This is a library for the Adafruit 2.8" TFT display.
This library works with the Adafruit 2.8" TFT Breakout w/SD card
----> http://www.adafruit.com/products/335
as well as Adafruit TFT Touch Shield
----> http://www.adafruit.com/products/376
Check out the links above for our tutorials and wiring diagrams.
These displays use 8-bit parallel to communicate, 12 or 13 pins are required
to interface (RST is optional).
Adafruit invests time and resources providing this open source code,
please support Adafruit and open-source hardware by purchasing
products from Adafruit!

To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder Adafruit_TFTLCD. Check that the Adafruit_TFTLCD folder contains Adafruit_TFTLCD.cpp and Adafruit_TFTLCD.
Place the Adafruit_TFT library folder your <arduinosketchfolder>/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE
Also requires the Adafruit_GFX library for Arduino. https://github.com/adafruit/Adafruit-GFX-Library

// IMPORTANT: Adafruit_TFTLCD LIBRARY MUST BE SPECIFICALLY
// CONFIGURED FOR EITHER THE TFT SHIELD OR THE BREAKOUT BOARD.
// SEE RELEVANT COMMENTS IN Adafruit_TFTLCD.h FOR SETUP.
#include <Adafruit_GFX.h> // Core graphics library
#include <Adafruit_TFTLCD.h> // Hardware-specific library
// The control pins for the LCD can be assigned to any digital or
// analog pins...but we'll use the analog pins as this allows us to
// double up the pins with the touch screen (see the TFT paint example).
#define LCD_CS A3 // Chip Select goes to Analog 3
#define LCD_CD A2 // Command/Data goes to Analog 2
#define LCD_WR A1 // LCD Write goes to Analog 1
#define LCD_RD A0 // LCD Read goes to Analog 0
#define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin
// When using the BREAKOUT BOARD only, use these 8 data lines to the LCD:
// For the Arduino Uno, Duemilanove, Diecimila, etc.:
// D0 connects to digital pin 8 (Notice these are
// D1 connects to digital pin 9 NOT in order!)
// D2 connects to digital pin 2
// D3 connects to digital pin 3
// D4 connects to digital pin 4
// D5 connects to digital pin 5
// D6 connects to digital pin 6
// D7 connects to digital pin 7
// For the Arduino Mega, use digital pins 22 through 29
// (on the 2-row header at the end of the board).
// Assign human-readable names to some common 16-bit color values:
#define BLACK 0x0000
#define BLUE 0x001F
#define RED 0xF800
#define GREEN 0x07E0

#ifndef _pin_magic_
#define _pin_magic_
// This header file serves two purposes:
//
// 1) Isolate non-portable MCU port- and pin-specific identifiers and
// operations so the library code itself remains somewhat agnostic
// (PORTs and pin numbers are always referenced through macros).
//
// 2) GCC doesn't always respect the "inline" keyword, so this is a
// ham-fisted manner of forcing the issue to minimize function calls.
// This sometimes makes the library a bit bigger than before, but fast++.
// However, because they're macros, we need to be SUPER CAREFUL about
// parameters -- for example, write8(x) may expand to multiple PORT
// writes that all refer to x, so it needs to be a constant or fixed
// variable and not something like *ptr++ (which, after macro
// expansion, may increment the pointer repeatedly and run off into
// la-la land). Macros also give us fine-grained control over which
// operations are inlined on which boards (balancing speed against
// available program space).
// When using the TFT shield, control and data pins exist in set physical
// locations, but the ports and bitmasks corresponding to each vary among
// boards. A separate set of pin definitions is given for each supported
// board type.
// When using the TFT breakout board, control pins are configurable but
// the data pins are still fixed -- making every data pin configurable
// would be much too slow. The data pin layouts are not the same between
// the shield and breakout configurations -- for the latter, pins were
// chosen to keep the tutorial wiring manageable more than making optimal
// use of ports and bitmasks. So there's a second set of pin definitions
// given for each supported board.
// Shield pin usage:
// LCD Data Bit : 7 6 5 4 3 2 1 0
// Digital pin #: 7 6 13 4 11 10 9 8
// Uno port/pin : PD7 PD6 PB5 PD4 PB3 PB2 PB1 PB0
// Mega port/pin: PH4 PH3 PB7 PG5 PB5 PB4 PH6 PH5
// Leo port/pin : PE6 PD7 PC7 PD4 PB7 PB6 PB5 PB4
// Due port/pin : PC23 PC24 PB27 PC26 PD7 PC29 PC21 PC22
// Breakout pin usage:
// LCD Data Bit : 7 6 5 4 3 2 1 0
// Uno dig. pin : 7 6 5 4 3 2 9 8
// Uno port/pin : PD7 PD6 PD5 PD4 PD3 PD2 PB1 PB0
// Mega dig. pin: 29 28 27 26 25 24 23 22
// Mega port/pin: PA7 PA6 PA5 PA4 PA3 PA2 PA1 PA0 (one contiguous PORT)
// Leo dig. pin : 7 6 5 4 3 2 9 8
// Leo port/pin : PE6 PD7 PC6 PD4 PD0 PD1 PB5 PB4
// Due dig. pin : 40 39 38 37 36 35 34 33
// Due port/pin : PC8 PC7 PC6 PC5 PC4 PC3 PC2 PC1 (one contiguous PORT. -ish…)
