手把手教你使用长编码功能
2 d- C; M$ I. L0 J2 {8 y7 N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:
5 h: z" U% S, w. g5 b. S" S
- U# S- Q/ j: P) @* i# z) r018D8F020004100000120C000000000000087F075C }6 h3 n: Q, F
. p1 ? ?* P7 v& ~* e5 Z
09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 p6 Z3 M% X( b- Q4 e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。
+ J) S- W3 x- a9 n
; g2 j: l5 U/ D" a/ [; l- s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。
6 L6 i! T1 Q! p3 @. Y3 a+ 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。2 v2 L* m3 l) _+ f6 }& _
# R m" \! F" r# i e# L& N) }
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。# i- q/ g4 T) ?- B; D7 ?8 S: J8 r9 W
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。
