基于TMS320C6416T DSK的McBSP和EDMA模拟异步串口

McBSP and EDMA Analog Asynchronous Serial Port Based on TMS320C6416T DSK

TMS320C6416T因其高性能及强大的数据处理能力,在通信和信号处理、自动控制等领域得到了广泛的应用,但其所提供的同步串口并不支持通用异步串行收发器标准。笔者设计了一种利用片上同步多通道缓冲串口和增强型直接存储器存取实现异步串口通信的方案。该方案解决了C6416T芯片只有同步串口而不能进行异步传输的问题,丰富了接口功能,为调试和实际应用提供了方便。

Because of its high performance and powerful data processing ability,TMS320C6416T is widely used in communication,signal processing and automatic control.However,the serial port provided by C6416T is synchronous serial port,which does not support UART standard.In this paper,an asynchronous serial communication scheme based on McBSP and EDMA is designed.This scheme solves the problem that C6416T chip only has synchronous serial port but can not carry out asynchronous transmission,enriches the interface function,and provides convenience for debugging and practical application.
