手把手教你使用长编码功能
: X( p% I% L5 R3 O1 Z3 \+ Z$ y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:, ]6 w2 y, I/ {9 ?
5 e9 a: i( k7 c: w! {4 a4 {! }
018D8F020004100000120C000000000000087F075C3 @4 Z; Q8 m) L
7 _- C) p$ w, b4 `7 D09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' ^ s2 b d: T) y4 _- G% N: V- @- v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。
6 p1 I4 {# z5 G- D% f% E
0 m# T; M2 D) O2 I8 [: J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。 t3 w- I2 ~+ I: c. x5 }
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。
& y3 q) p7 k* R" j. \9 n0 w/ B& N$ d6 X4 d/ ]# ~: _: G( C1 E
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。1 \2 T/ U& v: z* C+ Y" N6 ]0 D8 ^
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。8 b1 O" Y, I) B9 p2 k1 O& M2 {
