Matlab是常用的演草纸式编程工具，好多非计算机专业的都可以掌握，若能利用它控制实现与单片机、DSP等下位计的通信，则可轻易实现控制与数据的采集，然后利用matlab强大的运算和处理功能进行后继的处理，这样对于研究生作毕业设计非常有利。利用Matlab实现控制串口通信，控制下位机，VC.m是起始界面，其他的为子程序，希望对大家有帮助。-Matlab is commonly used toilet paper speech programming tools, a lot of non-computer professionals can grasp, if the use of its control with single-chip, DSP wait for the next bit of communication, can easily realize the control and data collection, and then use matlab powerful computing and processing capabilities to carry out follow-up treatment, such as graduation project for graduate students is very beneficial. Realize the use of Matlab to control serial communications, under the control of digital machines, VC.m is the initial interface, the other for the subroutine, in the hope that everyone has to help.
