📦 基于单片机八路抢答器的仿真与设计 - 免费下载

设计了一种基于STC12C5A60S2单片机的八路抢答器,由P3口八位控制八路抢答选手,抢答成功的同时对应选手位置的LED小灯点亮,与选手对应的指示灯由P1口控制。设计包括数码管显示模块,用来进行显示复位、开始、选手号与提示时间信息,单片机控制模块,处理按键与数码管显示,按键模块对选手是否抢答进行按键检测,和报警模块,实现超时未抢答和倒计时时间进行报警功能等四部分。实验结果表明,该8路抢答器的设计达到了预期的要求,具有反应快、操作简便、硬件电路简单、成本低廉等特点。

An 8-way answering device based on STC12C5A60S2 MCU is designed.The 8-way answering contestant numbers are controlled by the P3 ports.At the same time,the LED light corresponding to the contestant position is lit,and the corresponding indicator light is controlled by the P1 ports.The design includes a digital display module for display reset,start,player number and prompt time information.The MCU control module handles the display of keys and digital tubes,and the keyboard module detects which competitor presses the button firstly.Alarm module achieves timeout and no answer and countdown time for alarm functions.Experimental results show that the design of the 8-way responder including the above four modules meets the anticipated requirements and has the characteristics of fast response,simple operation,simple hardware circuit and low cost.
