手把手教你使用长编码功能$ l- r8 E: Q7 g6 v0 V2 P' Y; f
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:" J& a6 p1 U$ _2 U3 O9 l
9 ^: y6 V' `& ]4 _/ ?$ O. k9 k* U018D8F020004100000120C000000000000087F075C
8 K7 i6 R! W; p# h( q& R: L! J" d& y8 e
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
7 c9 X3 \! E4 e, H6 @. e" }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。4 w6 R& w, H# m! Z
' F1 H5 i: J& v! V- k& Y* 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。# I( R8 R" h& o- C4 W+ }
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。" v( T: N5 R/ l5 t- n8 `
! p* b |6 F4 y9 J: I, O# k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。' D j. [- H8 N, C8 g* l
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。4 {8 M# X5 G' U \3 ?( Q/ E
