| Abstract: | This paper introduced the connection between C8051F015 and MMC via SPI interface. C function collection about FATI6 basic file opteration was realized after the analysis of the MMC read/write mechanism and the FAT characteristics. The collection provided bottom support of memory expansion on MCU which have been embedded in SPI interface. |
