手把手教你使用长编码功能
e6 G$ P4 y' o! J e# p1 F9 [9 Q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:
, S' S8 D: V* c+ _0 w
' I. J: \% D$ X/ {018D8F020004100000120C000000000000087F075C
9 s( o; q2 @$ b& F% }5 Y
' B! y) i4 [9 x& ?. g- ]+ u09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
2 Q- I% e" z n! E! g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。
L: a2 s% w. q$ m$ H/ G9 u: k0 ?6 S: q4 q
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。; C& p* r4 v' G7 c) Q$ W
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。
% Y7 ]9 q; y, I6 b4 L/ k; f2 X( R2 H) B# M
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。
& |$ C3 @, b' o# ^. R; 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。% S7 E' M0 F% E: E7 ]! ?/ l+ ?. l( w1 \

那么我们只需要把byte00的bit1 bit5 bit7位由0变成1,这样原来的byte00位00000001就变成了10100011, W" I5 C; W8 u1 k
然后我们再用windows的计算器程序把2进制变为16进制,转换回去的byte00的16进制编码就是A3。
