手把手教你使用长编码功能
4 ]. f6 q: Y+ ~. R- C: r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:
+ {: ~! Y* p+ d: r( A
9 o* _" l' C- p, s018D8F020004100000120C000000000000087F075C Q/ I/ l. K+ ?2 Z. ^
6 O6 P/ j' \" ]4 N09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
) D1 L8 L; J' S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。
7 T! x; I5 T* c8 k3 k5 }2 C: f; u) H# G" i* {9 O
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。
9 e' X, d8 W4 G1 W5 ]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。
E% q$ i9 M7 ]6 }
6 q& y" s/ [0 P5 Q- d. y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 l( y ?+ K2 _8 |( z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。$ F* [0 }$ M. I3 {

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。

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。# D.

接下来,我们再找到我们需要变更的功能,比如说我们需要调节氙灯模式,那么对应功能表中是

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10100011
( y; M4 c! h: X; H8 w$ x7 t6 x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。
