Serial Port Programming Example Implemented with MATLAB GUI

This is a serial port programming example implemented using MATLAB GUI, designed for undergraduate graduation projects. The system includes two client applications: one for data transmission and another for data reception. The implementation utilizes MATLAB's Instrument Control Toolbox, specifically employing serial port objects and callback functions to handle asynchronous data communication. Key functions like fopen(), fwrite(), fread(), and fclose() manage port connections and data flow, while GUI components use event-driven programming with pushbuttons and text areas for user interaction. This example helps students understand serial communication protocols, data framing techniques, and real-time data processing through practical MATLAB coding. By implementing handshake protocols and buffer management algorithms, students can deepen their understanding of data communication principles and applications, thereby enhancing their technical skills and preparing for future professional work.
