手把手教你使用长编码功能
' I" a; b8 Q' F0 T% f h7 N% j首先我们来认识一下长编码,以09中央电器功能的长编码为例,我的原厂设置是:6 v4 c$ U+ c' }1 R1 K: n

( w9 Z7 O1 _) v3 J; V% R9 Q1 U09功能长编码是21个byte组成的,每个byte是16进制的2个字符,顺序是从左到右,从00开始到20) Q* |8 d3 }& O& L: D5 E
以上面一个为例,byte00的值就是01,byte01的值就是8D,byte02的值就是8F,以此类推到byte20就是最后一位5C。4 O7 O7 g, |: [# H
0 @% O) R3 E1 Y& l1 ?" B接下来,就是继续分解byte到bit位,我们知道,任何功能都是有开、关两种状态,在2进制中就是1、0来代表,然后,每个16进制的byte转换成2 进制就是8位bit,上面的例子中,byte00的16进制值01,转换成2进制就是00000001,byte01的16进制值8D转换成2进制就是 10001101,byte02的8F转换了就是10001111。
2 Q f- i( e6 P6 I$ a+ v有个简单的转换方法,就是利用windows系统自带的计算器,在查看选项中选择科学性计算器,然后选16进制,例如输入刚才byte01的8D,然后再点一下2进制,就会自动转换成2进制的数字。不过要记住一点,计算器转换出来的2进制,如果前面几位是0会不显示,需要我们手动补足0,例如byte00 的值01,转换成2进制,计算器上显示仍然是1,但是我们需要在前面补上7个0。
( F& f" i* a: L
$ O+ y# m- M1 ~9 d! i" V$ v+ U这样,我们就得出了byte00的值是00000001,byte01是10001101,byte02是10001111,byte03是00000010,byte04是00000000。9 ]: p6 y% z. `; Y' d
注意一下,8位的bit的前后顺序是从右向左从bit0到bit7的,也就是以byte00为例,bit0位是1,bit7位是0, byte01的bit0位是1,bit1位是0,bit2位是1,和byte的顺序正好相反,这一点一开始很容易搞错,千万注意,呵呵。

得到了上述的编码后,然后我们再来看09长编码的功能对照表。, S1 M7 a8 a8 f" q5 g

上面截取了byte00-byte04的功能对照,对比上面的代码,我们很容易看出,byte00位除了只有bit0是1,即打开状态,对应的功能是 Fog Lights installed (PR-8WB)即安装了雾灯,byte01位的bit0 bit2 bit3 bit7是打开状态,对应的功能是Rear Seat Recognition installed,Electronic Fuelpump Relay installed (Gasonline only),Rear Wiper installed,Rear Wiper with Front Wiper continiously active。' O1 b3 T+ |& F2 K5 h5 s
