摘要：

介绍了基于TMS320F28335测斜仪系统信号处理板的设计与实现。概述了TI公司TMS320F28335的功能特性和部分外围接口、信号处理板的基本硬件结构及具体功能应用;分析了系统的软件结构、各个模块软件的具体实现方式。整个系统,完成了从模拟信号采样到DSC数字信号处理以及EEPROM的读写和上位机通信过程。利用TMS320F28335的中断技术,实现了各个功能模块分别在各自的中断线程中正常运行,而不会引起相互间的干扰,造成系统混乱。

Abstract:

This report introduces the design and realization of digital signal processing board of Deviation Surveying Instrument based on TMS320F28335.The functional properties and some periphery connection of TMS320F28335 DSC made by TI Company are outlined,the specific function application and basic hardware structure of the signal processing board are described,and the whole system software structure and specific implementation of specific software modules are analyzed.The whole system realizes the sampling of the analog signal,DSC digital signal processing,EEPROM's reading and writing and communication with upper computer.Using the interrupt technology of TMS320F28335,every functional module can normally run in its own interrupt thread without mutual interference,thus avoiding the system chaos.

Key words: DSC;TMS320F28335;AD7656
