手把手教你使用长编码功能1 f- H* t0 c4 F+ h: n
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:6 p+ ?5 J/ f9 ?" m f
/ V; N# e) d8 n) j0 |( S# w
018D8F020004100000120C000000000000087F075C1 P0 _; [0 h" a. s' O- ] q$ i3 l
# X/ t" j! J# f& H7 A
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' ?! a2 x, z" R- z( I9 ~
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。6 @( P5 P7 |$ P
) e% l0 \# X8 G2 M; P: @' S
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。
9 a+ p( N+ P1 W5 R% S9 L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。2 y/ j; e- U4 `
2 B* |3 `8 @- x+ W( ^9 l. 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。
