使用ESP32-S3单片机配合W5500芯片进行TCP通信,需要先确保你的硬件已经配置好,并且ESP32-S3支持网络功能。以下是一个基本的Python示例,使用Thonny作为IDE,说明如何在软件层面上编写TCP客户端或服务器:
首先,安装所需的库:
```bash
pip install machine esp32spi network
```
然后,在Thonny中创建一个新的Python文件,例如`tcp_connection.py`:
```python
import machine
from machine import Pin, SPI
from network import ESP32_SPI, TCP
# 初始化SPI和W5500
spi = SPI(sck=Pin(18), mosi=Pin(23), miso=Pin(19))
w5500 = machine.W5500(spi)
# 将ESP32-S3模式设置为Station(客户端)
if w5500.mode != ESP32_SPI.STATION:
w5500.set_mode(ESP32_SPI.STATION)
w5500.connect("your_SSID", "your_PASSWORD")
def create_server(port):
server = TCP()
server.bind(('', port))
server.listen(1) # 可以设置最大排队连接数
print(f"Server started on {port}")
while True:
client, addr = server.accept()
print(f"Accepted connection from: {addr[0]}:{addr[1]}")
client.send(b"Welcome to the server!")
client.close()
# 或者创建客户端
def create_client(ip, port):
client = TCP()
client.connect((ip, port))
client.send(b"Hello, I'm a client")
data = client.recv(100)
print(f"Received: {data.decode()}")
client.close()
# 根据需求选择启动服务器还是客户端
# create_server(8888) # 作为服务器监听8888端口
# create_client("server_ip", 8888) # 连接到指定IP的8888端口作为客户端
```
