Micropython環境布置
(1)安裝CP2012Driver
  1.接好ESP8266  usbt8插電腦
  2.控制台->系統->裝置管理員->連接埠(COM3)
(2)使用ESP8266Flasher燒錄Micropython韌體
確定有bin檔
1.執行ESP8266Flasher
operation  COM3
2.config 確定bin檔位置  不能有中文目錄最好放在c
3.advance確定值
4.回operation 按下flasher
5.log 成功否
   拔下usb再插上

(3)使用putty測試韌體是否燒錄成功
1.serial2.COM3 1152003.mp8266 ->save->load->open

(4)安裝Micropython編輯器
upycraft-master3放在c
(5)撰寫Micropython程式測試

網路通訊
1.函數庫
import network

2.呼叫network模組
network,WLAN()函數
(a)network.STA_IF 混合型
(b)network.AP_IF
sta=network.WLAN(network.STA_IF)
ap=network.WLAN(network.AP_IF)
MCU--wifi(STA_IF)~~internet~~web

3.呼叫介面物件
sta.active() 檢查是否啟動
sta.active(boolean)  true為啟動　false關閉

4.掃描附近基地台
sta.scan()

5.連線
sta.connect("帳號","密碼")

6.顯示基本組態
sta.ifconfig()


測試通否
import network

sta_if.active(True)
sta_if=network.WLAN(network.STA_IF)
print(sta_if.active())

True
====================

import network

sta_if=network.WLAN(network.STA_IF)
print(sta_if.active())
print(sta_if.ifconfig())
-------------------------
False
('0.0.0.0', '0.0.0.0', '0.0.0.0', '192.168.0.1')
-----------------------------------
ap_if同樣測試
-----------------------------------
import network

sta_if.active(True)
sta_if=network.WLAN(network.STA_IF)

sta_if.connect('bsnet-1','062230542')
print(sta_if.ifconfig())
---------------------------
exec(open('wifi5.py').read(),globals())
('192.168.0.118', '255.255.255.0', '192.168.0.1', '192.168.0.1')
確定能連
-----------------------------------
建立socket
1.引入socket函數庫
inport socket
   標準socket API
2.元件
s=socket.socket()
3.建立socket位址和埠端
getaddinfo("0.0.0.0",8080)
                  或IPV6位址
ai[0][-1]---取得IP位址

4.設定套件選項的值
setsocketopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)

5.將套件函數綁定在位址上
bind(addr)

6.開放監聽TCP傳入連接
listen(5)
一次開五個監聽

接收傳送資料
1.等候連線，接收網路封包資料
res=socket.accept()  傳回串列
client_s=res[0]   客戶端物件[封包內容]
client_addr=res[1] 位址

2.接收TCP資料
req=client_s.recv(4096)  放緩衝器的容量

3.發送web HMI內容
client_s.send(data)       webDMI

4.關閉連線
client_s.close()
