手把手教你使用长编码功能3 M. }" z- _6 d9 B& G
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:
! F! q* `) m5 m) }- x9 g! b @( M* R$ E) T3 z% t
018D8F020004100000120C000000000000087F075C; Y W, ^' o5 {7 i- B0 v+ y$ V$ O
2 e1 m! y% ?, `5 w; [8 Q
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204 `& T* C; N; H7 H" Q" n
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。) q7 m" l9 V& z$ {- }+ M6 Q5 B
t+ V5 C" h% q5 k8 P" H. J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。4 ~9 s/ R/ P" C* s! Q
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。
8 W- B1 H% s6 t! f/ s* c1 D. y6 N" |# Y% W6 z0 ~/ f1 k
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。+ |% F' y9 J2 `( P+ O! b
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。4 x# G$ j0 t( c( d5 A6 u! w! w {! i

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! F' s. Y) \7 ]& c
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。, p' w% M$ a$ R2 K5 I2 m
这样,再把byte00合并到09功能的长编码去,原来的长编码
