Arduino LCD Screen Library

This updated library enables an Arduino board to communicate with the Arduino TFT LCD screen. It simplifies the process for drawing shapes, lines, images, and text to the screen. See also the original TFT library.

The Arduino TFT library extends the Adafruit GFX, and ILI9163 libraries that it is based on. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino GTFT. The Arduino specific additions were designed to work as similarly to the Processing API as possible.

Onboard the screen is a SD card slot, which can be used through the SD library. The TFT library relies on the SPI library for communication with the screen and SD card, and needs to be included in all sketches.

How to install

Manual Installation

Click on the "Clone or download" button in the upper right corner. Exctract the ZIP file, and move and rename the extracted folder either to the location "~/Documents/Arduino/libraries" or to your custom sketchbook folder. Create the "libraries" folder if it doesn't exist. Open Arduino IDE and the new library should show up in the libraries menu.
