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

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

  1. // IMPORTANT: Adafruit_TFTLCD LIBRARY MUST BE SPECIFICALLY
  2. // CONFIGURED FOR EITHER THE TFT SHIELD OR THE BREAKOUT BOARD.
  3. // SEE RELEVANT COMMENTS IN Adafruit_TFTLCD.h FOR SETUP.
  4. //Technical support:goodtft@163.com
  5.  
  6. #include <Adafruit_GFX.h> // Core graphics library
  7. #include <Adafruit_TFTLCD.h> // Hardware-specific library
  8.  
  9. // The control pins for the LCD can be assigned to any digital or
  10. // analog pins...but we'll use the analog pins as this allows us to
  11. // double up the pins with the touch screen (see the TFT paint example).
  12. #define LCD_CS A3 // Chip Select goes to Analog 3
  13. #define LCD_CD A2 // Command/Data goes to Analog 2
  14. #define LCD_WR A1 // LCD Write goes to Analog 1
  15. #define LCD_RD A0 // LCD Read goes to Analog 0
  16.  
  17. #define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin
  18.  
  19. // When using the BREAKOUT BOARD only, use these 8 data lines to the LCD:
  20. // For the Arduino Uno, Duemilanove, Diecimila, etc.:
  21. // D0 connects to digital pin 8 (Notice these are
  22. // D1 connects to digital pin 9 NOT in order!)
  23. // D2 connects to digital pin 2
  24. // D3 connects to digital pin 3
  25. // D4 connects to digital pin 4
  26. // D5 connects to digital pin 5
  27. // D6 connects to digital pin 6
  28. // D7 connects to digital pin 7
  29. // For the Arduino Mega, use digital pins 22 through 29
  30. // (on the 2-row header at the end of the board).
  31.  
  32. // Assign human-readable names to some common 16-bit color values:
  33. #define BLACK 0x0000
  34. #define BLUE 0x001F
  35. #define RED 0xF800
  36. #define GREEN 0x07E0
  37. #define CYAN 0x07FF
  38. #define MAGENTA 0xF81F
  39. #define YELLOW 0xFFE0
  40. #define WHITE 0xFFFF
  41.  
  42. #include <MCUFRIEND_kbv.h>
  43. MCUFRIEND_kbv tft;
  44. // If using the shield, all control and data lines are fixed, and
  45. // a simpler declaration can optionally be used:
  46. // Adafruit_TFTLCD tft;
