手把手教你使用长编码功能- M7 e3 h9 `& m2 x4 s$ t9 a, L
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:. m" l6 f2 {' e+ x& g' `6 i
5 o' z" |2 w' }/ r0 [( k
018D8F020004100000120C000000000000087F075C& R7 N+ k b% V$ C
: P4 A1 o0 x: V! h: N
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
' s, E6 h$ p: p8 c0 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。' l) p1 |8 J9 q2 D+ B$ o+ A) ^5 X: ^
4 P: }5 [, A- a& G7 _
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。: |5 o6 R1 D9 T' c) `" _3 x, j$ l
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。

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。, q: u- O4 Q/ i+ S* A% _/ K
