手把手教你使用长编码功能. Q7 v8 G/ N, Z! Y& `6 L5 m' {
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:/ S: [5 I5 R4 j

$ b3 e8 a( L: R( `09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& y F: u& P" u# L! E% I5 c
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。
( S1 G C4 v3 L( Y+ f2 a
# N5 Y, ^, b; K2 L( M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。
7 R# Y# `8 u d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。
$ y8 I C4 q3 R; h3 m9 X9 g4 a' S2 W. z8 L. x9 Q7 | B; J# \4 |
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 O: B5 r1 t7 c/ ~8 T3 \2 s* X6 T! E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。

9 j& z# S; d9 u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。

那么我们只需要把byte00的bit1 bit5 bit7位由0变成1,这样原来的byte00位00000001就变成了101000110 z L0 B! W2 S; P
然后我们再用windows的计算器程序把2进制变为16进制,转换回去的byte00的16进制编码就是A3。
& _( N1 }& e, l/ v. B这样,再把byte00合并到09功能的长编码去,原来的长编码; g" v6 X; i( m" j% O
