摘要
本文针对国内市场应用广泛的TMS320F2812型DSP以及RS485标准,介绍了DSP的异步串行通信接口SCI,RS485/RS232的接口转换电路以及VB的MSComm串口通信控件,并设计了DSP串口模块工作在FIFO模式下与上位机的远程通信系统,该设计方案的可行性和可靠性已经得到了实验验证。
In the domestic market,TMS320F2812 DSP and RS485 serial communication are widely used.In this paper, the writer explain DSP＇s SCI module,RSa32/RS485＇s interface converter circuit and VB＇s serial communication controller.The writer also design a telecommunication system used between DSP and PC,when the SCI working under the FIFO mode.The feasibility and reliability of this program has been verified by experiments.
