实验七数码管动态扫描显示实验姓名:丁亚芳专业:通信工程学号:成绩:;;。。要求利用P0口作数码管的段选线,~,其译码输出Y0~Y7作为数码管的位选线。,将数字1~8分别显示在8个数码管上,要求显示无闪烁。,利用Proteus中的“激励源/DCLOCK/数字类型/时钟”产生频率为1HZ的方波输出,并利用定时/计数器T1统计脉冲的个数,将统计结果动态实时的显示在数码管上。该脉冲计数电路的基础上自行修改。三、;,编译通过后,与Proteus联合调试;,观察数码管显示是否正确;,仿真调试、运行程序并查看效果;(如100KHZ),观察显示情况。四、电路设计及调试(1)动态数码管显示电路设计统计脉冲的个数并显示动态数码管显示编程#include<>#defineucharunsignedchar#defineuintunsignedintucharcodedis[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};ucharcodewela[]={0xf8,0xf9,0xfa,0xfb,0xfc,0xfd,0xfe,0xff};voiddelayms(uintc){uchara,b;for(c;c>0;c--) for(b=142;b>0;b--) for(a=2;a>0;a--);}voidmain(){uinti;P0=0;while(1){for(i=0;i<8;i++){P1=wela[i];P0=dis[i+1];delayms(1); }}}统计脉冲个数并显示#include<>#defineucharunsignedchar#defineuintunsignedintucharcodedis[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};ucharcodewela[]={0xf8,0xf9,0xfa,0xfb,0xfc,0xfd,0xfe,0xff};chari;uintcount=0;ui
