手把手教你使用长编码功能3 k( g! C# ~- v2 C: W8 w
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:9 [8 j+ {+ {3 ]1 ?3 Y; x
& U. m' _1 n4 B7 ~6 `0 j+ f018D8F020004100000120C000000000000087F075C0 ?1 c; s$ i, w( d
5 V* Y3 K" g1 w) u1 X
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
5 e5 z o$ s- G N3 X c/ @- l r- {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。$ D( J, H: I9 j
/ y1 M( W0 {& d, p# X0 K0 G% Y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。# o4 V( G( `% Z: }
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。
2 D4 V6 g' E7 v/ m% D8 ?: l( R+ S
: ?4 a( k! ?% L; I: M- p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。
- `4 z: @; H1 r3 ?. I F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。2 r2 u0 x0 h7 |6 p' A6 X$ V, S

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10100011- Y2 o6 W y& D( R* P8 f
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。" a- o* o" E5 K" ?1 B5 B0 [. y
