手把手教你使用长编码功能- @1 s, O" A$ W" q" M" q' A0 m3 O
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:8 e( q0 ?# i- F) L, ~( e
4 y& N+ W" V N; D* e8 T( v2 T
018D8F020004100000120C000000000000087F075C
5 A9 `) a2 L2 Q+ Z' z
& S# _! d! i7 g, g5 I09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- W' s* m& E! @
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。0 T+ L2 |6 u- O4 P
9 o! F) L3 g% X) 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。
& P: W: l; ]6 y) m) T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。
' l+ @4 u, ~6 C d7 ^4 i; Z4 \0 G$ ]; U& v* j+ R7 C7 K6 w% W7 _6 R
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。8 t. c; j8 l# R+ I3 x
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。' J' W! V& N" i4 L7 g1 C

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。; ?" u9 x) N8 w/ R2 ?3 y
