手把手教你使用长编码功能
" p% |2 M2 C u `. n+ U: `% X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:5 Z; i# O9 C2 e6 t$ h# i& S
8 ^& A/ X7 N6 f6 T7 ~; M3 E
018D8F020004100000120C000000000000087F075C1 v2 K, l( t z" z" U3 `1 {- ^6 E4 a
0 C+ z5 Y+ o% y+ f8 E09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/ e) ?4 E1 H5 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。
" B. N- J3 q4 r; r/ \& N- g* A: @) u1 F. Z1 c
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。3 v5 B' `6 c- M% A, B( ]7 H
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。
: f8 v7 l9 q6 G' E1 c) M, M0 Z# V x* j- S% W& q
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。
' e# l% e* K+ Z/ D: f G& g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。; h# O/ O3 h, d+ }, F5 ^3 ^

那么我们只需要把byte00的bit1 bit5 bit7位由0变成1,这样原来的byte00位00000001就变成了10100011+ P- Q# G7 v' G9 Q- v/ g1 G
然后我们再用windows的计算器程序把2进制变为16进制,转换回去的byte00的16进制编码就是A3。
