"基于STM32的多功能信号发生器设计与实现"

The paper describes the design and implementation of a multifunctional signal generator using STM32 as the core. The signal generator is capable of synthesizing various waveforms such as sine waves, square waves, and triangular waves. The STM32 serves as the main control unit, generating waveform data and sending digital signals to the digital-to-analog converter. The digital-to-analog converter converts the digital signals into analog signals, which are then transmitted to the operational amplifier for waveform output. The system also includes external buttons and potentiometers for waveform and frequency adjustments, as well as an LCD display for real-time visualization of waveform type, amplitude, and frequency. The paper provides a detailed explanation of the operational principles and software design process for the multifunctional signal generator. Key words: multifunctional signal generator, digital-to-analog converter, STM32 microcontroller.
