开发板测试程序:要求:串口提示测试项目根据输入单片机进行相应的测试具体流程如下:首先单片机一上电串口输出如下所示选项假如选择测试DS1302 电脑键盘上输入数字8再按下回车进入下面界面开始1302的测试只要键盘上按下ESC键即可终止测试回到选择界面锻炼技巧:串口通信各种常用单片机外设的驱动技术 :

程序作用:测试单片机串口功能将串口接收到的字符重新发送到串口上程序在STC12C2052AD上实验成功晶振为使用串口调试软件测试单片机收到回车键即显示你发送的字符 单片机交流:QQ949725852 include<> define uint unsigned intdefine uchar unsigned chardefine word_num 32 能接收的字符字数当然不能
