树莓派 Pico W 初测

店长大人 8.5m2022-10-031800 次点击2 人感谢
8月底海购的树莓派 pico w在漂洋过海一个多月后,终于送到了。今天迫不及待地开始测试。
在网上抄了一个局域网内远程点灯的程序,感觉pico w目前除了生态不如esp外,WiFi连接速度和稳定性,都是极好的,毕竟是英飞凌的芯片,没得说。

1:此处下载pico w micropythin的SDK uf2 文件,拖入pico w 中:
https://micropython.org/download/rp2-pico-w/rp2-pico-w-latest.uf2

2: 打开Thonny,将以下代码写入,并保存至pico w,点击运行,记得修改自己的wifi信息。

3:待pico w 连接至wifi后,控制台输出pico w ip, 在浏览器地址栏中输入:
关灯
pico w ip/light/off
点灯
pico w ip/light/on


代码:
```
import network
import socket
import time

from machine import Pin

### Select the onboard LED
led = machine.Pin("LED", machine.Pin.OUT)

ssid = '你的wifi ssid'
password = '你的WiFi 密码'

"""

### Wait for connect or fail
max_wait = 10
while max_wait > 0:
if wlan.status() < 0 or wlan.status() >= 3:
break
max_wait -= 1

time.sleep(1)

### Handle connection error
if wlan.status() != 3:
raise RuntimeError('network connection failed')
else:
print('connected')
status = wlan.ifconfig()
print( 'ip = ' + status[0] )

### Open socket
addr = socket.getaddrinfo('0.0.0.0', 80)[0][-1]
s = socket.socket()
s.bind(addr)
s.listen(1)

print('listening on', addr)

### Listen for connections
while True:
try:
cl, addr = s.accept()
print('client connected from', addr)
request = cl.recv(1024)
print(request)
request = str(request)
led_on = request.find('/light/on')

print( 'led on = ' + str(led_on))
print( 'led off = ' + str(led_off))

print("led on")
led.value(1)
status = "LED is ON"

if led_off == 6:
print("led off")
led.value(0)
status = "LED is OFF"

response = html % status
cl.send('HTTP/1.0 200 OK\r\nContent-type: text/html\r\n\r\n')
cl.send(response)
cl.close()

except OSError as e:
cl.close()
print('connection closed')
