Real-time Multi-Channel Serial Data Plotting with GUI Interface in MATLAB

This project implements real-time plotting and display of multi-channel serial data within the MATLAB environment, featuring a custom-designed graphical user interface (GUI) for operational control. The implementation utilizes MATLAB's Serial Port Object for serial communication management, where each channel is handled through separate serial port instances with configurable baud rates and data formats. The GUI interface provides convenient data monitoring and analysis capabilities through interactive controls. Users can adjust plotting parameters and styles dynamically, enhancing data visualization with customizable line colors, markers, and axis properties. The system employs MATLAB's timer objects for real-time data acquisition and callback functions for continuous plotting updates. Additional functionality includes data export capabilities through file I/O operations (fwrite/fprintf) and plot saving using MATLAB's print or saveas functions with various format options (PNG, JPEG, PDF). This allows users to perform personalized data processing and presentation according to specific requirements, with the architecture supporting expandable features through modular function design.
