Embodiment Construction

[0006] A wireless mouse based on Zigbee. The main control chip of the mouse sending end is JNS121, which is connected to the clock line and data line of the mouse by GEN20, and the GEN38 is connected to the ground of the mouse; the receiving end is composed of two hardware modules: zigBee module and usB module; zigBee The module is responsible for receiving the mouse displacement and key data packets transmitted from the sending end, and the USB module is responsible for sending the data packets to the computer host.

[0007] The sending end of the mouse is composed of two modules, namely ZigBee module and PS / 2 module. The ZigBee module needs to find the zigBee network and try to connect to the receiving end, handle the collection and sending of mouse data, and the PS / 2 module mainly handles the initialization of the PS / 2 mouse.

[0008] PS / 2 module, the most important task is to initialize the mouse, the PS / 2 mouse actively sends data information such as keys and displacement...

Abstract

The invention relates to a Zigbee-based wireless mouse. A main control chip of a transmitting end of the mouse is JNS121 and connected to a clock line and a data line through GEN20, and GEN38 is connected with a ground wire of the mouse. A receiving end consists of two hardware modules including a zigBee module and a USB module, the zigBee module is responsible for receiving mouse displacement and key data packets transmitted from the transmitting end, and the USB module is responsible for sending the data packets to a computer mainframe. The Zigbee technology mainly has advantages of low power consumption, to be more specific, two normal AA batteries can be used for 6 months to 2 years; low cost, to be more specific, cost is greatly reduced due to low zigBee data transmission rate and simple protocols, and zigBee protocols are free of patent charge; high network capacity, to be more specific, each zigBee network is capable of supporting 255 devices at most; short time delay, to be more specific, time delay is in a range of 25-30 milliseconds generally.

Description

technical field [0001] The invention relates to a wireless mouse based on Zigbee. Background technique [0002] Bluetooth is a standard established by a private non-profit organization 510 (speeial Interest Group) established in September 1998. The frequency band used by Bluetooth is consistent with 2.4GRF, which is free and unlicensed in most countries. Between 2.4 and 2.485GHzIsM , but Bluetooth technology adds adaptive frequency modulation technology to ordinary 2.4G wireless technology, which can realize full-duplex transmission mode and automatic frequency modulation of 1600 times per second. In addition, the transmission rate of Bluetooth technology is up to IMBPs per second, which is higher than 27MHz wireless technology "According to the long distance of use, Bluetooth can be divided into industrial use / Classl0 standard, daily use / Class2., standard and the shortest transmission distance / Class30 standard." Among them, the standard power consumption of CfassZ for wirel...
