摘要
液晶显示器广泛应用于各种仪器仪表中,为了使液晶显示器的接口电路达到最优化设计。对单片机与液晶显示器的3种接口电路形式:间接控制方式、总线控制方式(2种电路),及汇编语言程序设计,进行了详细的分析比较,重点分析了总线控制方式。并采用AT89C51单片机和液晶显示器LM1602为模型,利用编译软件Keil和仿真软件Proteus,进行了编译和仿真。结果表明总线控制方式生成代码量最小,程序执行效率最高,为此类显示电路的设计选择及优化提供了工程参考。
The liquid crystal display has been widely used in various instruments, in order to LCD interface circuit optimized. On three types of MCU and LCD interface circuit forms：indirect control, bus control mode （two circuits）, and assembly language programming, carried out a detailed analysis and comparison, analyzed the bus control mode. Used AT89C51 MCU and LCD-LM1602 as the model, used compiler software Keil and simulation software Proteus, was compiled and simulated. The results show that the bus control means the minimum amount of code generated, and running the most efficient. The design provides a project for Selection and optimization of LCD circuit.
