基于 LabVIEW 的单片机与 PC 机串口通信显示系统设计

摘要

为了实现上位机与下位机通信，设计了基于 LabVIEW 的单片机与 PC 机串口通信显示系统。系统的显示模块可直观地显示通信数据，并解决了串口通信与字符液晶显示时序冲突的问题。本系统可作为 NI 系列板卡的显示模块，具有实际工程应用价值。%In order to realize the communication between the host computer and slave ones,the LabVIEW-based MCU and PC serial communication display system was designed.The display module in the system can visually display the communication data so as to eradicate the timing conflict incurred by the serial communica-tion and character LCD display.The improved system can be used as a display module of NI series boards and it has applicable value.
