摘要
介绍了一种基于TMS320LF2407数字信号处理器(DSP)的数据采集、处理和通讯系统。该系统充分利用了DSP芯片具有的高速高性能处理能力,以及它内部集成的两个事件管理模块EVA和EVB,并与光电编码器组成电机转速测定仪器,可直接测定电机的转速。通过它内部集成的串行通讯接口(SCI)模块与计算机之间进行的数据传输可以实时地在计算机终端上显示出来,电平转换芯片接口芯片使用美国MAXIM公司的MAX3221。实验结果表明了该设计方案的可行性。
A data acquisition, processing and communication system based on DSP TMS320LF2407 is introduced .An instrument of measuring the velocity of motor is consisted of abovementioned system and photoelectricity encoder.High speeding and high performance DSP chip and Internal integrated EVA and EVB module are used to measure motor velocity and location in this system. Data transmission between internal integrated serial communication interface （SCI） and computer can be displayed on the upper computer in real time, Level transformation chip interface chip is MAX3221 made by MAXIM company. Feasibility of above design solution is proved through the result of experiment .
