手把手教你使用长编码功能
) K" k; d& N4 Z) A% H; b+ 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:
\! \, r1 R, x8 g O9 a/ y: ]) c$ g/ l$ `. E
018D8F020004100000120C000000000000087F075C
3 f. m- R( r2 ?0 Q# k* D" `# E. t( T6 z2 A7 n
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
% x" t+ L: M" A. q' h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。
* q% ?. d. z! M& U( o3 ^0 p5 d4 t) j. ?0 q& f; i/ q. K" [
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。* E4 w7 ~( i0 ?' U: r; Z6 P
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。* Y$ g7 W2 h4 l, g- @7 G
# I8 ?' z8 R" b; Z: T" c+ M3 `) z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。$ F7 ^" K0 e" Y7 n* l
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。& {0 Z$ d9 e% q) c7 y- ?
