手把手教你使用长编码功能
- D7 M7 v# W/ a- \9 S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:( t6 }' I9 n8 O: M
5 J7 P/ f; T9 f4 q6 m$ a018D8F020004100000120C000000000000087F075C7 B. S9 C6 ?( O
4 R5 s$ e1 N/ E9 `& _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204 l) V; n6 t1 I6 s+ 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。) x m) ^) H3 M% [6 z
+ \% j& P- _ J1 Y; ~/ o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。
1 J+ b/ W; R w3 c) R$ ~( L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 {0 t$ i% s ]* _+ `
8 Y; \5 D! N' [$ C7 T( i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 z5 G* x0 \2 ~0 }8 }
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。
