Abstract: A modular and miniaturized data recording module of NAND_FLASH controlled by STM32F103 is designed. The data recording module receives data such as failure modes and status information sent by airborne bus during the operation of aviation flight device through McBsp high-speed communication bus. After data processing, the effective data are stored. When needed, the upper computer can take out the data through the external interface of the system, and organize the data through software in time axis, modularization and graphics, so as to record the operation history of the system and analyze the operation status of the system. The data recording module reads and writes the data of storage module through USB and receives and verifies the data by issuing control instructions through RS232. Finally, the performance and reliability of the storage module are verified by the overall function test of the simulation system.
