// OPTION 1 (recommended) is to use the HARDWARE SPI pins, which are unique

// to each board and not reassignable. For Arduino Uno: MOSI = pin 11 and

// SCLK = pin 13. This is the fastest mode of operation and is required if

// using the breakout board's microSD card.

// For 1.44" and 1.8" TFT with ST7735 use:

Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);

// For 1.14", 1.3", 1.54", and 2.0" TFT with ST7789:

//Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_RST);

// OPTION 2 lets you interface the display using ANY TWO or THREE PINS,

// tradeoff being that performance is not as fast as hardware SPI above.

//#define TFT_MOSI 11  // Data out

//#define TFT_SCLK 13  // Clock out

// For ST7735-based displays, we will use this call

//Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);
