  tft.begin();
  tft.fillScreen(BLACK);
  tft.setTextColor(WHITE);
  tft.setTextSize(2);
  tft.setCursor(10, 10);
  tft.println("Hello, World!");
}

void loop() {
  // Nothing to do here, the text is displayed in the setup function
}
```

TFT tft = TFT(TFT_CS, TFT_RST);

void setup() {
  tft.begin();
  tft.fillScreen(BLACK);
  tft.fillCircle(120, 120, 50, RED);
}

void loop() {
  // Nothing to do here, the graphic is displayed in the setup function
}
```
### Example 3: Displaying Sensor Data (Temperature)

In this example, we will display the temperature data from a DS18B20 temperature sensor on the TFT display.
```c++
#include <TFT.h>
#include <DallasTemperature.h>

#define TFT_RST  4 // Reset pin of the display
#define TFT_CS  10 // Chip select pin of the display
#define TEMP_PIN 2 // Pin for the DS18B20 temperature sensor

TFT tft = TFT(TFT_CS, TFT_RST);
DallasTemperature tempSensor(TEMP_PIN);

void setup() {
  tft.begin();
  tft.fillScreen(BLACK);
  tft.setTextColor(WHITE);
  tft.setTextSize(2);

void loop() {
  tempSensor.requestTemperatures();
  float temperature = tempSensor.getTempCByIndex(0);
  tft.setCursor(10, 10);
  tft.print("Temperature: ");
  tft.print(temperature);
