Design of DSP-based data acquisition program
Abstract: This paper describes the DSP-based data acquisition hardware used in the pin description of the preparation of the program is the programming language used, CCS development environment and a variety of hardware initialization method. This program is set up according to the sampling theorem the sampling frequency, and based on the TMS320C6713 development. TI provides for the TMS320 series of C language compiler. The standard C source file is compiled into a corresponding piece kind of become language source code files, and then assembled and linked to produce an executable object file. By setting the chamber to the control signal generator type, the signal frequency and the signal amplitude. At this point there will be signal input audio chip AIC23 input (use this chip can also be AD acquisition). Run write good program, can be observed to collect the received image data and display data stored in the DDataBuffer array is DDataBuffer image display array. By changing the source type to a different data collection DDataBuffer array.
