Pin names

VCC · pin

Supply voltage

GND · pin

Ground

CS · pin

Chip select

RST · pin

Reset (not available in simulation)

D/C · pin

Data/command pin

MOSI · pin

SPI data (MCU → LCD)

SCK · pin

SPI clock

LED · pin

Backlight LED (not available in simulation)

MISO · pin

SPI data (LCD → MCU) - optional unless reading data back from LCD

The RST and backlight (LED) pins are not available in the simulation. You can leave MISO disconnected, unless you need to read data back from the LCD.

Attributes

flipHorizontal · string · default: ""

Set to “1” to flip the display horizontally

flipVertical · string · default: ""

Set to “1” to flip the display vertically

swapXY · string · default: ""

Set to “1” to change the orientation of the display (some LCD panels have the X/Y axes swapped)

Using in Arduino

You can use the Adafruit_ILI9341 library or the lcdgfx library to interface with the LCD display. The following code example shows basic usage with Adafruit_ILI9341:

#include "SPI.h"
#include "Adafruit_GFX.h"
#include "Adafruit_ILI9341.h"

#define TFT_DC 9
#define TFT_CS 10
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);

void setup() {
  tft.begin();

  tft.setCursor(26, 120);
  tft.setTextColor(ILI9341_RED);
  tft.setTextSize(3);
  tft.println("Hello, TFT!");

  tft.setCursor(20, 160);
  tft.setTextColor(ILI9341_GREEN);
  tft.setTextSize(2);
  tft.println("I can has colors?");
}

void loop() { }
