手把手教你使用长编码功能% I4 W& c( k; X5 y; x
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:/ f( v& `3 M5 h+ H7 a G1 m
1 c; {9 K5 R3 d# g$ C/ O& n B018D8F020004100000120C000000000000087F075C, f5 M/ H4 W/ o- T1 C6 T
! u+ c6 O1 V& B c& c
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
9 j5 _+ r. p( |* o0 ?, H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。
+ y# H# P5 ^: R6 {5 u" O G. I8 o/ ?5 }- i- Q. z- e+ w4 S
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。' X- J5 Z- L* B/ y' x) e( m2 ]# w
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。
; m' P2 y* w8 {
% y0 G# C/ L4 [( ~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。( r3 j1 a% M9 R9 O
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。8 w" ~" q, i; p; {) Q
