TMS320C6711 DSP异步串行通信的研究与实现

Implementation of Asynchronous Serial Communication on TMS320C6711 DSP

分析了异步串行通信的特点及其数据帧结构,提出了采用过采样的方法,结合使用扩展的直接存储器存取(EDMA),利用高速同步串口模拟异步串口功能,从而在TMS320C6711DSP中实现异步串行通信。论述了McBSP过采样的原理、硬件配置和软件实现。

UART and its Discusses the characteristic of data packet, the MeBSP and chronous serial Metho and so Of Over EDMA to describes how to use implement the asyninterface through oversampling. sampling, hardware configuration ware realization are dealt with in detail.
