手把手教你使用长编码功能
p* w, r% F/ w( 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:
s5 @# F& k9 U! k
' c4 f* s# |5 c018D8F020004100000120C000000000000087F075C
8 K. t/ o/ o( a. v# T8 t
% w* b* m5 B8 R( G# k3 I/ D09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$ F4 V7 w3 _" s; s, H4 Z: f. P9 q
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; e. s5 r1 a3 y, I
; K X, l9 o8 Q" v3 q6 z2 H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。
) x3 _2 ^0 b8 H1 | j1 K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。
3 [& o, C$ Y7 j( U+ I
) B% D7 q7 i1 j) C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。
$ w2 D8 x3 J! x0 s4 u6 |, 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。

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101000116 {* c6 T$ u' m
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。( _/ h, a. l" }# r( [& w
