海爾空調遙控YR-M10解碼測試

家裏好幾個海爾空調，遙控器如下。它們協議並不相同，所以空調之間有的功能部分相通，有的完全不通。其中有一個YR-M13看起來跟淘來的YR-M10相似，但是很不幸。協議也是不一樣的。

 

看了前輩寫的貼

1、解讀海爾壁掛空調紅外遙控編碼之我見,有源碼啊！http://bbs.mydigit.cn/read.php?tid=1152024

2、海爾空調遙控編碼分析http://bbs.mydigit.cn/read.php?tid=2637581

 

Luckily，第一篇講的就是YR-M10的協議講解。細緻入微。打印下來依次驗證

 

寫個解碼的類
