| This tutorial is for our 1.8" diagonal TFT display & microSD breakout board. This breakout is the best way to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! | This tutorial is for our 1.8" diagonal TFT display & microSD breakout board.

Here are some of the functions we've included in the library | + | |
| The TFT LCD library is based off of the Adafruit GFX graphics core library. GFX has many ready to go functions that should help you start out with your project. Its not exhaustive and we'll try to update it if we find a really useful function. Right now it supports pixels, lines, rectangles, circles, round-rects, triangles and printing text as well as rotation. | The TFT LCD library is based off of the Adafruit GFX graphics core library.

| + | __Two__ libraries need to be downloaded and installed: first is the [[https://github.com/adafruit/Adafruit-ST7735-Library|ST7735 library]] (this contains the low-level code specific to this device), and second is the [[https://github.com/adafruit/Adafruit-GFX-Library|Adafruit GFX Library]] (which handles graphics operations common to many displays we carry). Download both ZIP files, uncompress and rename the folders to 'Adafruit_ST7735' and 'Adafruit_GFX' respectively, place them inside your Arduino libraries folder and restart the Arduino IDE. If this is all unfamiliar, we have a [[http://www.ladyada.net/library/arduino/libraries.html|tutorial introducing Arduino library concepts and installation]]. | ||
