手把手教你使用长编码功能4 l$ q' U# u* n( u3 g G
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:
* R+ t, Z m1 R/ r1 F: x$ W/ |8 K+ G( [
018D8F020004100000120C000000000000087F075C
# s$ }0 O- X8 O" _1 ]0 }, |' x& L4 H2 C' d2 [! R
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
) {% d( E0 W( E5 m* D" n0 o4 H* u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。% @; E9 e \- y& F
/ w' F/ l3 v% F' ^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。! K$ u9 @1 P9 J. e' [/ s- l$ Z. Q( A
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。
# e% P& w) L; L4 ? X6 p# y" G- v) i0 Z- g' B
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。6 s W) D3 t$ P6 ]6 ~ Z
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。
