This is a library for the Adafruit 1.8" SPI display.
|
|
|
|
This library works with the Adafruit 1.8" TFT Breakout w/SD card
|
|
----> http://www.adafruit.com/products/358
|
|
The 1.8" TFT shield
|
|
----> https://www.adafruit.com/product/802
|
|
The 1.44" TFT breakout
|
|
----> https://www.adafruit.com/product/2088
|
|
as well as Adafruit raw 1.8" TFT display
|
|
----> http://www.adafruit.com/products/618
|
|
|
|
Check out the links above for our tutorials and wiring diagrams
|
|
These displays use SPI to communicate, 4 or 5 pins are required to
|
|
interface (RST is optional)
|
|
Adafruit invests time and resources providing this open source code,
|
|
please support Adafruit and open-source hardware by purchasing
|
