手把手教你使用长编码功能
8 L: R3 i2 Y/ Y. B% |5 U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:
( F$ ?! _/ `+ T+ ^2 q6 K) O
' g' W, r' _. N6 |018D8F020004100000120C000000000000087F075C# u& B" ~! Q! A6 }- f% t, Y8 i
, ~% Y& W% U9 { r7 ]9 b, z. O09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' z3 h! x8 A% C6 O; L5 j
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。
5 t2 r4 Z. U2 D& D, L6 R5 D3 w; M E; Y8 q8 @7 f- m4 Q
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。2 @: X7 \! L+ y+ w0 n+ t% n& u
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。/ _7 u5 t' _: a% O2 [
6 D9 D7 N7 E" o/ d( N g
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。* M" `3 I& c$ S2 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。; X) r5 ~4 L6 H% q/ _* j
