Title The Design of Data Collection Based on TMS320F28335
Abstract
With the rapid development of information technology, signal processing technology has been widely applied. The signal acquisition as a signal source for the entire signal processing, its research will greatly optimize performance signal processing .Now, the advent of digital signal processing chip makes the whole signal processing undergone a qualitative change, making the fast Fourier transform FFT hardware implementation possible, greatly enhanced data acquisition and processing capabilities.DSP chip uses a Harvard architecture, with its powerful data processing capabilities in the areas of communications and signal processing has been widely used and has become a hot research.
This paper studies the development of TI`s new DSP chip TMS320F28335,so that it can achieve real-time signal acquisition system design requirements for low frequency signal acquisition. This paper describes the structure and function of TMS320F28335, and DSP development process of software and hardware used, including programming software and PCB system board CCS software Cadence, and produced PCB board .And we make a detailed description for how to use the ADC module in DSP chip to achieve data acquisition. The design and ideas as well as specific calls to settings for each register in ADC module is also included .We describe that the rest of the definition of data acquisition module used with the ADC module .And describes the DSP development of ideas, slim design and production process introduced TMS320F28335 based data acquisition system.
