How to use it?
1. use 5v to led pin, 3.3v to vcc and 1k / 1.5k resistor voltage dividers to get it to work. 1k resistor in series from Arduino to tft logic pin, 1.5k from tft pin to ground.
2.#define TFT_DC 9
#define TFT_CS 10
#define TFT_MOSI 11
#define TFT_CLK 13
#define TFT_RST 12
#define TFT_MISO 8
3.// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
//ILI9341 tft = ILI9341(TFT_CS, TFT_DC);
4.// If using the breakout, change pins as desired
ILI9341 tft = ILI9341(TFT_CS, TFT_DC, TFT_MOSI, TFT_CLK, TFT_RST, TFT_MISO).
