手把手教你使用长编码功能( e# f0 c& G" J/ k( 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:6 v. z+ C$ x& D q' h5 @9 m
X' S/ c' J1 U4 c! h018D8F020004100000120C000000000000087F075C
- P# @' L2 _' R6 E2 }
' F4 ^1 y8 Q K( p4 E( c8 n: z09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' g) D! z7 x& H( a8 t6 E1 @; w2 M s; T3 k
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。
) s' K- Y7 ?# f2 V' f. m" S1 n$ @& F! K9 k" A( @: F
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。
) g1 R2 s. k0 Y+ b, w/ v+ X: 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。% R# Z* p9 d. Q2 m
" c$ |4 C; n5 [6 ?! E* E
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 q; v/ l) |1 y6 _) `! Y' }# t
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。
