手把手教你使用长编码功能. c# b+ t" @+ n. q
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:- e. o6 [, K" e' k
3 O; O1 i7 u0 k7 a" C% K. p, H
018D8F020004100000120C000000000000087F075C
! X5 f* A* O; `9 l+ h% ~0 [
7 S5 ^3 f+ a( \* e( u09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" B1 J9 k& Y) z$ H- n
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。
/ G: f8 P' `# u! ^7 f/ E8 S3 v, g, y8 d$ A9 A7 n# t [) w/ ~& c) q7 ^
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。
0 S1 D' P* y* M9 c8 v/ o# j/ K/ i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。8 s+ I1 j/ {; r6 J
# P f( q( ~3 [4 ]$ o$ D1 \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。
/ g' u) L7 s: y1 t4 ^# {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。- d5 t# A) P% [
