本文设计了一种基于DSP的数据采集系统。该系统以TI公司的浮点DSP芯片TMS520F28555作为信号采集和处理的核心,用FFT技术对信号进行频谱分析。上位机利用VC6.O软件平台加2%.TeeChart控件,在该平台上实现信号波形显示与分析。
This paper we design a data acquisition system based on DSP, in which TMS320F28335 DSP is used as the data processing core and FFT technique is used for signal frequency domain analysis. The curve shows on the PC through the controls of TeeCharc in VC6.0.
