Research on information storing technology based on dual-TF card interface technology of MCU

The interface operating based on MCU reading and writing TF card was analyzed, a new operating method of dual-TF card based on MCU reading and writing on information storing and acquisition equipment was proposed, the initial procedure of electric reset of TF card was introduced. SPI sync serial interface bus was used to connect the dual-TF card and information reading and writing of TF card. High reliability of information storing operating on information storing equipment was satisfied.
