摘要
文章介绍了一种基于Cortex-M3处理器的信号采集系统,详细阐述了STM32F103RC系列32位处理器实现片内A/D转换、USB通信及信号调理等电路设计的技术要点。利用片内D/A模块设计了一个回放接口,以便实时观察实际采集到的信号。
In this paper,a signal acquisition system based on Cortex-M3 processor was introduced.And some technical points in circuit design are also presented in details,such as implementation of inner A/D conversion,USB communication and signal processing.Inner D/A module has been used to design an output interface.Therefore it would be easier to observe the input data in real-time.
