Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] On the basis of the above method, the present invention also provides a TF card that does not need to be driven to realize the Bluetooth function, such as figure 1 Shown, described system TF card 1 comprises:

[0032] TF card controller 13, TF card storage area 14, IO interface 12 and the bluetooth module 11 that is connected with described IO interface 12;

[0033] When the TF card 1 received the command of the operating system to access the Bluetooth module 11, the TF card controller 13 converted the data reading control command of the TF card storage area 14 into a control com...

Abstract

The invention provides a TF card capable of achieving the Bluetooth function without a driver and an achievement method of the TF card. The TF card is that a control instruction of a TF card controller to read and write data in a TF card storage area can be modified into a reuse instruction of accessing a Bluetooth module, the TF card controller can directly access the Bluetooth module after receiving the instruction of accessing the Bluetooth module, and therefore, the Bluetooth module of the TF card can be accessed through the operation system without additional driver, and as a result, the cost of design and manufacturing of the TF card is reduced while the functions of the TF card are increased.

Description

technical field [0001] The invention relates to the field of information communication, in particular to a TF card with bluetooth function without driving and a realization method thereof. Background technique [0002] In the prior art, the TF card driver of the operating system generally accesses the TF card through [0003] Send TF CMD through the TFIO interface to access the storage unit, the most common are the following four commands: [0004] Single sector (sector) read: CMD17; [0005] Multiple sector (sector) read: CMD18; [0006] Single sector (sector) write: CMD24; [0007] Multiple sector (sector) write: CMD25; [0008] These four commands take one parameter. Sector no (sector number). Indicates which sector of the storage unit is to be read or written. [0009] In general, if you want to access the Bluetooth module of TF COMBO, you need to add [0010] Add a new CMD. However, there is no such command in the standard driver, which means that the TF driver...
