嵌入式存储卡接口电路及驱动程序设计

his paper discusses the design process of the SD memory card to read and write operations based on the single-chip control unit,realize the block reading and block writint of the data on the SD card, reading and writing of data files, as well as the data display with the LCD. The system as a generic SD card reader controller, at the same time with the keyboard, display interface circuit are used for general industrial applications operating on the memory card, as well as the demand for man-machine conversation function. the sytem can also control the operation of the object with the rich potential use of SCM, so the design of the system have good application prospects.
