Introduce simple engineering projects from JLCPCB EDA to freshmen with no prior experience.
No soldering required, lowest cost, showcasing the campus scenery.
Based on STM32F411, the high-speed DAP-LINK has a download speed similar to, but slightly faster than, that of Zhengdian Atom's high-speed DAP-LINK.
This module uses the STM32F411 as the main control chip, employs the open-source DAP protocol, and utilizes high-speed USB for high-speed downloading. It follows the layout of Zhengdian Atomic's high-speed DAP-LINK and currently only supports SWD functionality, with a virtual USB serial port.
This project includes a casing and has been 3D prototyped for verification.

[Microcontroller] Simple Oscilloscope Project Based on GD32 Microcontroller
Oscilloscope
Project Description:
This project is a simple digital oscilloscope based on the GD32F103C8T6 microcontroller, designed to measure and display waveform signals. An external signal input is used to feed the waveform signal into the microcontroller for sampling and processing, and the waveform is displayed in real-time on an LCD screen.
Main Functions: 1. Waveform Signal Acquisition: The waveform signal is input to the analog input pin of the microcontroller via an external circuit, and sampled using the microcontroller's analog-to-digital converter (ADC). 2. Waveform Processing: The acquired analog waveform signal is digitized, including data processing and filtering. 3. Waveform Display: The acquired waveform is displayed in real-time on the LCD screen for user observation and analysis.
Hardware Components: 1. GD32F103C8T6 Microcontroller: As the core control unit of the project, responsible for acquiring, processing, and displaying waveform signals. 2. LCD Screen: Used to display waveform images and provide a user interface. 3. External Signal Source: Provides the waveform signal to be measured; this can be any circuit or device that generates waveform signals.
Software Design: 1. Waveform Signal Acquisition and Processing Program: Utilizes the microcontroller's ADC module for digital sampling and processing of analog signals, achieving waveform data acquisition and processing. 2. Waveform Display Program: Through an LCD driver, displays the processed waveform data on the LCD screen, forming a waveform image. 3. User Interface Program: Designs a simple and intuitive user interface, including waveform display, trigger settings, and measurement parameter display functions, providing a user-friendly operating experience.
Project Features: 1. Ease of Use: Employs a simple hardware and software design, making the oscilloscope easy to operate and learn, suitable for beginners and enthusiasts. 2. Openness: The project has a certain degree of scalability and customizability; users can expand and optimize functions according to their needs. 3. Educational Value: As a simplified implementation of a digital oscilloscope, it can serve as a teaching experimental platform, helping students understand the working principle of oscilloscopes and the basic methods of digital signal processing.
Through the above design, a simple digital oscilloscope based on the GD32F103C8T6 can be implemented for measuring and displaying waveform signals, possessing certain practical and educational value.
