Often it is necessary to add some logical control to a MATLAB algorithm to allow the generated hardware to function correctly in the overall system. This lab exercise will explore how hardware control can be added to a MATLAB algorithm and synthesize

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
