文章设计了一种基于STM32F103RCT6微控制器以及VS1003B解码芯片的无线解说器。采用意法半导体的Cortex-M3内核的STM32系列作为核心控制芯片管理及读取解说词文件,并将这些数据发送给VS1003B进行解码,同时接收外界命令。系统采用大容量的SD卡作为存储部分,通过SPI将VS1003B与SD卡的数据与STM32进行交互通信。本解说器在播放时没有出现理论上的断续情况,音质较好,占用的软硬件资源也较少,为后续的扩展留下了很大空间。

This paper designs a wireless interpretation device based on the STM32F103RBT6 microcontroller and VS1003B decoder chip. The STM32 series using Cortex-M3 core from STMicroelectronics is used to manage and read commentary data, and send the data to the VS1003B being decoded while receiving an external command. The system uses high-capacity SD card as the storage part, and carries out communication between the data from VS1003B and SD card with the STM32 via SPI. This device does not appear theoretical interruption when playing, and has better voice quality and less software and hardware resources occupied, leaving a large space for the future expansion.
