摘要
TMS320F240是TI公司的TMS320C2x型16位定点数字信号处理器的DSP控制器,其外设异步串行通信接口因其结构简洁、使用方便,因而在DSP通讯中获得广泛的应用。文章简要介绍了TMS320F240的SCI电路的结构与工作原理,论述了一种通过DSP软件编程实现PC机与DSP间通讯的方法,并设计了通讯结果显示电路,实时监控数据的收发。此设计已通过实践检验,证明其方案可靠,具有很好的参考价值。
TMS320F240 is a 16 bit fixed-pointed digital signal processor controller, it is a member of TMS3202X series of TI. The serial communication interface （ SCI ）,one of peripherals of TMS320F240,has various applications in the design of DSP communication because of its simple struture and convenience. The paper simply introduces the structure of SCI, interprets a method of implementing communications between PC （ host ） and DSP （ slave ）,and designs a display circuit to examine data communication simultaneously. The method has been proved to be credible by practise and has good reference of relative works.
