手把手教你使用长编码功能
) `$ b' `9 V* K2 Y: `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:
2 d0 N# T+ n7 V* z0 |' Z$ u( W# s! ]; a# F# c! l
018D8F020004100000120C000000000000087F075C1 ?; f1 D1 r+ g+ L
8 x8 }+ j% z! U C Z( k# x0 T+ U
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 W5 S6 \7 }9 L
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。
4 c, ]9 _/ A5 o9 S- z& L" h( W( p
) B2 }2 C% {; I: R- 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。
% q4 f/ W% y% i2 R, f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。* M# o& o9 N) z4 R p9 |1 S3 H2 W; q
1 \ W' n+ `: U1 s: c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。1 {8 w( q/ Y. }. \% G% z( g
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 x: W4 E3 o1 Y9 a0 z& S" g, T
