ESP8266美的空调红外控制库(Arduino)

有关美的空调的ESP8266的红外控制库，适用于Arduino平台，需配合IRremoteESP8266库使用。

文件基于IRremoteESP8266库文件编写。

具体代码请访问https://github.com/GYSS1204/IRsendMeidi_ESP8266-RN02S-Midea

对Arduino中IRremoteESP8266库美的空调控制的补充，主要依赖于IRremoteESP8266库的sendData()函数来实现数据的发送。

需配合Arduino中的IRremoteESP8266库使用。

主要控制采取的实际数据来源于美的空调RN02S13遥控器，空调型号为美的冷静星。

可以控制的参数：温度（精确到0.5），模式，风速，开关机，定时，扫风，ECO，防直吹。

文件为库文件，直接将文件夹IRsendMeidi放入ArduinoIDE的库文件夹中即可。

参数设置

• 温度设置，17-30，分辨率0.5
• 设置模式，0自动，1制冷，2制热，3抽湿，4送风
• 设置风速，0自动，1为20%，2为40%，3为60%，4为80%，5为100%
• ECO，扫风，防直吹，参数1为打开，参数0为关闭。

使用逻辑分析仪采集到的数据

因编程水平不高，代码有写的不好的地方，不喜勿喷。

所有数据都是我使用逻辑分析仪从遥控器上面采集的，并且手动把二进制转换成十六进制，难免会有出现错误的情况，若遇到问题，请反馈给我。
