| 2 | This is a library for the Adafruit 1.8" SPI display.
|
---|
| 3 | This library works with the Adafruit 1.8" TFT Breakout w/SD card
|
---|
| 4 | ----> http://www.adafruit.com/products/358
|
---|
| 5 | as well as Adafruit raw 1.8" TFT display

|
---|

|
---|
| 8 | Check out the links above for our tutorials and wiring diagrams
|
---|
| 9 | These displays use SPI to communicate, 4 or 5 pins are required to
|
---|
| 10 | interface (RST is optional)
|
---|
| 11 | Adafruit invests time and resources providing this open source code,
|
---|
| 12 | please support Adafruit and open-source hardware by purchasing
|
---|
| 13 | products from Adafruit!
