Working Principle

This mini oscilloscope project aims to create a compact and user-friendly device for audio enthusiasts and electronics hobbyists. The oscilloscope is designed to measure and display electrical waveforms, allowing users to analyze circuit behaviors and diagnose issues.

The primary components include a GD32 microcontroller, which handles signal processing and user interface operations, and a display module to visualize the waveforms. The oscilloscope captures input signals through probes, processes them using the microcontroller, and displays the real-time waveform on the screen.

Description

This project was part of the Lichuang Training Camp, where I learned about simple oscilloscope principles, PCB design, and GD32 microcontroller programming. I also explored the capabilities of Lichuang EDA for designing enclosures and panels.

The device is designed for practicality, with input probes on the left for left-hand operation and function buttons and knobs on the right for right-hand operation, aligning with common usage habits. The enclosure was designed using Lichuang EDA, highlighting its user-friendly features and powerful capabilities.
