| 摘 要： | 本文介绍了一种基于STM32F103ZET6的音频解码系统,利用MCU自带的FSMC接口外扩128M的nandflash,用于存储从PC机端拷贝的图片文件和音频文件。存储在flash中的文件利用FAT32文件系统进行管理,然后送LCD和wm8978进行图片显示和音频播放。音频解码芯片wm8978通过I2C和I2S分别和MCU通信,实现音频数据流的传输;LCD通过FSMC接口和MCU链接,实现图片数据流的传输。

| Abstract: | The paper introduces a kind of audio decoding system based on STM32F103ZET61].With the MCU FSMC interface,using the interface can expand external nandflash up to 128M,which used to store the copy image files and audio files.The files stored in flash use FAT32 file system to manage,and then sent LCD and wm8978 pictures to display or audio playback.Including,audio decoder chip wm8978 through the I2C and I2S respectively communicates with MCU,to realize audio streams of data transmission;FSMC interface and MCU links LCD,realized image data flow transmission. |
