手把手教你使用长编码功能! L7 P- ~$ d6 Q+ N: c, z
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:
) e7 i7 @+ `& K; o ]* ~
7 @7 b. y* A$ r( n8 ~* c018D8F020004100000120C000000000000087F075C4 W6 `5 |! P# y+ d, m' k
) }" O0 I5 o- G3 w- K
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! L {$ v* `3 _
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。9 Q6 z( U( W# s7 r
3 L) K) c" W; e, y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。
; Y b$ z; C: r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。+ ~0 D( e: K& l% W; c
# @9 n. w" k6 w
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。
* j7 P7 I- z0 U9 U2 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。# q$ K4 W) m' z" w% B& Q% N
