| 摘 要： | 针对传统方法中"单片机(MCU)读写SD卡数据时需要执行复杂的文件分区表数据操作"的缺点,以LED护栏管显示屏技术要求为例,提出了一种单片机主从系统中快速、简单的SD卡存储器的访问方法,并给出了一种实用的SD卡与单片机连接的接口电路.采用该方法读取SD卡控制数据与存储文件的分区表格式无关,因此支持FAT32、NTFS、...

| Abstract: | In order to reduce the difficulty of secure digital memory card operation in microcontroller unit（MCU） system,a simple SD card driven method and interface circuit was introduced.This method is independent of partition table,so it sustains all kinds of SD card and partition formats,including FAT32,NTFS,exFAT format from 16 MByte to 32 GByte SD card.It can be appropriate for Master-slave control system using SD card.This method was used in LED display controller system.The application results indicate that the system achieves good effect. |
