摘　　要：针对Proteus仿真液晶LCD1602出现的问题,对LCD1602技术手册中的读写操作时序图进行LCD1602相关引脚时序逻辑电平分析,通过Keil4的逻辑分析仪对程序中LCD1602的读写时序进行查看,根据逻辑分析仪的时序波型对液晶显示程序代码进行修改使程序符合LCD1602的读写时序要求,并使用Proteus的图表分析对电路程序代码执行时的电平进行查看,直观显示了程序在电路执行的过程。在嵌入式系统开发中使用Keil4时序逻辑及Proteus图表仿真,可以对软件及电路中出现的问题有针对性的分析,探索了使用Keil4的逻辑分析仪和Proteus的图表分析对程序执行时序进行分析的新方法。This paper introduces the functions and application fields of Keil and Proteus two software,introduces the situation of embedded simulation at home and abroad.In view of the problems in the Proteus simulation of LCD LCD1602,technical manual on the LCD1602 read write operation timing diagram LCD1602 pin temporal logic level is analyzed.Through Keil4 logic analyzer on procedures LCD1602 read and write timing view.According to a level of temporal logic analyzer wave type,liquid crystal display program code is amended to make the program in line with the LCD1602 read and write timing requirements.The Proteus chart analysis of the circuit program code is used to be executed when the view.It intuitively shows program in the executive circuit.In the embedded system development,by using Keil 4 temporal logic and Proteus simulation graph,the problem of the software and the circuit is analyzed.The paper also explores a new method of program execution timing by using Keil4 logic analyzer and Proteus chart analysis.
