LM311_Proteus

51单片机C语言学习，C语言来编写单片机程序。Proteus仿真。(51 MCU C language learning, C language to write MCU program. Proteus simulation.)

实现正常时钟功能，带时间日期，三组闹钟，键盘显示(中断程序)(Realize normal clock function, with time and date, three sets of alarm clocks, keyboard display)

基于51单片机的按键例程，常见问题： 1. 按键无反应 请您确认程序是否下载成功，连线正确无误，确认无误后还是无效果的话，将排线重新插拔下，单片机拿下来重新安装，重启开发板试试！(Key routines based on 51 single chip microcomputer,common problems: 1. Press the key and no response. Please confirm whether the program was downloaded successfully and the connection is correct. If it is still ineffective after confirmation, plug and unplug the cable again, take down the MCU and reinstall it. Restart the development board to try!)

本程序利用51单片机的定时器中断产生时间信号，同时具有通过按键调节时间的功能，还可设置闹钟(This procedure using 51 single-chip timer interrupt time signal, but also has the functions via buttons adjust the time, but also set the alarm)
