手把手教你使用长编码功能7 P" F2 d9 O% S- F
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:
# B! s& t+ q& K4 I9 ?% S$ r3 u6 @# \! s! J: e( r
018D8F020004100000120C000000000000087F075C
; e9 r3 b, z# C2 M( T3 V
4 j5 t5 k' T5 Z7 k2 ]3 C' w09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 J0 u [+ }+ U" d, `& b+ I, V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。 Q& E" @( E$ u( [. h
! A+ u( b7 G2 M2 s' V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。
* b' f; c# [: z. x O8 [3 D$ ^4 @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。4 V8 A; [" |; k5 I0 y/ d: a
$ I3 I9 p. p& V1 k& _, o6 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。6 j6 B6 Z' M: {0 K: }
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。. ]3 i, `6 A R: E2 C

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。
