| 摘 要： | 给出了一种基于日本瑞萨公司SH_Mobile平台的SD卡存储方案。该方案首先介绍了SD卡的硬件电路设计,接着介绍了低层驱动程序的实现,重点对SD卡热插拔的中断控制以及插拔动作的去抖动处理提出了相应的解决方法。最后对SD卡采用的FAT16文件系统作出了详细的分析。该存储方案的有效性已得到了充分的验证,对其他类似的设计也具有很好的借鉴意义。

| Abstract: | The implementation of the SD card storage scheme are presented based on SH_Mobile platform of Renesas Technology Corp. Firstly, the hardware circuit is introduced briefly ,then the lower driver is provided, of which, the corresponding solutions for hot-Swappable interrupt control and debounce avoiding of the SD card are stressed. At last, the structure of FAT16 file system adopted by the SD card is analyzed in detail. The validity of this storage scheme is confirmed sufficiently, meanwhile, the hot-Swappable interrupt control and debounce avoiding also offer certain reference sense to similar designs. |
