Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: referring to fig. 1, a high performance keyboard mouse synchronous controller, includes master control MCU, master control MCU is connected with keyboard mouse interface IC and SPI data bus, SPI data bus is connected with a plurality of USB ICs, USB IC is connected with the USB interface, and the USB interface is used for being connected to mouse interface, keyboard interface or handle interface on computer or other equipment through the data line. The keyboard and mouse interface IC is connected with a keyboard interface, a mouse interface and a handle interface which are respectively used for connecting a keyboard, a mouse and a handle for operation. The main control MCU is used for sending out instructions and analyzing and processing data; the SPI data bus is used for transmitting data; and the keyboard and mouse interface IC is used for reading data of a keyboard, a mouse and a handle and transmitting the data to the main control MCU. The IC is an integrated circuit. The master MCU can use Stm32f108C8T6, the keyboard and mouse interface IC can use CH374u or CH559, and the USB IC can use CH551 or CH 552G.
The master control MCU is also connected with a serial interface which can be connected to the serial interface of another (called next stage) keyboard and mouse synchronous controller through a data line so as to communicate between the master control MCU and the other. The serial interfaces can be arranged in multiple numbers, each serial interface can be connected to the serial interface of another keyboard and mouse synchronous controller through a data line so as to transmit the data of the keyboard, the mouse or the handle to the other keyboard and mouse synchronous controller, and the other keyboard and mouse synchronous controller transmits the data to the computer and other devices connected with the other keyboard and mouse synchronous controller. Similarly, the next-stage keyboard and mouse synchronous controller can also communicate with another (next-stage) keyboard and mouse synchronous controller through a serial interface.
The USB IC is also connected with an LED indicator light for indicating whether the USB IC is in a working state.
The working principle is as follows: as shown in fig. 1, the main control MCU reads data of the keyboard, the mouse, or the handle in real time through the keyboard-mouse interface IC, and then analyzes and processes the data, and outputs the data in the following two ways after analyzing and processing the data as required: in the first mode, the main control MCU sends data to the USB interface through the SPI data bus and the USB IC, and real-time (synchronous) or time-sharing (asynchronous) control is carried out on equipment such as a computer connected with the USB interface; and in the second mode, the data is sent to the next-stage keyboard and mouse synchronous controller in a serial port data mode (the next-stage keyboard and mouse synchronous controller is connected with a plurality of computers), so that the simultaneous control of all the devices is realized.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the utility model and are not to be construed as limiting the utility model.
