手把手教你使用长编码功能/ a/ a" g1 l/ y1 U
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:
) x7 w7 K, i( Y1 ]/ A. e' v$ w4 U. s% M; V
018D8F020004100000120C000000000000087F075C# E* j6 N! Z" x- F( ^
6 `% w! {$ W% k2 H( f
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
# C4 R- o) y' J- X( z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。- I9 b$ w; Q/ h3 G! p# @
' v' B; X! w( J$ M7 o+ d6 P# E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。$ z, b8 ?5 |; i7 L; ^5 r
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。
: A) R; g0 ~. G
, p' Y, X2 v6 G/ S2 ]% V; k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。! v# _5 ^! f' ~- N2 ]& S, Q" 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。) X8 q5 ]3 r$ E( C) B
