Adafruit_ST7735.h

00001 /***************************************************
00002   This is a library for the Adafruit 1.8" SPI display.
00003   This library works with the Adafruit 1.8" TFT Breakout w/SD card
00004   ----> http://www.adafruit.com/products/358
00005   as well as Adafruit raw 1.8" TFT display
00006   ----> http://www.adafruit.com/products/618
00007  
00008   Check out the links above for our tutorials and wiring diagrams
00009   These displays use SPI to communicate, 4 or 5 pins are required to
00010   interface (RST is optional)
00011   Adafruit invests time and resources providing this open source code,
00012   please support Adafruit and open-source hardware by purchasing
00013   products from Adafruit!
