Abstract

The invention provides a device which can realize USB hid mouse function on a touch device. The device is characterized in that: the device comprises touch detection MCU, a master chip and a USB interface module which are connected in sequence; HID equipment descriptors are arranged in the master chip. The device realizes that a user of the equipment can directly use the equipment without installing a drive program and without considering the compatibility of the drive programs of different products by adopting the USB module and built-in HID equipment descriptors; meanwhile, the device is characterized by high speed, instant use after inserting and hot plugging-supporting, thus ensuring that the connection of peripheral devices with a computer is more efficient and convenient; the device can be directly used on various positioning devices for realizing the mouse function, ensuring more convenient and flexible use and stronger compatibility.

Description

technical field [0001] The invention relates to an input technology on a touch device, in particular to a device and a method for realizing the USBHID MOUSE function on the touch device. Background technique [0002] The USB interface has the following advantages: plug and play (Plug and Play) features, and has the function of automatic detection; it can be expanded to 127 devices, supports hot plugging, and does not need to turn off the system power; the transmission rate can reach up to 480Mbps (USB2 The .0 protocol supports 480Mbps, and the USB1.1 protocol supports a maximum of 12Mbps), which can meet the transmission and use needs of most devices. [0003] Human Interface Device (HID, Human Interface Device) is a device that does not need to be developed by the user and can be used by plugging into the Windows operating system. All HID devices are driven by the HID device class driver (hidclass.sys) that comes with the system. ) to establish contact with the application...
