手把手教你使用长编码功能# ^6 r' h/ J. \
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 C& B5 ]- g* s y. [6 u" D' J; G
8 g4 F, w4 W. A
018D8F020004100000120C000000000000087F075C
( j }% F m0 K: l4 e2 e, r0 | i- C; f6 Z
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& C- N/ o: t2 F1 V5 `: Z w% V1 J
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 B+ s" W1 Q' ~$ h% p$ W7 r) A
1 d: H* h. F: v q4 X4 D" 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。
, [! ~, n/ b Q2 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。
/ Y h- {. |3 k. _$ c# u5 r2 e9 Y$ ^9 j% |: q
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。, r$ V. b8 p. @ o
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。/ O# o) X: [. E) X

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。( I4 F* X5 S3 i6 \1 E
