基于MSP430的U盘设计
摘要
随着科学技术的快速发展,人们生活水平的提高,信息化程度的提高,信息的传输交换需求也就越来越多。在科学技术迅猛发展的今天,U盘已经成为了主流的数据储存产品,它满足了我们对数据储存的需求,实现了便携式移动存储、大大提高了办公效率,使人们生活更便捷。而且此装置小巧,方便携带,适用于各种场合,其应用前景和经济效益都很看好。因此,设计稳定、低功耗的数据储存器件就显得非常重要了。
本次研究设计的U盘是基于高速低功耗的MSP430单片机,采用串行外设协议总线结构对SD卡中的数据进行读写操作并通过USB接口与PC端进行数据传输,U盘内存2G,系统的功耗低,。整个系统的功能实现了U盘与电脑之间的通讯。这种方法简单、便于操作、综合成本较低,具有较大的推广应用价值。其中,因SD卡具有体积小、功耗低的优势,所以在本设计中采用SD卡作为储存器件。

The U disk design of a MSP430-based
Abstract
With the rapid development of science and technology, people living standard rise, the informatization degree rise, information exchange of transport demand is also more and more. In the rapid development of science and technology today, U disk has e the mainstream of data storage products, it satisfies our demand for data storage, implements the portable mobile storage, greatly improve the office efficiency, make life more convenient. And the device is small and portable, suitable for various occasions, the application prospect and economic benefit are look good. Design, therefore, stable, low power consumption of data storage devices is very important.
The study in the design of the USB flash drive is based on the high-speed low-power MSP430 MCU, using serial peripheral agreement bus structure on the data in the SD card read and write operations and through the USB interface with PC for data transmission, 2 g USB memory, system of low power consumption, power supply voltage of V. The function of the whole system has realized munication between usb puter. This method is simple, easy to operate, prehensive cost, has great popularization and application value. Among them, because the SD card with the advantages of small volume, low power consumption, so in this design using SD card as storage devices.
