手把手教你使用长编码功能" v1 u8 D" w6 g8 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:
$ Z' t& N ]- ~8 \+ Z7 w7 f5 g4 z2 I
018D8F020004100000120C000000000000087F075C$ x& i' x9 W! Q
. G, [: b. l% ^: @- K! ?% j O$ C+ ^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
& ]1 T; f' i2 G. {, f: n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 t6 F- N' `5 f, d: q
9 c2 t ?; f t1 Q/ h. p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。
% C2 d. g& ~" C' K8 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。6 S' H1 ]5 R3 A7 M5 p; G
; m/ P1 {( n, N2 n) M; J$ S& n. H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。
) t0 }4 [, ^9 G" b0 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。
