摘要
设计了一个基于单片机的液晶显示综合应用控制系统,能够显示当前温度值并绘出实时温度曲线。系统硬件由AT89C51单片机、并行A/D转换器AD1674、8255I/O扩展接口、字符液晶显示器LM016L和图形液晶显示器AMPIRE128×64构成。分别在Proteus和Keil环境下设计了系统电路原理图和系统程序,并在Proteus中进行了软、硬件交互仿真。通过实际电路焊接调试,完成了系统功能,实现了各项技术指标。
A complex application system of liquid crystal display based on single chip computer control is designed which can display current temperature value and can draw the real temperature curve on LCD. The system hardware is constituted by single chip computer AT89C51, parallel A/D converter AD1674, I/O extended port 8255, character liquid crystal displayer LM016L and graphical liquid crystal displayer AMPIRE128×64. The system circuit schematic diagram and program are designed in software Proteus and Keil respectively. Meanwhile, the system hardware is interactively simulated with system software in Proteus. Finally, the system function and every technical index are performed through actual circuit welding and debugging.
