| 摘 要： | 基于Multisim10仿真软件,设计单片机的虚拟串口驱动LCD1602液晶电路。实现了虚拟串口扩展并行输出的功能。该设计适用单片机UART串口被占用时,以最少的单片机I/O口驱动LCD1602,满足显示电路中复杂信息的需求。与传统的设计手段相比,在Multisim10平台支撑下,设计电路更方便快捷,并可通过仿真结果直接观测和验证设计电路是否达到要求,具有省时、低耗、高效的优越性。

| Abstract: | Using Multisim10 simulation software,we design a display based on LCD1602 drived by fictitious serial port of single chip microcomputer. It is realized that the output in parallel is replaced by fictious serial port.It can be applied in driving LCD1602 by the least I/O of single chip microcomputer to show complex information,as the UART serial port is occupied.Based on Multisim10,it is easier in designing the circuit than by the traditional methods,and the circuit can be simulated directly on computer to te... |
