Arduino TFT LCD Screen

The Arduino TFT screen is a backlit LCD screen with headers. You can draw text, images, and shapes to the screen using the TFT library. There is an onboard micro-SD card slot on the back of the screen that can store bitmap images for display.

The screen's headers are designed to fit into the socket on the front of the Arduino Esplora, but it is compatible with any AVR-based Arduino (Uno, Leonardo, etc.) or with the Arduino Due. To connect the screen to other Arduino boards, refer to the tutorial.

The screen measures 1.77 inches diagonally, with a resolution of 160 x 128 pixels. The TFT library interfaces with the screen's controller through SPI. Refer to the screen's data sheet for complete details.

The screen operates on +5 VDC.

The micro-SD slot is accessible through the SD card library.

The LED backlight is dimmable by PWM.

The screen's headers are arranged for easy connection to the Arduino Esplora and Arduino Robot.

The Arduino TFT library extends the Adafruit GFX and Adafruit ST7735 libraries. The GFX library handles the drawing routines, while the ST7735 library is specific to the screen. The Arduino-specific additions were designed to work similarly to the Processing API.

The library is backwards compatible, allowing the use of Adafruit functions.

The TFT library relies on the SPI library, which must be included in any sketch that uses the screen. If you wish to use the SD card, you need to include the SD library as well.
