Serial Communication Based on TMS320F2812 and LabVIEW

Pan Qing-shan

Abstract

This paper introduces the principle of communication between the serial communication module of TMS320F2812 DSP and serial peripherals,and gives the asynchronous serial communication programming combined with actual application.According to the problem that it is hard to watch variables of power driving digital control systems,computed data by DSP are sent to PC through the serial port RS232.Thanks to using LabVIEW as the PC developing platform,data storage,data processing and data display are realized without extra hardware.Specific data analysis and processing can be achieved by the system,such as the FFT transform,harmonic analysis.Four way experimental waveforms of data generated by DSP displayed in LabVIEW are given out.
