手把手教你使用长编码功能5 U3 N: z6 Q3 o" p# 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:
, m# i( L' t# D, ~4 t9 p8 E1 P& T& f; I% Z* g" m' U2 q3 k* P
018D8F020004100000120C000000000000087F075C
# x+ k9 q0 ^3 b6 {6 Q% h" r7 [8 A7 m" d3 q& a) t/ a; v
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204 `! s! l, C+ ^" b+ ~6 e) f3 A
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。4 i4 m& C" Z0 [
0 ?- ]3 X* _1 N% p; O3 ^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。
/ L+ [9 c( z* Q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。
2 I4 ?) A }9 d6 }
( D4 l& ?+ ]2 a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。! {6 K% m. L( y3 b& Y& 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。
