Peripheral device, writing fixture, and electronic device having the peripheral device

The present invention relates to an electronic device, and more particularly to an electronic device having a peripheral device.

In recent years, the development of electronic devices has been advancing by leaps and bounds, and its penetration rate has increased at an alarming rate year by year. In response to this e-news trend, the use of various electronic devices is becoming more and more connected. In order to satisfactorily achieve the connection between electronic devices, a standardized interface, such as RS-485, must be used.

The use of such a standardized interface also occurs in the connection of the electronic device to its peripheral devices (input and output devices). After the peripheral device is inserted into the electronic device (or called the host), the data is input into the host, or the data from the host is accepted. A cable connection is used between the peripheral device and the host. Among them, in addition to the compatibility of the mechanical structure must be considered, the consistency of the data transmission parameters between the host and the peripheral device must also be considered, and the latter is generally referred to as the communication protocol.

In the program in which the host is powered on, it is necessary to initialize the peripheral devices inserted in the host before the operating system is started, so that the operating system can access the data of the peripheral devices. Therefore, in the bus bar for connecting the host and the peripheral device, a plurality of identification pins are usually added, so that the host can identify the inserted peripheral device through the identification pin. However, adding identification pins requires increased manufacturing costs. In addition, if the host wants to recognize a wider variety of peripheral devices, the number of additional identification pins that need to be added is increased.

Therefore, an aspect of the present invention provides an electronic device having a peripheral device for causing a write jig to write corresponding information to a memory of a peripheral device according to a code obtained from an identification pin of the peripheral device. . When the peripheral device is connected to the host, the host drives the peripheral device based on the information stored in the memory.

According to an embodiment of the invention, an electronic device having a peripheral device includes a peripheral device and a host. The peripheral device includes a bus bar, a memory, an identification circuit, and at least one identification pin. The memory is electrically connected to the bus bar and has information about peripheral devices. The identification circuit generates code for the peripheral device. The pin electrical connection identification circuit is identified and disposed beside the bus bar. When the host and the peripheral device are electrically connected, the host obtains the information of the peripheral device from the memory through the bus bar, and drives the peripheral device according to the information of the peripheral device.

According to another embodiment of the present invention, a peripheral device includes a bus bar, a memory, an identification circuit, and at least one identification pin. The memory is electrically connected to the bus. The identification circuit generates code for the peripheral device. The pin electrical connection identification circuit is identified and disposed beside the bus bar. Wherein, when a write fixture electrically connects the bus bar and the identification pin, the write jig acquires the code of the peripheral device through the identification pin. Next, the writing jig acquires the information of the peripheral device according to the code of the peripheral device, and writes the information of the peripheral device into the memory through the bus bar. When the peripheral device is electrically connected to a host through the busbar, the host obtains information of the peripheral device from the memory through the busbar, and drives the peripheral device according to the information of the peripheral device.

According to still another embodiment of the present invention, a write jig includes a database, an acquisition module, and a write module. The writing fixture is used to electrically connect a peripheral device. The peripheral device includes an identification circuit, at least one identification pin, a bus bar, and a memory. The identification circuit electrically connects the identification pin to generate a code for the peripheral device. The bus is electrically connected to the memory. A database of writing fixtures stores information on several minimum inventory units. When the module is electrically connected to the identification pin of the peripheral device, the code of the peripheral device is obtained through the identification pin. The write module electrically connects the database and acquires the module. When the write module is electrically connected to the busbar of the peripheral device, the write module obtains information of the peripheral device from the information of the smallest inventory unit in the database according to the code of the peripheral device. Next, the write module transmits the information of the peripheral device to the memory of the peripheral device through the bus bar.

The application of the present invention has the following advantages. The same writing jig can write information of different peripheral devices into the memory of the peripheral device according to the connected peripheral devices. In this way, the same writing jig can be used to manufacture a plurality of different peripheral devices. In addition, there is no need to prepare a variety of different memories for different information in response to different peripheral devices. Therefore, when the memory is prepared, it is only necessary to classify the memory according to its hardware specifications, and it is not necessary to classify according to the contents of the burning on the memory, thereby reducing the time required for classification. Since the host system uses the memory of the bus from the peripheral device to obtain the relevant information for identification. Therefore, it is not necessary to add a pin to the busbar for connecting the peripheral device and the host, and is specifically used for transmitting identification information, thereby saving manufacturing costs. Further, when the device to which the peripheral device is connected is not written to the jig, the memory of the peripheral device is set to be write-proof, and the device stored in the peripheral device of the memory can be prevented from being changed by the device other than the jig.

Please refer to FIG. 1 , which is a functional block diagram of an electronic device with peripheral devices according to an embodiment of the invention. In an electronic device having a peripheral device, the writing jig writes the corresponding information to the memory of the peripheral device based on the code obtained from the identification pin of the peripheral device.

The electronic device 100 with peripheral devices includes a peripheral device 110 and a writing fixture 120. The peripheral device 110 includes a bus bar 111, a memory 112, an identification circuit 113, and at least one identification pin 114. The memory 112 is electrically connected to the bus bar 111, and the identification circuit 113 is electrically connected to the identification pin 114. The identification pin 114 is disposed beside the bus bar 111. Wherein, at least one measuring point can be applied as the identification pin 114. In addition, the memory 112 can be a flash memory, an electrically erasable programmable read-only memory (EEPROM), or other kinds of memory.

Identification circuit 113 generates code for peripheral device 110. The identification circuit 113 can generate the code of the peripheral device 110 by a combination of a high level and a low level. However, in other embodiments, the identification circuit 113 may also generate code for generating the peripheral device 110 by other means, and is not limited to the embodiment.

The writing fixture 120 includes a database 121, an acquisition module 122, and a writing module 123. The write module 123 is electrically connected to the database 121 and the acquisition module 122. The database 121 stores information of a number of Stock Keeping Units (SKUs). When the acquisition module 122 electrically connects the identification pin 114, the acquisition module 114 obtains the code of the peripheral device 110 through the identification pin 114. The acquisition module 122 can include at least one thimble 125 for lie on the identification pin 114 when the identification pin 114 is at least one measurement point. In this way, the accommodating module 122 can be electrically connected to the identification pin 114 by being connected by the ejector pin 125.

When the write module 123 is electrically connected to the bus bar 111, the information of the peripheral device 110 is obtained from the information of the minimum inventory unit in the database 121 according to the code of the peripheral device 110. Next, the write module 123 transmits the information of the peripheral device 110 to the memory 112 through the bus bar 111. In this way, the same writing jig can be used to manufacture peripheral devices of different minimum inventory units.

The write module 123 can include a bus bar connector 126 for connecting to the bus bar 111 of the peripheral device 110. Wherein, the identification pin 114 and the thimble 125 can be disposed at a specific position, so that when the bus bar connector 126 of the writing jig 120 is connected to the bus bar 111 of the peripheral device 110, the thimble 125 touches the identification pin of the peripheral device 110. 114. In this way, when the peripheral device 110 is electrically connected to the writing fixture 120, the bus bar 111 and the identification pin 114 need not be electrically connected to the writing jig 120, respectively.

In addition, since the information written in the memory 112 by the write module 123 is incorrect, the peripheral device 110 will not be recognized, and thus the peripheral device 110 cannot be driven. Therefore, the write module 123 can include a validator 124 for confirming whether the information of the peripheral device 110 in the memory 112 corresponds to the code of the peripheral device 110 generated by the identification circuit 113. The confirmer 124 can perform the step of confirming by querying the database 121 based on the information of the peripheral device 110 in the memory 112.

In order to prevent the information of the peripheral device 110 stored in the memory 112 from being lost, the peripheral device 110 may include a determining module 115 and an anti-writing module 116. The determining module 115 is electrically connected to the bus bar 111 and the identification pin 114 for determining whether the writing jig 120 is electrically connected to the bus bar 111 and the identification pin 114. The determining module 115 can determine that the connected electronic device is the writing jig 120 when an electronic device is electrically connected to the bus bar 111 and the identification pin 114. However, in other embodiments, the determining module 115 can determine whether the writing jig 120 is electrically connected to the bus bar 111 and the identification pin 114 by other means, and is not limited to the embodiment. The anti-write module 116 is electrically connected to the judging module 115 and the memory 112. When the writing fixture 120 is not electrically connected to the bus bar 111 and the identification pin 114, the anti-writing module 116 sets the memory 112 to be write-protected. In this way, it is possible to prevent the information stored in the peripheral device 110 of the memory 112 from being changed by the device written outside the jig 120.

Please refer to FIG. 2, which is a functional block diagram of an electronic device with peripheral devices according to another embodiment of the present invention. The electronic device 100 with peripheral devices includes a peripheral device 110 and a host 130. When the host 130 is electrically connected to the bus bar 111 of the peripheral device 110, the host 130 obtains the information of the peripheral device 110 from the memory 112 of the peripheral device 110 through the bus bar 111. Next, the host 130 drives the peripheral device 110 based on the information of the peripheral device 110. In this way, the bus bar 111 of the peripheral device 110 does not need to be provided with a pin for specifically transmitting the identification information, thereby saving the manufacturing cost of the peripheral device 110.

It will be apparent from the above-described embodiments of the present invention that the application of the present invention has the following advantages. The same writing jig can write information of different peripheral devices into the memory of the peripheral device according to the connected peripheral devices. In this way, the same writing jig can be used to manufacture a plurality of different peripheral devices. In addition, there is no need to prepare a variety of different memories for different information in response to different peripheral devices. Therefore, when the memory is prepared, it is only necessary to classify the memory according to its hardware specifications, and it is not necessary to classify according to the contents of the burning on the memory, thereby reducing the time required for classification. Since the host system uses the memory of the bus from the peripheral device to obtain the relevant information for identification. Therefore, it is not necessary to add a pin to the busbar for connecting the peripheral device and the host, and is specifically used for transmitting identification information, thereby saving manufacturing costs. Further, when the device to which the peripheral device is connected is not written to the jig, the memory of the peripheral device is set to be write-proof, and the device stored in the peripheral device of the memory can be prevented from being changed by the device other than the jig.
