# ILI9341 TFT Display

> Full color 240x320 2.8" LCD-TFT display with SPI interface

Full color 240x320 2.8" LCD-TFT display with SPI interface

## Pin names

<ParamField path="VCC" type="pin">
  Supply voltage
</ParamField>

<ParamField path="GND" type="pin">
  Ground
</ParamField>

<ParamField path="CS" type="pin">
  Chip select
</ParamField>

<ParamField path="RST" type="pin">
  Reset (not available in simulation)
</ParamField>

<ParamField path="D/C" type="pin">
  Data/command pin
</ParamField>

<ParamField path="MOSI" type="pin">
  SPI data (MCU → LCD)
</ParamField>

<ParamField path="SCK" type="pin">
  SPI clock
</ParamField>

<ParamField path="LED" type="pin">
  Backlight LED (not available in simulation)
</ParamField>

<ParamField path="MISO" type="pin">
  SPI data (LCD → MCU) - optional unless reading data back from LCD
</ParamField>

<Note>
  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.
</Note>

## Attributes

<ParamField path="flipHorizontal" type="string" default="">
  Set to "1" to flip the display horizontally
</ParamField>

<ParamField path="flipVertical" type="string" default="">
  Set to "1" to flip the display vertically
</ParamField>

<ParamField path="swapXY" type="string" default="">
  Set to "1" to change the orientation of the display (some LCD panels have the X/Y axes swapped)
</ParamField>

## 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*:

```cpp theme={null}
#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() { }
```
