手把手教你使用长编码功能
- d7 D( J6 A1 Z' c; [8 y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:/ l0 H, Z; z8 ]) Z$ D

: h4 k9 ~1 w: }2 `3 U' X9 Y# X09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
9 i- d0 c5 A$ D9 `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。& ^4 T+ V c7 Y
$ y5 T5 X8 F- |3 I/ u4 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。) S: {+ [- Q! s& H0 X8 H8 P
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。: [7 I& u, x. A# D# H
. P: V9 z6 x, b! j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 t0 ^# `, V% [" T2 d$ z& 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。" Q7 _+ {1 k. M' D |. j
