手把手教你使用长编码功能
, ]7 u* z) P" S/ 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:$ W. \. c( p" P o/ Z# c# _
: i5 {& n% Y* |* R- H018D8F020004100000120C000000000000087F075C
+ U, _" |# \8 n4 [3 b: [
: _( |, K- B7 {1 `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202 p |8 ]2 Q/ a3 V! J
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。
! d2 _ g& W, E r5 R* D* _0 b
' W/ x/ H; \0 `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。
c* b6 N, K0 H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。
) Y" A Z! T, v8 @5 Z: A) n$ r6 v. ~3 V3 ~/ q- M1 E
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。 U. S# a0 G a% x! V
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。) y( D9 L$ T' S2 x

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。" X) g% i% t) Q. g; }+ }: B) c1 C

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, w. N& o3 w$ w6 K8 u& L5 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。5 o+ `0 B5 n% L2 P
