结合单片机和M a t l a b 两者的优点，基于事件驱动的中断通信机制，提出一种Matlab 环境下PC 机与

单片机实时串行通信及数据处理的方法；完成单片机数据采集系统与PC 机的RS-232/RS-485 串行通

信及其通信数据的分析处理、文件存储、F I R 滤波及图形显示；简化系统开发流程，提高开发效率。

该方法已成功应用于一个P I C 1 6 F 8 7 6 单片机应用系统实例之中-Combination of single-chip and M atlab strong points of both, based on event-driven interruption of communication mechanism, a Matlab environment PC and MCU in real-time serial communication and data processing methods　complete single-chip data acquisition system with PC-RS-232/RS-485 serial communication and analysis of communication data processing, file storage, FIR filtering and graphical display　simplify the system development flow, improve development efficiency. The method has been successfully applied to a PIC 1 6 F 8 7 6 examples of single-chip microcomputer application systems
