手把手教你使用长编码功能" V* J9 X* { T) L
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:! ^* k8 w8 k' o

) I6 i9 D( r4 _4 x$ N, L( u& g
5 |6 P# {' V! s8 h* p& |6 N09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
2 e6 c3 C! \* K. Q7 ?3 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。8 {8 @( o. S7 p2 @( O, B5 Z
8 T1 O |7 n, Q" F3 ^2 d) ?6 {2 a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。
1 O0 u% A- q, @* Z2 D; 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。
# E9 ?% A% I+ H7 [( O. Q+ {3 V2 y
% Q1 v9 ~* C" O% p9 v: G! @7 [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。
2 y9 F; X8 H! ]6 c2 p6 M7 N4 V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。

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。
