The switching of the two working modes and the switching of the functions can be completed by the main control module according to the received signals from the keyboard shortcut keys.

The specific operations in the setting mode and the operation mode are explained in detail below, respectively.

In a setting mode, the working principle of the mouse and keyboard converter is as follows:

the setting of the mapping relationship between the buttons and the keys on the joystick and the keyboard and between the buttons and the rocker on the joystick and the cursor movement and keys on the mouse can be set by two conventional methods: (1) setting the mapping relation by adopting conventional mapping setting software installed on a computer (or electronic mobile equipment such as a mobile phone/a tablet computer and the like), and storing the mapping relation in a memory module through a main control module; (2) the main control module adopts a singlechip with a mapping processing function, each button and rocker of the gamepad are mapped to the corresponding keys of the mouse/keyboard through the mapping function of the main control module, and the main control module stores the corresponding mapping relation in the memory module. The following explains the principles of the two mapping relationship setting methods.

1. Setting mapping relation through mapping setting software

As an implementation manner of the mapping relationship setting, as shown in fig. 10, the USB Device module (or the wireless communication module) is connected to a computer (e.g., a computer (PC), a mobile phone or a tablet (IPAD)) installed with mapping setting software (e.g., reWASD handle mapping keyboard software), the mapping relationships between buttons and rockers on the joystick and keys on the keyboard, and between buttons and rockers on the joystick and cursor movements and keys on the mouse can be set by using conventional mapping setting software (e.g., reWASD handle mapping keyboard software) installed on the computer (conventional operation, which is not described again), and the mapping relationships are stored in the memory module through the USB Device module (or the wireless communication module) via the main control module.

2. Setting mapping relation through single chip microcomputer

In this embodiment, the chip U3 is in communication connection with the chip U2, and the chip U2 is connected to the game pad, the keyboard, and the mouse through the USB1 interface, the USB0 interface, and the USB2 interface. The U2 processes the signals received from the game pad, keyboard and mouse, converts them into parallel data, and forwards them to the chip U3. In the set mode, the chip U3 associates the received signal from the joystick with the signal from the keyboard or mouse, thereby establishing a mapping relationship between the joystick and the keyboard or mouse, and saves the association information of the joystick and the keyboard or mouse (i.e., the mapping relationship between the joystick and the keyboard or mouse) to the chip U6.

Based on the main control module structure, the mapping relations between the buttons on the gamepad and the keys on the rocker and the keyboard, and between the buttons on the gamepad and the rocker and the cursor movement and keys on the mouse are set, and the main setting can be divided into keyboard or mouse key setting and mouse sliding setting.

The keyboard or mouse key setting method includes the following steps:

s1, pressing KEY _ F12 and KEY _ F11 to enter setting mode;

s2, pressing the button of the game handle (the cross key can support 8 direction settings);

s3, pressing a key on the keyboard or mouse to be set (the key only supports the function corresponding to the single key), sending the button signal of the game handle and the signal of the corresponding key on the keyboard or mouse to the main control module through the USB Host module, associating the received handle button signal with the signal of the corresponding key on the keyboard or mouse together by the main control module, establishing the mapping relation between the game handle and the keyboard key signal or mouse key, and storing the established mapping relation to the memory module.

S4, releasing the button on the handle;

and repeating the steps S2-S4 until all the buttons of the gamepad are mapped.

S5, while KEY _ F12 and KEY _ F11 are pressed, enter the operation mode.

Each page area can set different mapping relations for keyboard or mouse keys. The keyboard or mouse button setting of each page area can be set independently. In the setting mode, firstly, the corresponding page area is switched through a function switching shortcut key, and then the steps S2-S4 are repeated to complete the keyboard or mouse key setting of the current page area; and switching to another page area through the function switching shortcut key, and continuously repeating the steps S2-S4 until the keyboard or mouse keys in all the page areas are set.

The mouse sliding setting method comprises the following steps:

s1, pressing KEY _ F12 and KEY _ F11 to enter setting mode;

s2, pushing the joystick to the bottom (in any direction of up, down, left and right) in the left 3D (namely, left rocker) or right 3D (namely, right rocker) direction;

s3, sliding the mouse (the mouse only supports the left 3D or right 3D corresponding function), sending the rocker signal of the gamepad and the mouse corresponding action signal to the main control module through the USB Host module, associating the received rocker left 3D or right 3D signal and the mouse corresponding action signal together by the main control module, establishing the mapping relation between the gamepad and the mouse sliding operation, and storing the established mapping relation to the memory module.

S4, releasing a rocker on the game handle;

and repeating the steps S2-S4 until all the rocker mapping of the gamepad is completed.

S5, while KEY _ F12 and KEY _ F11 are pressed, enter the operation mode.

Each page area can set different mapping relations for mouse sliding. The mouse slide setting of each page area can be set independently. In the setting mode, firstly, the mouse is switched to a corresponding page area through a function switching shortcut key, and then the steps S2-S4 are repeated to complete the mouse sliding setting of the current page area; and switching to another page area through the function switching shortcut key, and continuously repeating the steps S2-S4 until the mouse sliding setting of all the page areas is finished.

If the game handle button is not pressed or the rocker is not pushed in the setting process, the originally set key functions on the keyboard or the mouse can be cleared. After entering the setting mode, the game device leaves the setting mode after the mapping setting is finished (namely, each button and rocker of the game handle are mapped to the corresponding button of the mouse/keyboard).

According to the setting operation, different game pads are used for guidance, and specific mapping relation settings are shown in tables 2 and 3.

In the second operation mode, the operation principle of the mouse-keyboard converter is as shown in fig. 11, which is specifically as follows:

(1) mouse/keyboard/handle operation signal

The USB Host module reads signals of a mouse or/and a keyboard and transmits the signals of the mouse or/and the keyboard to the main control module, and the main control module reads the set mapping relation out of the memory module according to the received signals of the mouse or/and the keyboard; the main control module takes the mouse or/and keyboard signals as corresponding handle signals according to the mapping relation, and then transmits the handle signals to the game host in a wireless or limited mode through the USB Device module (or the wireless communication module); when the main control module receives the keyboard and mouse signals at the same time, the main control module reads the mapping relation corresponding to the keyboard and mouse signals from the memory module, integrates the keyboard and mouse signals as corresponding handle signals according to the mapping relation, and transmits the handle signals to the game host in a wireless or limited mode through the USB Device module (or the wireless communication module). The integration is to combine the operation signals of the handles together, for example, the game handle corresponding to the keyboard signal is operated as "under cross key", the game handle corresponding to the mouse signal is operated as "left handle right rocker", and at this time, the main control module can integrate the keyboard signal as "under cross key" and the mouse signal as "left handle right rocker", and the obtained integrated handle signal is "under cross key" and "left handle right rocker". In order to maintain the consistency of the transmission speed of the grip signal, the greater transmission speed (i.e. the rate of return) of the keyboard and the mouse can be used as the transmission speed of the integrated grip signal, and the integrated grip signal can be sent to the USB Device module or the wireless communication module.

The mouse signal refers to a left mouse button, a right mouse button, a middle mouse button triggering signal or a mouse position movement induction signal and the like; the keyboard signal is a corresponding key triggering signal; the game handle signal is a trigger signal of a corresponding key of the handle or a direction signal of a rocker and the like.

(2) Audio signal

The USB Device module (or the wireless communication module) acquires an audio signal of the game host, the audio signal is transmitted to the audio module through the main control module, and an earphone connected with the audio module outputs audio; if the game handle is connected with the earphone, the audio data is also transmitted to the game handle through the USB Host module, and the earphone connected with the game handle also outputs the audio.

The audio module can also read the voice signal (i.e. audio signal) input by the microphone connected with the audio module, and after converting the voice signal into a digital signal, the digital signal is transmitted to the game host by the USB Device module (or the wireless communication module). Or, if the game handle is connected with a microphone, the USB Host module reads the voice signal input by the microphone connected with the game handle, transmits the voice signal to the main control module, and transmits the voice signal to the game Host through the USB Device module (or the wireless communication module).

(3) Handle vibration signal

When the handle can be operated, the USB Device module (or the wireless communication module) acquires a handle vibration signal of the game Host and transmits the handle vibration signal to the main control module, and then the USB Host module transmits handle vibration data to the game handle to enable the game handle to execute corresponding vibration.
