手把手教你使用长编码功能
# T9 a* S& ]" g4 P* a1 A! O; U0 }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:
* ~( } |; ]+ h5 X+ q8 G# k* x5 z7 P' ~: N( s2 ~
018D8F020004100000120C000000000000087F075C* P; y/ d- O" h/ _( q
: T3 t9 J- C3 Z9 _6 c+ E& }; [0 O09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) H6 o0 S% Y: x! I& ]
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。
3 u2 n- q. K6 g% e/ D; W: y. \9 r* Z" T7 Y G/ G% Q, B
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。
. q+ H3 Q5 p$ W+ V7 T5 Z2 k, R3 J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。
* f5 x% ]! e3 r* e$ b1 a3 v: v% _* v% X9 j+ X
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 n) p- y% L" |6 a+ D* M. k+ o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。) M8 l. G1 _! j5 b7 L
