手把手教你使用长编码功能
1 h$ p3 N6 B0 d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:! r6 F. @1 _, J ^ U( @
8 I! Z: O8 W. @. `9 ~ C018D8F020004100000120C000000000000087F075C
; A! _* @9 x( P; j) a ], u9 }( n9 V# n+ P W
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203 n9 u6 |5 X3 @% S0 X4 b: D
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。% U' T6 W' X5 ~, k! E) G8 a0 `8 P
2 A/ b# y# ~2 k- n
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。/ f7 r. x3 ?/ \/ y1 ~; ^% G& L3 ]! h
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。
0 X+ F' n2 j( u
4 l& ~+ _* r5 _$ s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。
. n6 m; C1 @0 _0 m, u; \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。! t- o9 X# o6 u. O. Y3 d
