手把手教你使用长编码功能
4 C" O w+ k: ?9 T* }( V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:' a z% J# }+ P
* K ?5 U8 ~; R1 i* I

+ t7 y) y q. D: 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204 j$ z4 p5 M* K! x+ W
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。2 ]* `+ x' R) n% K* |
1 u1 A% g/ _ t( h8 y. f& T" e3 x5 C
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。2 h, r9 x. z2 U% S
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。
5 B, ?' X% @8 M% j& o4 p6 S
4 F$ q7 `9 }$ s6 L* _3 d' h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。
3 Q. _" V3 d% u( f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。7 w4 O) q! ]/ }: O8 M( Z7 S$ l9 W

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。& b3 r% o1 u6 k ?; N- h
