摘要
本文基于一款ARM7芯片LPC2210实现对SD卡数据存储,并使用RAM作为数据的暂存区,当达到一个块的大小即512字节时,一次存入SD卡。首先对SD卡的特点作了简单的介绍,然后从接口设计和软件两个方面予以说明。
This paper is aimed to realize data storation with Secure Digital Card based on LPC2210, a kind of embedded CPU ofARM7. Meanwhile, RAM is used as a buffer. When the data's size is equal to 512 bytes, it will be stored in SD card at a time.Firstly, it presents a brief introduction about the characteristic of SD, and then accounts for design from interface design toprogramming.
