weiweizsz_30000

SD卡阅读器参考设计可以让用户通过全速USB模块系统在?SD Card里读写PC或USB主机存储的文件。The SD Card interface is based on SPI protocol. Mass Storage Device class is used to implement the high level communication between the host application and data memory.The SD Card reader reference design shows how easy are to interface a SD Card to an 8 bit microcontroller with a SPI module. This design is an alternative Flexis JM family development board; The user can exchange a MCF51JM128 for a MC9S08JM60 (pin to pin compatible). It includes two user LED’s, one button and one expansion header that allows users to access other microcontroller peripherals like SPI, RGPIO, etc.
