The embodiment of the application also discloses a multi-mode switching control method for the mouse, which is applied to a control chip of a multi-mode switching control circuit, as shown in fig. 1, and comprises steps S110-S130.
S110, acquiring the input connection signal.
The control chip can receive the input connection signals, and after other components are inserted into the corresponding ports and are electrically connected, the control chip can receive the input connection signals. The component can be directly and electrically connected with the pin of the control chip, and can be indirectly and electrically connected with the pin of the control chip through the adapter or other circuits, whether the component is directly and electrically connected with the pin of the control chip or indirectly connected with the pin of the control chip, and after the component is electrically connected, the control chip can certainly receive the input connection signal.
S120, determining a corresponding working mode from a preset configuration table according to the connection signal.
And then, determining the working mode corresponding to the connection signal from a preset configuration table in the control chip according to the received connection signal, wherein the signal type contained in the connection signal and the number of various types of signals are required to be matched with different working modes, and the configuration table contains a plurality of working modes, the signal type corresponding to each working mode and the number of various types of signals.
In a specific embodiment, step S120 specifically includes the sub-steps of: classifying the connection signals to determine the number of signals corresponding to each classification; the classification comprises a key connection signal, a roller connection signal, a light connection signal and a sensor connection signal; and acquiring working modes matched with the number of signals corresponding to each category from the configuration table.
Specifically, the connection signals may be classified, so as to determine the number of signals corresponding to each classification, where the signal classification may include a key connection signal, a roller connection signal, a light connection signal, and a sensor connection signal, where the key connection signal corresponds to a key configured in the mouse, the roller connection signal corresponds to a roller configured in the mouse, the light connection signal corresponds to a display lamp configured in the mouse, and the sensor signal corresponds to a sensor configured in the mouse. After the connection signals are classified, the number of signal paths corresponding to each signal classification can be determined, namely the number of signals corresponding to each signal classification is determined.
In a more specific embodiment, each signal classification may be further subdivided according to specific type information such as connection protocol type, connection pin number, etc. of the connection signal. If the number of signals respectively corresponding to the connection protocol types in the same signal classification is determined, the number of signals respectively corresponding to the connection pins in the same signal classification is determined.
In a specific embodiment, the classifying the connection signals to determine the number of signals corresponding to each classification specifically includes: preliminary classification is carried out on the connection signals so as to determine the number of signals corresponding to each classification; the signals corresponding to each category are subdivided to determine the number of signals corresponding to the sub-categories included in each category.
In the practical application process, firstly, the connection signals are initially classified, so that the number of signals corresponding to each classification is determined, and the specific implementation process is shown in the steps. Then, each signal classification can be further subdivided, so that the number of signals corresponding to the sub-classifications contained in each classification is determined, for example, key connection signals are further subdivided into main key connection signals, side key connection signals and the like, and roller connection signals are further subdivided into main roller connection signals, side roller connection signals and the like; the lamplight connection signal is further subdivided into a monochromatic lamplight connection signal, a color lamplight connection signal and the like; the sensor signals are further subdivided into mouse cursor sensor signals, life sensor signals (e.g., heartbeat sensor signals, blood pressure sensor signals), operation sensors (e.g., level detection sensors), and the like.
According to the number of signals corresponding to each signal class, a matched working mode can be obtained from the configuration table in a matching way.
In a specific embodiment, step S120 specifically further includes the sub-steps of: judging whether the connection signal contains a power supply connection signal and a data transmission connection signal or not to obtain a judging result; and determining a corresponding power supply mode and a data receiving and transmitting mode according to the judging result.
In the process of determining the corresponding working mode, whether the connection signal contains the power supply connection signal and the data transmission connection signal or not can be judged, and corresponding judging results are obtained, and whether the connection signal contains the power supply connection signal and whether the connection signal contains the data transmission connection signal or not is two independent judging processes. For example, if the power supply port of the mouse is plugged into the USB interface of the external device (such as a computer), the external device (such as a computer) can supply power to the mouse through the USB interface, so that the connection signal detected by the control chip includes a power supply connection signal; if the data transmission port of the mouse is plugged into the USB interface of the external device (such as a computer), the external device (such as the computer) can transmit data between the USB interface and the mouse, so that a control signal generated by a user operating the mouse is sent to the external device (such as the computer).
The corresponding power supply mode and data receiving and transmitting mode can be determined according to the judging result, specifically, if the connecting signal is judged to contain the power supply connecting signal, the mouse can be powered through the external equipment, and the power supply mode is determined to be the external power supply mode; if the connection signal does not contain the power supply connection signal, the mouse can be powered by a battery (a rechargeable battery or a non-rechargeable battery) arranged in the mouse, and the power supply mode is determined to be an internal power supply mode. If the connection signal is judged to contain the data transmission connection signal, data transmission can be carried out between the connection line and the external equipment, and the data receiving and transmitting mode is determined to be a wired receiving and transmitting mode; if the connection signal is determined to not include the data transmission connection signal, data transmission can be performed between the antenna (E1 shown in fig. 6) disposed in the mouse and the external device, and the data transmission/reception mode is determined to be the wireless transmission/reception mode.
S130, processing the connection signal according to the working mode and outputting a control signal corresponding to the connection signal.
After the working mode is determined, the control chip can execute signal processing logic corresponding to the working mode to process the connection signal and output the control signal obtained after the processing. The control signal may include only an operation control signal for controlling the external device, and the control signal may also include an operation control signal for controlling the external device and a feedback control signal for controlling a component disposed in the mouse.
In a specific embodiment, step S130 specifically includes the sub-steps of: processing the connection signal according to a control signal processing rule in the working mode to obtain a corresponding operation control signal; the operation control signal is output to an external device connected with the mouse so as to control the external device; processing the connection signal according to a feedback control rule in the working mode to obtain a corresponding feedback control signal; and the feedback control signal is output to components configured in the mouse so as to control the components.
The working mode comprises a control signal processing rule, the connection signals can be processed according to the control signal processing rule, and specifically, multipath signals used for controlling external equipment in the connection signals can be integrated according to the control signal processing rule. For example, the main key connection signal and the mouse cursor sensor signal need to be integrated correspondingly, so as to determine a specific position and a specific action for operating the external device, and then the main key connection signal and the mouse cursor sensor signal can be integrated according to a control signal processing rule in a corresponding working mode, so that a corresponding operation control signal is obtained, and the operation control signal can be sent to the external device to control the external device.
The connection signal can also be processed according to the feedback control rule in the working mode to obtain a corresponding feedback control signal. For example, when the display lamp is assembled with the mouse, the display lamp can be controlled to flash according to the connection information of the main key, and the feedback control rule includes: the display lamp flashes once when the user clicks the left button of the mouse, and the display lamp flashes twice when the user clicks the right button of the mouse, so that the command for controlling the display lamp to flash is a feedback control signal; the control display lamp correspondingly adjusts the brightness according to the side roller connection signals, and then the instruction for controlling the display lamp to adjust the brightness is also another feedback control signal, and the feedback control signal can be sent to components configured in the mouse so as to control the internal components.
