手把手教你使用长编码功能! U0 U, `' [# U. ~6 e& B7 B: o
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:
$ E* c8 o" A8 |( I# w5 G5 V8 B" E1 s& M! K/ o1 \
018D8F020004100000120C000000000000087F075C
K9 Y1 ?0 o9 [+ x: I' s0 q2 a
; p2 H% y( f( A09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 J& n6 L$ I4 r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。; K9 Y" ]3 s$ F
$ B8 u" ]# h( m8 }& _+ 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。
$ s& P4 }( J* B" W3 E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。
% k6 t; B2 i A3 N U' P
9 {) |; Y n5 |- s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。
) h' f3 S7 ^, S, h! F1 { ]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。6 m, x. y# B6 o( q1 O' S( l- |! q( t- _

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。
