The present invention provides a kind of data storage method based on STM32F103ZET6 and eMMC card, adopts STM32F103ZET6 single-chip microcomputer of ST Company, utilizes SDIO module and eMMC card cross-linking, realizes the generation of clock and the transmission of order and data, SDIO interface mounts eMMC card, It is used for data storage and completes the interface driver software design. The single-chip microcomputer adopted in the present invention has high performance, low cost, low power consumption, and rich interfaces. The eMMC card has the advantages of small size, large storage capacity, fast reading and writing speed, and long service life. The maximum rate can reach 416Mbps. ST company provides a large number of open Based on the open software library, interface-driven software development is carried out, which shortens the research and development cycle. At the same time, because the software library is a standard database, the interface-driven software developed on the basis of the standard database can be easily transplanted to other models; custom data format , The file system is shielded, which greatly shortens the development cycle. Since there is no file system, the reliability of the storage is higher during use.
Description
technical field [0001] The invention relates to the technical field of embedded data storage, in particular to a data storage design method, which can be applied to mobile phones, portable mobile storage devices and other military and civilian data storage devices. Background technique [0002] In the embedded field, single-chip microcomputer has become the first choice for learning, application and development due to its advantages of small size, light weight, low price and concentrated functions. STM32F103ZET6 single-chip microcomputer is an ARM Cortex-M3 core processor specially designed for embedded applications requiring high performance, low cost, and low power consumption. It is currently the most widely used single-chip microcomputer. Many single-chip microcomputers require large-capacity storage devices to store data, which requires the single-chip microcomputer to have a large-capacity storage function. The design of data storage devices based on single-chip micro...
