Question

单片机51的C程序谁给解释下?#include #include unsigned char code displayb

Answer 1

unsigned char code displaybit[]={0xfe,0xfd,0xfb,0xf7,

0xef,0xdf,0xbf,0x7f};定义数码管显示位选数组

unsigned char code displaycode[]={0x3f,0x06,0x5b,0x4f,

0x66,0x6d,0x7d,0x07,

0x7f,0x6f,0x77,0x7c,

0x39,0x5e,0x79,0x71,0x00,0x40};定义共阴极数码管显示编码数组

unsigned char code dotcode[32]={0,3,6,9,12,16,19,22,

25,28,31,34,38,41,44,48,

50,53,56,59,63,66,69,72,

75,78,81,84,88,91,94,97};定义ds18b20表格数组

unsigned char displaycount;定义变量

unsigned char displaybuf[8]={16,16,16,16,16,16,16,16};定义显示缓冲

unsigned char timecount;定义变量(计数单元)

unsigned char readdata[8]; 定义变量

sbit DQ=P3^7;定义连接ds18b20端口

bit sflag;定义标致位
