树莓派 Pico W 初测
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。
视频如下：

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'
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect(ssid, password)
html = """<!DOCTYPE html>

<meta charset="utf-8">

### Wait for connect or fail

while max_wait > 0:
if wlan.status() < 0 or wlan.status() >= 3:
break

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)

### Listen for connections
