Code Examples

### Example 1: Displaying a Static Image

This example demonstrates how to display a static image on the 2.4inch Raspberry Pi Display Hat using Python and the `PIL` (Python Imaging Library).

dependencies:

`PIL` (Python Imaging Library)

code:
```python
import os
import PIL.Image as Image
from PIL import ImageDraw, ImageFont

# Initialize the display
disp = pygame.display.set_mode((320, 240))

# Load the image
image = Image.open('image.bmp')

# Display the image on the screen
disp.blit(image, (0, 0))
pygame.display.update()
```
In this example, we load a BMP image using the `PIL` library and display it on the screen using the `pygame` library.

### Example 2: Displaying Real-Time Sensor Data

This example demonstrates how to display real-time sensor data on the 2.4inch Raspberry Pi Display Hat using Python and the `RPi.GPIO` library.

dependencies:

`RPi.GPIO`
 ` Adafruit_CharLCD` (for the LCD display)

code:
```python
import RPi.GPIO as GPIO
from Adafruit_CharLCD import Adafruit_CharLCD

# Initialize the GPIO pins
GPIO.setmode(GPIO.BCM)

# Initialize the LCD display
lcd = Adafruit_CharLCD(rs=26, en=19, d4=13, d5=6, d6=5, d7=11,
                         cols=20, lines=4)

# Read temperature data from a DS18B20 sensor
temp_sensor = DS18B20('28-000007751dff')
temperature = temp_sensor.get_temperature()

# Display the temperature data on the LCD display
lcd.message('Temperature: {:.1f}C'.format(temperature))

# Update the display every second
while True:
    lcd.message('Temperature: {:.1f}C'.format(temp_sensor.get_temperature()))
    time.sleep(1)
```
In this example, we read temperature data from a DS18B20 sensor using the `RPi.GPIO` library and display it on the LCD display using the `Adafruit_CharLCD` library. The temperature data is updated every second.

Note: These code examples are just a starting point, and you may need to modify them to suit your specific project requirements. Additionally, you may need to install additional libraries and dependencies depending on your project's requirements.
