"STM32嵌入式WAV音频播放器设计与实现"
ABSTRACT In today's increasingly digitized world, digital audio technology has become one of the most widely used digital technologies. This paper explores the basic principles of digital audio technology through the development of a WAV digital audio player based on the STM32 microcontroller. Following the basic process of embedded system development, the paper analyzes the requirements for the player's functionality, designs, and implements a complete WAV digital audio player. The paper also discusses the porting of the FATfs file system, enabling the decoding and playback of audio data from high-capacity SD cards with FAT file systems. Additionally, the use of a double-buffering work mode addresses the coherence issues when reading and playing audio data from SD cards. Finally, the completed digital audio player undergoes system testing, achieving the expected goals. Keywords: digital audio, STM32, WAV, FATfs, double buffering.
