT side Teensy3 alternative setup
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
There are special cases on Teensy 3.x since it can be used for audio shield that remap
some pin. Using SPI in that situation will be impossible but you can use the alternative
pins definition feature of Teensy 3!
SD CLK: pin 13(normal),pin 14(alt) [shared with RA]
SD MOSI: pin 11(normal),pin 7(alt) [shared with RA]
SD MISO: pin 12(normal),pin 8(alt) [shared with RA]
SD CS: pin 2 (selectable 3*)
SD CARD ID: pin xx (selectable and optional)
*(3) On Teensy3.x not all pin are usable for CS's!
can be used: 2,6,9,10,15,20,21,22,23
