#Training Camp#Oscilloscope

1. Overview: This project aims to design and build a simple oscilloscope for displaying the waveform of input signals. The oscilloscope will acquire analog signals through a microcontroller and present the waveform graphics to the user in real time via an LCD screen. 2. Hardware Design:
1. Microcontroller: A GD32 microcontroller with sufficient processing power and rich library function support will be used as the main controller. 2. Analog Input: External signals will be received using analog input pins, and the analog signals will be converted into digital signals using an ADC (Analog-to-Digital Converter). 3. LCD Screen: A 128x64 pixel LCD screen will be used to display the waveform images in real time. 4. Power Supply: A suitable power supply circuit will be used to convert the power supply to the operating voltage required by the microcontroller and the LCD.
3. Software Design:
5. Signal Acquisition: GD32 standard library code will be written to configure the analog input pins and use the built-in ADC library functions to sample and convert the analog signals. 6. Waveform Display: Waveform images will be drawn on the LCD screen using graphics library functions. Basic graphics drawing algorithms can be used. 7. Interface Design: Design a simple and intuitive user interface, controlling the oscilloscope's operation via buttons or knobs, such as selecting the sampling frequency and adjusting the display range. 8. Signal Processing: Add signal processing functions, such as filtering, peak detection, and spectrum analysis, to enhance the oscilloscope's capabilities. 9. Communication Interface: Consider adding communication interfaces, such as UART, SPI, or I2C, for data exchange or remote control with computers or other devices.
4. Testing and Debugging: After completing the hardware and software design, perform system integration, testing, and debugging. Test the oscilloscope's performance by inputting different signal sources, adjust parameters, and resolve any potential problems to ensure the oscilloscope can accurately and stably display various types of waveform signals. 5. Summary: This simple oscilloscope provides an economical and practical way to observe and analyze analog signal waveforms, with good scalability and flexibility, allowing for functional expansion and improvement as needed.
