Innovative Design of MCS-51 Single Chip Microcomputer Experimental Teaching Based on Model Design

为培养学生的创新设计能力,以单片机流水灯实验为例进行了教学创新设计。首先在Simulink中用Stateflow有限状态机构建流水灯的单片机控制模型,然后对模型进行仿真测试和SIL软件在环测试,满足控制要求后自动生成C51程序代码,并移植到Keil进行调试,结合Proteus仿真软件验证流水灯的控制效果,测试结果表明模型设计完全符合控制要求,并给出了实验项目的实施方案和考核评价要求。结果表明基于模型设计的单片机实验教学能使学生系统掌握图形化的建模、仿真、测试、代码生成和系统调试的方法,有效提高了学生的综合设计和创新应用能力。

In view of the lack of students'programming application and innovation ability in traditional single chip microcomputer experimental teaching,the innovative design of single chip microcomputer teaching based on model design is introduced.Taking the experimental innovative design of single chip microcomputer running water lamp as an example.Firstly,the single chip microcomputer control model of water lamp is built with stateflow finite state mechanism in sumulink,and then the simulation test and SIL test are carried out on the model.After meeting the control requirements,the C51 program code is automatically generated,and transplanted to keil for debugging,combined with Proteus simulation software to verify the control effect of running water lamp,the test results show that it fully meets the control requirements,and gives the implementation scheme and assessment requirements of this experimental case.The results show that the single chip Microcomputer Experimental Teaching Based on model design enables students to systematically master the methods of graphical modeling,simulation,testing,code generation and system debugging,effectively improve students'comprehensive design and innovative application ability,and meet the training requirements of students'comprehensive innovative design ability under the"new engineering".
