【Abstract】 For the purpose of implementing the application of microcontroller in large-capacity data access,extended outside memory unit and porting file system can be used as a solution. This article presents the porting of the file system FatFs to a microcontroller STM32 based on ARM Cortex M3,and briefly describes the connection of the circuits and the compilation of FatFs bottom layer function.更多还原
