手把手教你使用长编码功能% I, z9 |8 C& P. D
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:! v/ \( u ]5 N$ d% P" y
; N% K& ^4 ~ }3 I4 G; ]3 C018D8F020004100000120C000000000000087F075C$ C6 T$ H, `: J/ Q1 Y$ I7 n& ~
8 `" A/ o) n. k- D q" t* K
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
1 s8 j+ _3 \! Q) } `7 v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 B0 j( C3 u5 F& N+ n2 [: y
. a3 `0 J1 H* X% C4 g' R& n6 N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。# U( U6 A* ^; x! ~$ T8 X
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。) H G+ M( B" ~
9 I3 l1 Q& s, ^; z1 ]; X m7 O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。5 l# S% h- W& ?8 e6 B
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。

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。
Q+ z, r: D! ?& k, d' n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
+ W2 Y8 p o6 g7 W3 z0 x7 I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。0 J, p6 m8 ]: c5 f
这样,再把byte00合并到09功能的长编码去,原来的长编码
