手把手教你使用长编码功能
7 u- }: j! K9 k1 o* z$ a6 \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:4 I+ C1 h9 Q" B" p& V, i
6 u+ T. t+ p% U& e+ _2 \018D8F020004100000120C000000000000087F075C
. q0 U' |. N% A$ `% p8 E5 U) w: N8 [$ g% o3 p
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- p g. Y S- x# n4 k% z' z
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。
3 b% D8 p( ?3 m# k7 I0 L D* {7 e2 d$ V. x0 m: ?: D
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。# y4 G, f/ {, _ J1 B3 X9 `
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。
! ]5 y0 w* {7 p. U- U2 j* L; o& X5 ?+ L! s
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。
( S0 d- d8 l& Q: d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。. \: I& K6 N, v

得到了上述的编码后,然后我们再来看09长编码的功能对照表。 M3 Q9 A9 p/ h& {. W& a7 \

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。. r1 F7 m' o' s0 J- v. [
