| 摘 要： | 介绍利用ATmega64L单片机实现铁电存储器FM24C256中的数据向SD卡传输与存储的方法。首先利用上位机操作系统完成SD卡文件系统的构建,并将预先建立的.txt文件顺序复制到SD卡中;然后利用ATmega64L单片机同时具备TWI和SPI接口的优势,通过铁电存储器和SD卡的底层读写函数,将存储在铁电存储器中的数据传输到SD卡并保存在相应的.txt文件中。

| Abstract: | A method of transmitting and saving data from FM24C256 to SD card is presented by using ATmega64L MCU.The FAT32 file system is established in SD card by Windows operating system on PC,and then the pre-established.txt files are copied to SD card in turn.Based on the advantage of the TWI bus and SPI bus in ATmega64L,the data stored in FM24C256 are transmitted and saved in the corresponding.txt files in SD card through lower-level read and write functions of FM24C256 and SD card. |
