/***************************************************
This is an example sketch 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
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
products from Adafruit!

// You can use any (4 or) 5 pins
#define sclk 4
#define mosi 5
#define cs 6
#define dc 7
#define rst 8 // you can also connect this to the Arduino reset
#include <Adafruit_GFX.h> // Core graphics library
#include <Adafruit_ST7735.h> // Hardware-specific library
#include <SPI.h>
// Option 1: use any pins but a little slower
Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, mosi, sclk, rst);
// Option 2: must use the hardware SPI pins
// (for UNO thats sclk = 13 and sid = 11) and pin 10 must be
// an output. This is much faster - also required if you want
// to use the microSD card (see the image drawing example)
//Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, rst);

// Our supplier changed the 1.8" display slightly after Jan 10, 2012
// so that the alignment of the TFT had to be shifted by a few pixels
// this just means the init code is slightly different. Check the
// color of the tab to see which init code to try. If the display is
// cut off or has extra 'random' pixels on the top & left, try the
// other option!
// If your TFT's plastic wrap has a Red Tab, use the following:
tft.initR(INITR_REDTAB); // initialize a ST7735R chip, red tab
// If your TFT's plastic wrap has a Green Tab, use the following:
//tft.initR(INITR_GREENTAB); // initialize a ST7735R chip, green tab
