Embodiment

Below in conjunction with specific embodiment, the utility model is more specifically described in detail.

Embodiment

As shown in Figure 1.The utility model is wireless WIFI mouse, comprises microprocessor module, WIFI module, mouse module, power module;

Described power module is electrically connected with microprocessor module, WIFI module and mouse module simultaneously;

Microprocessor module is electrically connected with mouse module with WIFI module more respectively.Being specially microprocessor module take controlled processing unit as core, information interchange is carried out by serial communication and WIFI module, mouse module needs to interrupt by producing request signal triggers microprocessor during transmission data, when meeting interrupt response condition, microprocessor module carries out interrupt response, is obtained the data of mouse module by data line.When terminal device runs wireless WIFI mouse driver, set up AP focus, if now start mouse power supply, then microprocessor module begins through serial communication and WIFI module is initialized as serial ports turns STA mode, and TCP service end pattern and initialization should connect network name, the parameter such as cipher mode and key of focus.Microprocessor module controls WIFI module and sends connection request signal to the AP focus of specifying, WIFI mouse driver authentication password that terminal device is wireless correctly passes through IP address assignment algorithm assigns IP address afterwards to WIFI module, thus WIFI module can connect AP focus, then sent the answer signal successfully connecting focus to microprocessor module by serial communication.Then microprocessor enters the state of moment monitoring mouse module data variation.Mouse module clock line is electrically connected with microprocessor module interrupt request line, and data line is electrically connected with its data I/O port.Data line and clock line are all high level under normal circumstances, and when mouse has data to send, it first detects clock line, confirm that clock line is high level.If not, be then that microprocessor inhibits communication, mouse must cushion any data that will send, until regain the control of bus.If clock line is high level, mouse just can start to transmit data.When clock line transfers low level to from high level, clock line negative edge triggers microprocessor external interrupt, now microprocessor just starts the data of reading mouse, then data is processed, send to WIFI module via serial communication, then be sent to terminal device by WIFI module.After the driver of terminal device receives data, resolved by algorithm, then this is responded.

WIFI module is used for terminal device is communicated with mouse.

Described WIFI module is single antenna module.Support wireless standard: IEEE 802.11n, wireless transmission rate reaches as high as 150Mbps, IEEE 802.11g and reaches as high as 54Mbps, IEEE 802.11b and reach as high as 11Mbps, support 64/128 WEP encryption, adopt WPA-PSK/WPA2-PSK, WPA/WPA2 security mechanism.WIFI module adopts LVTTL serial interface communication mode and microprocessor to carry out bidirectional transfer of information, and serial ports allocating default form is: baud rate is 115200Bd, and data bit is 8, does not have check bit, and position of rest is 1.Microprocessor configuration WIFI module parameter, is specially:

Mode of operation is selected: wireless network card pattern

Procotol is selected: TCP server

IP address class type: dynamically

Wireless parameter: AP hot spot networks title (SSID), cipher mode and password that module will be connected to.

Port: the listening port that TCP server is opened

Enable DHCP: after enabling DHCP, WIFI module obtains IP address by above configuration from AP focus automatically, and WIFI module 2 makes terminal device can carry out proper communication with mouse.The data that mouse module will send, by after the process of microprocessor module, are sent to the transmission buffer zone of WIFI module, then deliver to terminal device via the channel set up between WIFI module and terminal device.

Power module adopts DC chopper circuit, and 9v voltage transitions is become 5v or 1.5v.Supply microprocessor module, WIFI module and mouse module respectively.Described mouse module can adopt optical mouse module (PS/2, USB) or mechanical mouse module (PS/2, USB), and mouse module only need provide clock line and data line two lines to be electrically connected with microprocessor module.
