用stm32做的SD读卡器源码，插入usb识别为可移动磁盘，利用SPI1操作SD卡-Use the stm32 do SD card reader source, the use of the the SPI1 operating SD card as a removable disk, insert the usb recognition

基于STM32的USB做成的SD卡U盘读卡器，采用SDIO模式-Made based on the STM32 USB SD card U disk reader, using the SDIO mode

利用一块奋斗版STM32开发板的SD卡及USB接口实现板上的U盘功能-Use a hard version of STM32 development board SD card and USB interface board U disk function

基于STM32的的u盘开发，该项目有两个功能： 1.能够将128的NAND FLASH 当做U盘用，将USB插上电脑后就能识别！ 2.可以当做读卡器用，插上SD卡后，能后在电脑上显示SD卡-Based on the STM32 USB development, the project has two functions: 1. To be able to use 128 NAND FLASH as u disk, USB plug in computer after identifyin
