Abstract
At present, a single-chip microcomputer without an operating system is used for data exchange with single storage media and the transmission speed is limited. In this paper, FATFS module is transplanted on a single-chip microcomputer based on an ARM Cortex-M7 micro-controller. The data acquisition and storage are carried out in parallel with multiple storage media such as SD, the NAND FLASH and the U disk on a high-performance STM32H7 platform. The read-write speed is tested finally. The results show that the file management function can be completed well and the operation is stable.
