摘　　要：概要地介绍了TMS320F2812 DSP的基本性能,重点介绍了在Visual Basic 6.0下,利用MSComm控件实现上位PC机与下位机DSP之间异步串行通信的具体实现方式,并给出了一个采用RS-232串行通信标准来实现信息传输的实例。实验结果表明,串行通信简单,界面友好,改善了系统的性能,应用领域广泛。The article introduces the basic performance of TMS320F2812 DSP, then focuses on the realization of the asynchronism serial communication between PC and DSP with the control MSComm under Visual Basic 6.0. An example of using RS-232 serial communication standard to transfer information is given. The result shows that serial communication has the advantages of simple connection, friendly interface, improved system performance and broad applied fields.
