[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0042] In the present application, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms “include”, “contain” or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the statement “including a…” does not exclude the presence of another same element in the process, method, article or device including the element.

[0043] In order to realize the debugging of each interface pin group on the control board and reduce the board area of the control board, another embodiment of the present application provides a debugging interface device, and the specific structure is as shown in Figure 1 The connection relationship between each device is specifically described as follows:

[0044] The single-interface side of the first multi-channel switch 30 is connected to the single-interface side of the second multi-channel switch 40 in sequence through the debugging interface 21 in the plug-in part 20 and the debugged interface 22.

[0045] In a specific example, the debugging interface 21 is a slot, and the debugged interface 22 is a plug.

[0046] In another specific example, the debugging interface 21 is a plug, and the debugged interface 22 is a slot.

[0047] The above two examples only show two implementation manners of the debugging interface 21 and the debugged interface 22, which are not specifically limited here and can be determined according to specific conditions and are within the protection scope of the present application.

[0048] The multiple interfaces of the multi-interface side of the first multi-channel switch 30 are respectively connected to the multiple interface pin groups 01 of the control board, Figure 1 For example, only three interface pins are arranged on the multi-interface side of the first multi-channel switch 30. The interface pin group 01 of the control board includes all pins of the control board for implementing one function, for example, the USB interface pin group of the control board includes all pins of the control board for implementing the USB function.

[0049] The multiple interfaces of the multi-interface side of the second multi-channel switch 40 are respectively connected to the multiple interface pin groups 01 in the debugging device, Figure 1 For example, only three interface pins are arranged on the multi-interface side of the second multi-channel switch 40. The interface pin group 01 in the debugging device includes all pins of the debugging device for implementing one function, for example, the USB interface pin group in the debugging device includes all pins of the debugging device for implementing the USB function.

[0050] The first controller 10 is connected to the control end of the second multi-channel switch 40. The first controller 10 is connected to the control end of the first multi-channel switch 30 in sequence through the debugged interface 22 and the debugging interface 21.

[0051] The controlled conduction channel in the first multi-channel switch 30 is the same as the controlled conduction channel in the second multi-channel switch 40. In the first multi-channel switch 30 and the second multi-channel switch, the channel refers to the circuit between the interface of the multi-interface side and the single-interface side of the corresponding multi-channel switch. If the circuit is controlled to form a path, it indicates that the channel is controlled to be conducted, and vice versa.

[0052] It should be noted that in actual application, an ESD (Electrostatic Discharge) protection device or other anti-static protection device is arranged on the single-interface side of the first multi-channel switch 30 to prevent static electricity from damaging the debugging interface device, the controller to be debugged and the debugging equipment.

[0053] In the debugging interface device, since the single-interface side of the first multi-channel switch 30 is connected to the single-interface side of the second multi-channel switch 40 through the plug-in piece 20, and the channel controlled to be turned on in the first multi-channel switch 30 is the same as the channel controlled to be turned on in the second multi-channel switch, the plurality of interface pin groups 01 of the control board in the controller to be debugged can be connected to the corresponding interface pin groups 01 in the debugging equipment, so that the debugging of each interface pin group 01 on the control board can be realized. In addition, since only one debugging interface 21 is arranged on the control board in the debugging interface device, the board area of the control board can be reduced. In summary, the debugging interface device provided by the present application can realize the debugging of each interface pin group 01 on the control board and reduce the board area of the control board.

[0054] It should be noted that, as known from the above, the debugging interface device can realize the debugging of each interface pin group 01 on the control board, so that the debugging during the initial debugging and the analysis of returned items for repair is facilitated, thereby reducing the difficulty of debugging and returned item analysis, and further facilitating problem analysis.

[0055] In addition, since the plug-in piece 20 is arranged in the debugging interface device, the signal quality of the high-speed signal of the high-speed interface pin group such as the DP interface pin group and the USB interface pin group on the control board is improved, so that the debugging of these interface pin groups can be realized.

[0056] Another embodiment of the present application provides another specific implementation of the debugging interface device, and the specific structure is shown in Figure 2 The second controller 50 is further included in the embodiment based on any of the above-mentioned embodiments, and the connection relationship between the device and other devices is specifically described as follows.

[0057] The first controller 10 is connected to the control end of the first multi-channel switch 30 through the debugging interface 21, the debugging interface 22 and the second controller 50 in sequence. The first controller 10 and the second controller 50 each have their own address, which is unique. When the two communicate, only the address matching can realize the communication, otherwise the communication cannot be realized.

[0058] Optionally, the second controller 50 is an I2C (I / O Expander for I2C Bus) expansion chip. In actual applications, the second controller 50 can be other types of controllers, which are not limited herein and can be determined according to actual conditions.

[0059] In the embodiment, since the communication between the first controller 10 and the second controller 50 can be realized only when the addresses of the two controllers match, the security of the debugging interface 21 is improved, and thus the security of the controller to be debugged is improved.

[0060] Another embodiment of the present application provides another specific implementation of the debugging interface device, which is different from the above embodiment in that:

[0071] In the present embodiment, since the connector 20 is a gold finger connector, the signal quality of the high-speed signals of the DP interface pin group and the USB interface pin group on the control board can be further improved, thereby reducing the influence of the signal quality of the high-speed signals on the debugging of these interface pin groups, and further improving the accuracy of the debugging of these interface pin groups.
