手把手教你使用长编码功能
& f: j' F! G; R8 y3 Q8 l7 U/ _" P: s% a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) s* n, t3 o: f+ |
( a" s- I6 J$ j018D8F020004100000120C000000000000087F075C
- ]+ \& S. n6 m: S+ F
1 K/ J+ r* K3 ~3 P) T" B- H09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
* R; W3 l6 r5 y& ]% d. d) 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。/ k" I' Q& g4 p- x/ E
( \9 V; W$ l1 I# u& r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。
* E7 I& O/ B- ?# o( E/ C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。# K# k: d Z& @% U6 K! M8 q
, S, f6 } D, }: S! H* o3 W; }
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 ?' O/ J% z# i. F$ d3 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。& S! O3 P, K0 R( f$ m

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。3 j) M6 L: c3 @8 W) q( A( r, g
