摘要
TMS320C5510作为一种低功耗高性能的DSP处理器得到了广泛的应用,由于不提供异步串口,给它与其他异步设备之间的通信带来困难。文章给出了利用TMS320VC5510的缓冲同步串行口和DMA通道,通过对异步比特信号进行16倍过采样的方法实现RS232异步通信,着重说明了实现异步通信的工作原理、硬件连接结构及软件操作流程等,并给出了其在机载SAR天线稳定平台测试系统中的应用实例。该方法无需其他外部器件,硬件实现简单,程序流程简洁,提高了TMS320VC5510芯片使用的灵活性和通用性。
TMS320C5510 have been widely applied as a low-loss and high-performance DSP processor. Because no asynchronous surface provided, it＇s difficult to communicate with other asynchronous equipments. This article discusses the implementation of an asynchronous receiver and transmitter on a TMS320C5510 DSP using MeBSP, DMA and 16 over-sampling. It mainly explains the theory, software flow and hardware structure, and provides an example of application on test system for antenna stabilization platform of airborne SAR. This method can be implemented with easy program flow and no other equipment which extends the application of TMS320VC5510.
