Download the Arduino IDE 及安裝系統最好是用 Windows ZIP file for non admin install

system is in ------Windows hides windows store apps in c:/users/YourUserName/AppData(hidden folder)/Local/Packages

使用的程式檔案是在 user 文件夾中的 arduino下

Arduino IDE 預設並未含有 ESP8266 開發板函式庫與驅動程式, 必須在 "檔案/偏好設定" 的 "額外的開發板管理員位址" 欄位輸入下列網址 :

http://arduino.esp8266.com/stable/package_esp8266com_index.json

然後在 "工具/開發板/開發板管理員" 中, 搜尋 "ESP8266" 會看到 "esp8266 by ESP8266 Community" 這一項, 按底下的 "安裝" 鈕進行下載安裝

安裝完成後會顯示 "Installed" :

請先固定使用3.3V 燒錄韌體時必須先將 GPIO 0 接地 , 上電之後再拔掉，即進入燒錄模式。
