| 摘 要： | 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。

| Abstract: | This paper designs a wireless interpretation device based on the STM32F103RBT6 microcontroller and VS1003 B 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 VS1003 B 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 VS1003 B 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. |
