Description

Method for controlling peripheral device through data storage device and data storage device for controlling peripheral device

The invention relates to the technical field of electronic peripheral products, in particular to a method for controlling peripheral devices through a data storage device and a data storage device for controlling peripheral devices.

With the development of electronic technology, users have more and more requirements for additional functions of computers or electronic products. Therefore, various peripheral devices are correspondingly designed and developed, such as: tablet, printer, label machine, Speakers, portable hard drives, flash drives, game joysticks, CD players, wireless network cards, and digital cameras. As shown in the perspective view of the computer mainframe shown in FIG. 1, various input/output (I/O) interfaces are integrated into the motherboard in order to enable the central processing unit in the mainframe to operate the peripheral devices. Above. Early, Firewire (IEEE-1394), Universal Serial Bus (USB), Serial Data Communication Interface (EIA-RS-232, RS232), Parallel Port, Parallel Port, Ethernet The Ethernet interface (RJ45) is often an indispensable input/output interface for computer mainframes; however, with the rapid development of computer technology and portable electronic devices, it can support Plug-and-Play (Plug-and-Play, The communication interface of PNP) has gradually become the mainstream of I/O interface between electronic products, such as: USB interface, Parallel advanced technology attachment (PATA), Serial ATA interface (SATA), ISA interface. (Industry standard architecture, ISA).

The Universal Serial Bus (USB) supports hot-swap and plug-and-play features that make it easy to connect a host computer with a laptop to a peripheral device with a USB interface. When a USB peripheral device is coupled to the host computer, the operating system performs a USB Enumeration on the USB peripheral device. Taking Microsoft's Windows operating system XP (Windows XP) as an example, the enumeration program includes the following steps: (S1'): The Windows operating system initializes the USB peripheral device, and presets a device address of the USB peripheral device to 0. (S2'): The Windows operating system requires the USB peripheral device to reply to a device description (Device Descriptors) with a total length of 64 bytes; (S3'): reset the USB peripheral device and send a set address command (Set Address Command) to the USB peripheral device, and then give a USB peripheral device a device address; (S4'): The Windows operating system requires the USB peripheral device to reply to the device description information with a total length of 18 bytes to know the basic information of the USB peripheral device. For example, Vendor ID (VID) and Product ID (PID); (S5'): The Windows operating system requires the USB peripheral device to reply to a Configuration Descriptors to know the USB peripheral device. Interface number (bNumInterfaces); (S6'): Windows operating system requires USB peripheral device to reply to interface description information (Interface Descriptors) to know the USB peripheral device Number of endpoints (bNumEndpoints); (S7'): The Windows operating system requires the USB peripheral device to reply to the Endpoint Descriptors to know the data transfer mode (bmAttributes) of the endpoint; and (S8'): The driver for the USB peripheral device is automatically installed in the operating system (the user must download the driver and install it manually if necessary).

As is familiar to engineers familiar with the design and manufacture of peripheral devices, other operating systems, such as Apple's iOS system, Apple's MAC system, Google's Android system, or Linux operating system, may not use the enumeration procedures. It will be identical to the enumeration steps (S1')-(S8') described above. In addition, for the USB peripheral device, the vendor may only develop a driver compatible with the Windows operating system, and the development is compatible with the iOS system, the MAC system, the Android system, and/or the Linux operation. The driver for the system. For this reason, some commercially available USB peripheral devices can only support computer hosts that install a specific operating system. Therefore, how to make USB peripheral devices compatible with various operating systems has become the biggest issue for USB peripheral device suppliers.

U.S. Patent No. 7,921,244 discloses a USB peripheral device. According to the architecture diagram of the USB peripheral device shown in FIG. 2, we can know that the USB peripheral device 1' is a data storage device, and includes: a microprocessor 11', a first USB unit 12', and a second The USB unit 13' is connected to a storage unit 14'; wherein the first USB unit 12' is connected to a first USB interface 21' of a first host 2', and the second USB is The unit 13' is connected to a second USB interface 31' of a second host 3'. In this manner, the first central processing unit 22 ′ in the first host 2 ′ can be accessed and stored in the storage unit 14 ′ through the input/output channels established by the first USB interface 21 ′ and the first USB unit 12 ′. Similarly, the second central processing unit 32' in the second host 3' can also be accessed and stored in the storage through the input/output channels established by the second USB interface 31' and the second USB unit 13'. Information within unit 14'.

It should be noted that a large number of drivers are stored in the storage unit 14' of the USB peripheral device 1', and an automatic installer is embedded in the register of the microprocessor 11'. In this way, after the first host 2' or the second host 3' completes the enumeration process (USB Enumeration) of the USB peripheral device 1', the automatic installer immediately finds among the large number of drivers. a driver compatible with the operating system of the first host 2' or the second host 3', and then storing the driver to the first storage device 23' and the second host 3' in the first host 2' Second, the storage device 33'; finally, the automatic installer automatically installs the compatible version of the driver in the first host 2' and the second host 3' operating system.

Engineers familiar with the design and manufacture of peripheral electronic devices can quickly find that U.S. Patent No. 7,921,244 is solved by storing all drivers compatible with various operating systems in the USB peripheral device 1'. The compatibility of the USB peripheral device 1' in different operating systems; however, the solution proposed by US Pat. No. 7,921,244 shows many drawbacks in practical applications: (1) Due to a large number of drivers The storage unit 14' occupying the USB peripheral device 1' (ie, the data storage device) has too much memory space, causing damage to the end user rights of the USB peripheral device 1'. In more detail, it is assumed that the USB peripheral device 1' purchased by the terminal user should theoretically have 4 GB, but in reality, only 3.5 GB may be left. (2) On the other hand, if the USB peripheral device 1' has a non-USB unit such as an RS-232 interface or a SATA interface, the user connects the USB peripheral device 1' to an RS-232 interface or a SATA interface. After the host, it downloads itself and installs the relevant drivers in the host's operating system. It is conceivable that the peripheral device supplier cannot pre-store the driver of the non-USB interface compatible with the various operating systems in the storage unit 14' of the USB peripheral device 1'.

Based on the above reasons, the inventors of the present invention have tried their best to study the invention, and finally developed a method for controlling the peripheral device through the data storage device and a data storage device for controlling the peripheral device.

In this way, the host only needs to change or edit the content of the operation data file stored in the control device of the peripheral device of the data storage device, so as to achieve the purpose of operating the peripheral device. Therefore, the developer of the peripheral device only needs to develop the driver of the data storage device and a specific operation data access program for accessing the operation data file, and does not need to simultaneously develop and be compatible with the Windows operating system and the iOS system. , MAC system, Android system, peripheral device driver with Linux operating system.

Before beginning to explain a data storage device for controlling a peripheral device of the present invention, it is necessary to introduce a file system for assisting the data storage device to systematically organize and configure data. FAT is a well-known file system developed by Microsoft and called the File Allocation Table. It is worth noting that the FAT can be further classified into FAT12, FAT16, FAT32, and exFAT (FAT64) according to the maximum separable disk volume. Unlike the various FAT file systems developed by Microsoft based on the file allocation table, the Linux camp also proposes the so-called Extended file system (ext). Of course, in addition to the file system mentioned above, other file systems such as NTFS, HFS+, etc. are also included.

Please refer to Figure 3, which shows the architecture of the FAT file system. As shown in FIG. 3, the FAT file system plans a main boot area F1, a file allocation table F2, a directory F4, and a data storage area F5 in a data storage unit of a data storage device.

In the first embodiment, the data storage device 1 of the controllable peripheral device has only a single communication interface, and a memory card having a card-edge board connector is an exemplary embodiment thereof. Moreover, the peripheral device 2 is a display (electronic photo frame). The data storage device 1 (memory card) is mainly used for storing some stored picture data and video data for display by the display. In the first embodiment, the present invention also utilizes the data storage device 1 to store some parameter setting data of the peripheral device 2.

As shown in FIG. 6 and FIG. 7, the data storage device 1 (memory card) of the controllable peripheral device of the present invention comprises: a micro processing unit 11, a first communication unit 12 (gold finger electrode) and a storage unit 14, The first communication unit 12 is coupled to the micro processing unit 11 and is configured to connect to the first communication interface 21 (memory card slot) of the peripheral device 2. On the other hand, the peripheral device 2 is connected to the host device 3 of the user terminal by its second communication interface 22.

The operating data file in the peripheral device control block 142 is modified to modify some parameter values of the peripheral device 2 (lens device), such as exposure value, color, white balance, etc., to achieve the peripheral device 2 in this manner. Operational control. On the other hand, the operating system 32 of the host 3 can see many raw images that have not been processed or transferred after the data storage device 1 is turned on, for example, original image files such as camera_4K.bmp, camera_8M.bmp, and the like. At this time, the operating system 32 of the host computer 3 can open the original image files by using the image editing software.

Please refer to FIG. 10, which is a perspective view showing a data storage device of the controllable peripheral device of the present invention; and, referring to FIG. 11, a internal architecture diagram of a data storage device capable of controlling peripheral devices. 10 and FIG. 11, an exemplary embodiment of the data storage device 1 of the controllable peripheral device is a flash drive having a USB communication interface and a serial port terminal; The peripheral device 2 is a label printer. As shown in FIG. 10 and FIG. 11, the data storage device 1 of the controllable peripheral device of the present invention comprises a micro processing unit 11, a first communication unit 12 (serial port terminal), and a second communication unit 13 (USB interface). And a storage unit 14 , wherein the first communication unit 12 is coupled to the micro processing unit 11 and is configured to connect a first communication interface 21 (serial port terminal) of the peripheral device 2 . On the other hand, the second communication unit 13 is also connected to the micro processing unit 11 and is used to connect the input/output interface 31 (USB interface) of the host 3.

The second embodiment will be described in more detail. After the input/output interface 31 (USB interface) of the host 3 establishes communication with the second communication interface 22 (USB interface) of the peripheral device 2, the host computer 3 can find the serial.io file after the data storage device 1 is turned on. Next, the data storage block 141 storing the serial.io file is set or defined as a so-called peripheral device control block 142. Further, the operating system 32 of the host 3 can use the editing software to open the serial.io and modify its contents. Thereafter, the central processing unit 20 in the peripheral device 2 (labeler) drives the labeling machine to perform a corresponding action according to the content of the serial.io, for example, printing a receipt (Receipt).

Briefly, as long as the method for controlling the peripheral device through the data storage device is applied, the application system 32 of the host computer 3 does not need to install any application for driving the labeling machine, but only needs to access the data storage device. The operation data file (ie, the serial.io file) of the labeler stored in 1 can be directly communicated with the peripheral device 2 (labeler). Obviously, the novel peripheral device control technology provided by the present invention exhibits many advantages, including: (1) The developer of the peripheral device only needs to develop the driver of the data storage device 1 and to read or change the storage device to be controlled by the peripheral device. The "Operational Data Access Program" of the contents of the operation data file in the block 142 does not need to simultaneously develop a Windows operating system (Windows) compatible with Microsoft, Apple's iOS system, and Apple's Macintosh system. , Google's Android system, and peripheral device drivers for the Linux operating system. (2) On the other hand, the terminal user can easily control any of the peripheral devices 2 by simply using the data storage device 1 and installing a corresponding operation data access program in the operating system 32 of the host computer 3.
