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

// 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);

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

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