2.8 Inch TFT LCD Shield Touch Display Screen Module For Arduino

I recently started looking through various shields I had no articles, code or tutorials for and came across a 2.8 Inch TFT LCD Shield Touch Display Screen Module For Arduino

Its a cracking display, here are some pictures of it

Features:

2.8 inch LCD TFT display
Bright, 4 white-LED backlight
Colorful, 18-bit 262,000 different shades
4-wire resistive touchscreen 240 x 320 pixels with individual pixel control
No wiring, no soldering.
Simply plug it in and load library
On-board 3.3V 300mA LDO regulator
5V compatible, use with 3.3V or 5V logic
Support 2GB micro SD TF card
Size: 7.8 x 5.3cm

Parts List

Code

I connected the shield to an Arduino Mega

4 libraries are required with the code example that I tested with – I uploaded these to my github site

[codesyntax lang=”cpp” lines=”fancy”]

// 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.
//Technical support:goodtft@163.com

#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
#define CYAN    0x07FF
#define MAGENTA 0xF81F
#define YELLOW  0xFFE0
#define WHITE   0xFFFF

#include <MCUFRIEND_kbv.h>
MCUFRIEND_kbv tft;
// If using the shield, all control and data lines are fixed, and
// a simpler declaration can optionally be used:
// Adafruit_TFTLCD tft;
