自己做的8位竞赛抢答器仿真与代码

可能有些小毛病仿真没毛病，就是自己的那个开发版出不来，大家拿去研究研究

仿真原理图如下需要用8.0以上的版本（proteus仿真工程文件可到本帖附件中下载）

单片机源代码如下:

很好很好

ID:364880 · 发表于 2018-7-6 12:16

没流程图啊

ID:138664 · 发表于 2018-7-12 23:58

用8.6报错

ID:413212 · 发表于 2018-10-21 18:43

流程图有吗？

ID:575686 · 发表于 2019-7-1 19:25

请问这个要怎么复位啊

ID:577047 · 发表于 2019-7-3 12:18

好东西

ID:682860 · 发表于 2020-1-7 14:03

这个有流程图吗

ID:682004 · 发表于 2020-1-7 15:09

自己在protues上走了一遍程序，还可以，不错

ID:682955 · 发表于 2020-1-7 15:22

可以的，正要做这个
