Design of Data Acquisition System Based on AD7367 and TMS320F2812

摘要

With the development of servo system, the data acquisition system demands higher sampling accuracy and higher transmission speed. To used in motor servo control application, a data acquisition system based on AD7367 and TMS320F2812 is developed in this paper. The hardware design develops the hardware platform of the data acquisition system, while the software design provides inquiry mode and interrupt mode two methods to collect the conversion result. The McBSP of TMS320F2812 is compatible with SPI when configured in clock stop mode. The AD7367 whose serial interface is compatible with SPI interface is fit to use in data acquisition of motor control. The experiment results show that the data acquisition system with plain hardware structure can assure the sampling accuracy and the transmission speed.
