手把手教你使用长编码功能* y4 [% s8 h* p% E
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:
; P2 M1 }0 E0 m: ~% J! W0 E; e$ E; m$ r- W R4 O
018D8F020004100000120C000000000000087F075C/ S% G& K+ h0 _) Q
& y# w7 x$ q7 b
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/ s$ l; C- }3 v; I$ e+ _5 w* w
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。3 c3 J7 r3 n8 r" o3 j M' i/ I" e
4 ~, }, M0 I; K3 B- E# N% A5 c; Y, v. [
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。- x* h; x2 l6 C8 f
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。: C& o2 O: [6 U) W
4 ^' x. N( @7 H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。+ s# }0 K7 B# l9 |2 ~* Q
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。) U# y! G% k0 U3 }5 P0 b

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。
