Software ( Arduino Library )



Arduino GLCD Library Version3 ( or AVR Controller )

Download https://code.google.com/p/glcd-arduino/downloads/list



GLCD-Arduino has the following features:
  • Support for Arduino 1.x (still works with pre 1.x IDEs)
  • Support for Mega 2560, Sanguino and Teensy boards
  • Easier pin assignment. Any pin can be assigned to any glcd function.
  • Accurate/Consistent font rendering of any font size on any pixel location.
  • User definable text areas
  • Up/Down text scrolling
  • Circle functions
  • Additional example and demo sketches including a diagnostic sketch
  • Fully search-able documentation in HTML format
  • Pins can optionally be assigned by AVR port and bit instead of Arduino pin number.
  • Supports fixed width fonts that provides up to 8 x 21 character display with the supplied system font.
  • CursorTo method to position the cursor to a given font location (fixed width fonts only)
  • DrawBitmap function to display bitmap images stored in Flash memory. A Processing utility is provided in the download to convert a monochrome bitmap file to a header file that stores the image in flash for use by the DrwBitmap method.


Create Font  use GLCD Font Creator 2
Use this program https://code.google.com/p/glcd-arduino/downloads/detail?name=GLCDFontCreator2.zip



How to Create Font in other Language


FONT 8 x 8

FONT 14 x 20


Example in Thai language
I've edit GLCD Font Creator 2 for Thai language only. ( Java Code )

Arduino and TFT LCD Display Module



Arduino TFT LCD Display Module Test

Hardware
1.Arduino UNO Board or Compatible
2.TFT LCD 2.2 inch  from Elecfreaks ( Model  TFT01-2.2SP )
http://www.elecfreaks.com/store/22%E2%80%99-tft-lcd-tft0122sp-p-672.html


Description:

TFT LCD module has always been one of the hot products in DIY industry and LCD is basically the necessary products during all projects, at the same time, serial port modules are also the popular ones, because it takes few IO and the usage is simple. This section of the 2.2S-inch TFT LCD serial SPI integrated features of compact, SPI interface, fully compatible with popular LCD5110 interface cable sequence, and will replace the increasingly reducing LCD5110.

Feature:

TFT01_2.2 SP is a 2.2 "SPI TFT LCD Screen Module, 10pins interface, compatible LCD5110 interface. Not just a LCD break but include SD card (2GB),
The LCD in the TFT01 is ILI9341. It's a 240 * 320 (resolution), 2.2S inch TFT LCD screen.The LCD has a wide viewing angle, the contrast is also very suitable.

The display interface is serial, it just needs 5 wires (CS, RS, SCL, SDA, RST) for controlling.
Replace LCD5110, Support direct plug in ElecFreaks Joystick shield, EFCom, Key Pad Shield etc
SDcard use hardware SPI interface (CS / MOSI / MISO / SCK), Not solder pins.
Parameter:

SDO: Serial clock output
LED: 3.3V IO and Power Supply pin
SCL: Serial clock input
SDA / SDI: Serial data input
DC: Data / Command selection
RST: Reset, Low level active
CS: Chip Selection, Low level active
GND: Ground
VDD33: 3.3V Power Supply pin
UTFT Support

Software

Driver UTFT Library  by Henning Karlsen
http://henningkarlsen.com/electronics/library.php?id=52

his library is the continuation of my ITDB02_Graph, ITDB02_Graph16 and RGB_GLCD libraries for Arduino and chipKit. As the number of supported display modules and controllers started to increase I felt it was time to make a single, universal library as it will be much easier to maintain in the future.
