格力空调遥控器红外编码透析

格力空调遥控器（YB0F2）红外码组成如下，按解码顺序排列 

起始码（S）+35位数据码+连接码（C）+32位数据码 

1、各种编码的电平宽度： 

数据码由“0”“1”组成： 

0的电平宽度为：600us低电平+600us高电平，

1的电平宽度为：600us低电平+1600us高电平

起始码S电平宽度为：9000us低电平+4500us高电平

连接码C电平宽度为：600us低电平+20000us高电平

 2、数据码的形成机制 

前35位数据码形成如下图所示：

后32位数据码形成如下图所示：

上表中，大于两位的数据都是逆序递增的，各数据的意义如下：

校验码的形成机制如下：

校验码= [(模式– 1) + (温度– 16) + 5 +左右扫风+换气+节能]取二进

制后四位，再逆序；

例如：如果需要设置一下的状态，模式4，30℃，左右扫风，换气关闭，节能关闭，那么校验码为：

(4 – 1)+(30-16)+5+1+0+0 = 15,取低四位为0111，逆序后为1110 

 

注意：为了方便编码，在编码时可以正序，解码端再逆序，解码的时候先解码低字节，再解码高字节的位。

另外定时数据对最后的校验码的影响没有测试，因为很少会用到这个功能。
