[0029] In view of the technical problems raised by the background technology, the present application provides a switching device and system for controller debugging, which can reduce the number of plugging and unplugging of display screens and peripheral interfaces, and can flexibly switch the connection relationship between the display screen and different peripherals and multiple controllers to be debugged, thereby improving debugging efficiency.

[0030] See the instruction manual Figure 1 And the instruction manual Figure 2A switching device for controller debugging provided in one embodiment of the present application is mainly composed of a shell and a circuit board arranged inside the shell, wherein the shell is a rectangular parallelepiped structure, and a plurality of HDMI input interfaces are arranged at intervals on the front panel of the shell along its length direction; an HDMI output interface is arranged on the first side surface of the shell adjacent to the front panel; a plurality of USB input interfaces are arranged at intervals on the rear panel of the shell along its length direction; a USB output interface is arranged on the second side surface of the shell opposite to the first side surface; an HDMI switching button and a USB switching button are arranged on the upper panel of the shell; an HDMI switching chip and a USB switching chip are arranged on the circuit board, an input pin of the HDMI switching chip is connected to a plurality of the HDMI input interfaces, an output pin thereof is connected to one of the HDMI output interfaces, and a control pin thereof is connected to the HDMI switching button; an input pin of the USB switching chip is connected to a plurality of the HDMI input interfaces, an output pin thereof is connected to one of the USB output interfaces, and a control pin thereof is connected to the USB switching button.

[0031] Among them, the multiple HDMI input interfaces are respectively connected to different controllers to be debugged, and one HDMI output interface is connected to a display screen. The connection relationship between the multiple HDMI input interfaces and the one HDMI output interface is switched by the HDMI switching button, so as to select a target controller to be debugged from different controllers to be debugged and connect to the display screen, and then output the screen of the target controller to be debugged to the display screen for display; the multiple USB input interfaces are connected to different peripherals (mouse, touchpad, etc.), and one USB output interface is connected to a target controller to be debugged. The connection relationship between the multiple USB input interfaces and the one USB output interface is switched by the USB switching button, so as to select a target peripheral from different peripherals and connect to the target controller to be debugged, and then debug the target controller to be debugged according to the display content on the display screen.

[0032] The HDMI switch chip is of the MS1826A type, which includes four independent HDMI audio and video input channels and one HDMI audio and video output channel; the USB switch chip is of the MAX4946 type, which is a four-channel USB 2.0 high-speed analog switch, and each channel can be switched independently. The working principles of the two chips should be well known to those skilled in the art, and will not be described in detail here.

[0033] Furthermore, in order to better prompt the user which controller to be debugged is selected as the target controller to be tested, and which peripheral is selected as the target peripheral, LED indicators are connected in series between the input pin of the HDMI switch chip and the multiple HDMI input interfaces, and between the input pin of the USB switch chip and the multiple USB input interfaces, and the LED indicators are installed above each HDMI input interface on the front panel of the shell, and above each USB input interface on the rear panel of the shell. During use, the LED indicator above the HDMI input interface corresponding to the target controller to be tested, and the LED indicator above the USB input interface corresponding to the target peripheral will light up; while the LED indicators above the remaining HDMI input interfaces and the LED indicators above the remaining USB input interfaces will go out.

[0034] In addition, in this application, the front panel of the shell is also provided with a power interface for providing working power for the HDMI switch chip and the USB switch chip. However, the power interface is generally connected to a DC5V power supply, while the working power supply of the HDMI switch chip and the USB switch chip is DC3.3V. Therefore, a voltage regulator chip connected to the power interface is also provided on the circuit board for converting the DC5V power supply connected to the power interface into DC3.3V. Figure 3 In one embodiment, the model of the voltage stabilizing chip is RT8010PQW1, the DC5V power supply externally connected to the power interface is grounded via the first capacitor C1, the EN pin and the VIN pin of the voltage stabilizing chip are both connected between the DC5V power supply and the first capacitor C1, so as to use the DC5V power supply as the input voltage of the voltage stabilizing chip; its GND pin is directly connected to the digital ground DGND, its FB pin is connected to the first voltage-dividing resistor R1 and the second voltage-dividing resistor R2 directly in one path, and is connected to the other end of the second voltage-dividing resistor R2 via the third capacitor C3 in the other path; its LX pin is connected to the other end of the third capacitor C3 via the first inductor L1. The resistance of the first voltage-dividing resistor R1 is 110KΩ, the resistance of the second voltage-dividing resistor R2 is 510KΩ, and the first voltage-dividing resistor R1 is directly connected to the digital ground DGND. The output voltage Vout is drawn from the second voltage-dividing resistor R2, wherein Vout=Vref*(1+R2 / R1), and the basic voltage Vref is a determined value of 0.6V. Then, Vout can be calculated to be 3.3V, which is used as the working power supply for the HDMI switching chip and the USB switching chip.

[0035] During use, first connect the power interface of the switching device to a DC5V power supply, connect the HDMI output interface to the display screen through a first wiring, connect the USB input interface to different peripherals through multiple second wirings, connect the HDMI output interface to different controllers to be debugged through multiple third wirings, and then control the HDMI switching button by pressing to select the target controller to be debugged (the corresponding LED indicator lights up), and then the screen of the target controller to be debugged is output to the display screen for display; then connect the USB output interface to the target controller to be debugged through a fourth wiring, and control the USB switching button by pressing to select the target peripheral (the corresponding LED indicator lights up), and then operate the target peripheral to debug the target controller to be debugged according to the screen displayed on the display screen.

[0036] It can be seen that the switching device for controller debugging provided by the present application only needs to control the HDMI switching button or the USB switching button when switching the target controller to be debugged or the target peripheral device, and in the switching process, only the third wiring needs to be unplugged from the current target controller to be debugged and inserted into the target controller to be debugged to be switched, and the first wiring connecting the HDMI output interface and the display screen, the multiple second wirings connecting the USB input interface and different peripheral devices, and the multiple third wirings connecting the HDMI output interface and different controllers to be debugged remain unchanged. This overcomes the problem of frequent plugging and unplugging of the display and peripheral interfaces in the prior art, and achieves the effect of flexibly switching the target controller to be debugged, thereby improving debugging efficiency.

[0037] The utility model also provides a switching system for controller debugging. The switching device for controller debugging can reduce the number of plug-in and unplugging times of the display screen and the peripheral interface, and can flexibly switch the connection relationship between the display screen and different peripherals and multiple controllers to be debugged, thereby improving the debugging efficiency. Since the principle of solving the problem by the switching system in the embodiment of the present application is similar to the switching device in the embodiment of the present application, the implementation of the switching system can refer to the implementation of the switching device, and the repeated parts will not be repeated.
