Code Examples

The following examples demonstrate how to use the Elecrow CrowPi2 with Raspberry Pi 4 in various contexts:

Example 1: Basic Keyboard and Display Usage

This example showcases the use of the CrowPi2's keyboard and display with a Raspberry Pi 4.

Language: Python 3

Code:
```python
import tkinter as tk

# Initialize the tkinter GUI
root = tk.Tk()

# Create a simple label and button
label = tk.Label(root, text="Hello, World!")
label.pack()
button = tk.Button(root, text="Click me!", command=lambda: print("Button clicked!"))
button.pack()

# Start the GUI event loop
root.mainloop()
```
Explanation:

This code creates a simple GUI using the tkinter library, which is bundled with the Raspberry Pi OS. The GUI includes a label and a button. When the button is clicked, a message is printed to the console. This example demonstrates the use of the CrowPi2's keyboard and display with a Raspberry Pi 4.

Example 2: IoT Project with Wi-Fi Connectivity

This example demonstrates the use of the CrowPi2's Wi-Fi connectivity feature with a Raspberry Pi 4 to create a simple IoT project.

Language: Python 3

Code:
```python
import socket
import wifi

# Connect to a Wi-Fi network
wifi.connect('your_wifi_ssid', 'your_wifi_password')

# Create a socket object
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Bind the socket to a address and port
server_address = ('0.0.0.0', 8080)
sock.bind(server_address)

# Listen for incoming connections
sock.listen(1)

print("Server started. Waiting for connections...")

while True:
    # Accept incoming connections
    connection, address = sock.accept()
    print("Connected by", address)

# Receive and send data
    data = connection.recv(1024)
    if data:
        print("Received data:", data.decode())
        connection.sendall(data)
    else:
        print("No data received")
        break

# Close the connection
    connection.close()
```
Explanation:

This code creates a simple Wi-Fi server using the socket library, which allows the Raspberry Pi 4 to connect to a Wi-Fi network and listen for incoming connections. When a connection is established, the server receives and sends data to the client. This example demonstrates the use of the CrowPi2's Wi-Fi connectivity feature with a Raspberry Pi 4 in an IoT project.
