手把手教你使用长编码功能8 o5 a( ]0 r3 d
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 J; p3 S6 [- U: u+ ~
/ J: s5 v7 p( l- a7 W8 Q018D8F020004100000120C000000000000087F075C
* q8 D _2 X: r& W7 L5 v# M9 H' F: Q$ A K
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/ J, t, o1 S7 ?: `/ t3 t; r0 M
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。% e3 R: Y' j( p7 E9 e
3 k$ G: E0 U- R. {0 j0 `! G i) h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。, e% s9 `, M/ g% ~2 M/ u* {
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。0 V) z1 C! t; y
$ s b& `- y7 L z/ u/ d5 g _
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 m7 i v* ^5 T: @9 N( R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。

得到了上述的编码后,然后我们再来看09长编码的功能对照表。
