DSP与FM25CL64接口驱动软件的实现

摘要

This paper provides a method for driver software design on TMS320F2812, which is used FRAM implement the data access interface. It mainly introduced the fi.mctional characteristics of DSP chip TMS320F2812 SPI module and FM25CL64 chip, as well as the driver software design of SPI module, memory and application interface. By sufficient test and initial application, driver software design advisability, flexible interface, can be able to meet the needs of the system.%本文给出了一种在TMS320F2812下，利用铁电存储器FM25CL64实现数据存取接口的软件设计方法。主要介绍了DSP芯片TMS320F2812SPI模块和FM25CL64芯片的功能特点，以及SPI模块、存储器、应用接口等各部分软件的设计。经充分测试和初步应用，驱动软件设计合理，接口灵活，能够满足系统要求。
