基于DSP串行通信接口开发的研究

Research on Development of Serial Communication Interface Based on DSP

数字信号处理器(DSP)在实际应用中经常通过串口进行通信,因而在DSP中往往会集成相应的模块。以TI公司的TMS320F2812为平台,介绍了其上的SCI模块接口,并给出了基于查询、中断和FIFO这3种方式下SCI模块串口通信的具体开发流程。最后给出了基于FIFO中断模式的具体开发案例,为实际开发提供了借鉴和帮助。

Digital signal processor( DSP) often communicates through serial port in practical application.Therefore,the corresponding modules are often integrated in DSP. Based on the TMS320 F2812 of TI company as a platform,this paper has introduced the SCI module interface,and gives three modes which are query,interruption and FIFO for the serial communication of SCI module in the development. Finally,a specific development case based on FIFO interrupt mode is given,which provides reference and guidance for the actual development.
