pyautotest-pycharm配置python环境
ESP32是一种基于Espressif Systems的开源硬件平台,常用于物联网(IoT)应用,尤其是Wi-Fi连接。它通常通过MicroPython等嵌入式Python环境工作。而PyCharm是一款流行的集成开发环境(IDE),主要用于Python编程。
**在ESP32上编写Python(MicroPython)端程序**:
```python
import usocket as socket
from machine import Pin
# 创建一个UDP套接字
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
# ESP32的UDP服务器地址和端口
server_ip = '0.0.0.0'
server_port = 8888
# 创建一个数据发送pin
led_pin = Pin(2, Pin.OUT)
while True:
# 等待数据接收
data, addr = s.recvfrom(64)
# 解码接收到的数据
command = data.decode()
if command == "ON":
led_pin.on()
print("LED turned ON")
elif command == "OFF":
led_pin.off()
print("LED turned OFF")
else:
print("Invalid command")
```
在这个程序中,ESP32作为服务器监听来自PyCharm或其他客户端的消息,并根据接收到的命令控制LED灯。
**在PyCharm上编写Python客户端程序**(假设使用`asyncio`库):
```python
import asyncio
import websockets
async def send_command(websocket_url):
async with websockets.connect(websocket_url) as websocket:
await websocket.send("ON") # 发送"ON"指令到ESP32
print("Command sent: ON")
await websocket.send("OFF") # 发送"OFF"指令
print("Command sent: OFF")
async def main():
uri = f"ws://{ESP32_IP}:{ESP32_PORT}"
await send_command(uri)
loop = asyncio.get_event_loop()
try:
loop.run_until_complete(main())
except KeyboardInterrupt:
pass
finally:
loop.close()
```
这里假设`ESP32_IP`和`ESP32_PORT`是你ESP32设备的实际IP地址和端口号。
