MT7688: Web Request 控制亮燈

MT7688 Python 發送 Web Client 請求，並且控制亮燈:
建議先將 MT7688 連接至 Client 模式，才好發送 Web Request。

Web.py 如下:

import mraa
import time
import urllib2

gpio = mraa.Gpio(21)
gpio.dir(mraa.DIR_OUT)

content = urllib2.urlopen("http://192.168.100.1").read()

print(content)

if content is not None:
    while True:
        gpio.write(1)
        time.sleep(0.5)
        gpio.write(0)
        time.sleep(0.5)
else:
    gpio.write(1)

執行時為了避免終端機卡死，所以在指令後面加一個 &:
