手把手教你使用长编码功能" X& I( Q6 \: @9 Q2 T' s. t, z- ~
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 k2 G9 y: {- n! o) h: _3 `' T7 M6 i" H0 V4 e+ W4 {: `+ |
018D8F020004100000120C000000000000087F075C0 B- r8 B5 ?7 M+ [" F* s3 }
! I% K# S1 S$ O; p7 {0 l09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
4 e! u5 O2 K. ?0 G% P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。
; V: M" O+ |. O% o
) d1 A# N. Y0 W K! {: Q* G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。
9 S- o7 c6 i; N5 X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。. [2 Z4 y' F4 z# e# Z2 `3 ?
. F0 Z1 ?5 \+ K5 A& H& N: T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。
% b2 V' Z# U1 \( G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。
