#Training Camp#Digital Oscilloscope

1. Description: A simple oscilloscope/signal generator, using a GD32 microcontroller as the main controller with on-chip ADC sampling. It also features an OLED screen and three control buttons for convenient display and operation.
2. Hardware Design:
1. Microcontroller: Uses a GD32 microcontroller as the main controller, providing sufficient processing power and rich library function support. 2. Analog Input: Receives external signals using analog input pins and converts analog signals to digital signals via an ADC (Analog-to-Digital Converter). 3. LCD Display: Uses a 128x64 pixel LCD screen for real-time waveform display. 4. Power Supply: Powered via USB, with an LDO circuit converting the power supply to the operating voltage required by the microcontroller and LCD.
3. Software Design:
1. Signal Acquisition: Writes GD32 standard library code, configures analog input pins, and uses built-in ADC library functions to sample and convert analog signals. 2. Waveform Display: Uses graphics library functions to draw waveform images on the LCD screen. Basic graphics drawing algorithms can be used. 3. Interface Design: Design a simple and intuitive user interface, allowing users to control the oscilloscope's operation via buttons or knobs, such as selecting the sampling frequency and adjusting the display range. 4. Signal Processing: Signal processing functions, such as filtering, peak detection, and spectrum analysis, can be added to enhance the oscilloscope's capabilities.
