Abstract
The invention relates to a method for communication between a terminal and a computer. The method comprises following steps: S1, utilizing a human interface device interface of a universal serial bus to receive first data sent by the computer through a universal serial bus interface; S2, sending received first data to a control chip through a universal asynchronous transceiver joint such that the first data received can be conveniently processed by the control chip, wherein the control chip has a controller conversion module with a first working mode and a second working mode; the first working mode is connection between a first port and a first control port of a first group of USB control ports; and the second working mode is connection between the first port and a first control port of a second group of USB control ports; and controlling the controller conversion module to shift from the first working mode to the second working mode after recognizing that USB equipment connected with the first port is allowed to use.
Description
Technical field
A kind of method that the present invention relates to terminal and compunication.
Background technology
Usb protocol is flexible, can support to synchronize and simultaneous asynchronous data transmissions, and provides one can extensively receive respectively
The standard interface of the equipment of kind, therefore, is widely used in connection computer and mobile phone.At present, nearly all
Mobile phone is all supported to use USB line and intercomputer to carry out data interaction, and this mutual process is: led to by mobile phone
Cross USB line and computer to connect, when COMPUTER DETECTION is to after having USB device insertion, it is judged that this USB sets
Whether standby driver is installed, and without installation, then computer refusal communicates with mobile phone, and bullet
Go out to install the prompting frame that USB drives；Only after being mounted with that USB drives, mobile phone could be with USB device
Identity communicate with computer.State mobile phone in realization by during USB and compunication,
Inventor finds that in prior art, at least there are the following problems: after mobile phone and computer first connection, it is necessary to
First installing USB and drive mobile phone ability and compunication, otherwise communication cannot be carried out.But hands sometimes
The USB device driver of machine carries the most at random, or can not be driven journey at some special occasions computer
The installation of sequence, like this must first install USB and drive and just can carry out the mode of mobile phone and compunication
Can be restricted.
Summary of the invention
For solving above-mentioned technical problem, a kind of method that it is an object of the invention to provide terminal and compunication,
Still computer can be made in the case of computer is fitted without terminal USB (universal serial bus) driver
With being in communication with each other of terminal.
The terminal of the present invention and the method for compunication, comprise the following steps:
S1: use USB (universal serial bus) human interface devices interface computer to pass through USB
The first data sent；
S2: the first data received are sent to control chip by UART Universal Asynchronous Receiver Transmitter interface, in order to
The first data received are processed by described control chip；
S3: the second data sent by control chip are forwarded to USB (universal serial bus) through UART Universal Asynchronous Receiver Transmitter interface
Human interface devices interface；
S4: by described second data by described USB (universal serial bus) human interface devices interface, and by general
Serial bus interface sends to computer, in order to described second data are processed by described computer.
Described control chip has the controller modular converter of the first mode of operation and the second mode of operation；Described
First mode of operation is that the first control port in the first port and first group of USB control port connects, described
Second mode of operation is that the first control port in the first port and second group of USB control port connects；Work as knowledge
After not going out the USB device that the USB device being connected with described first port is permission use, control described control
Device modular converter processed is switched to the second mode of operation by the first mode of operation.
The present invention at least has the advantage that the present invention uses USB (universal serial bus) human interface devices interface to connect
Receive the first data that computer is sent by USB (universal serial bus)；The first data received are passed through general different
Step transceiver interface sends to control chip, in order to the first data received are carried out by described control chip
Process, owing to computer system of the prior art acquiescence is with the driver of HID interface, therefore, nothing
Opinion computer whether already installed with the driver of terminal, then can identification terminal, and lead to terminal
Letter.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technology of the present invention
Means, and can be practiced according to the content of description, describe in detail with presently preferred embodiments of the present invention below
As rear.
Accompanying drawing explanation

Lower embodiment is used for illustrating the present invention, but is not limited to the scope of the present invention.
See Fig. 1, Fig. 2, a kind of terminal described in a preferred embodiment of the present invention and the method for compunication,
Comprise the following steps:
S1: use USB (universal serial bus) human interface devices interface computer to pass through USB
The first data sent；
S2: the first data received are sent to control chip by UART Universal Asynchronous Receiver Transmitter interface, in order to
The first data received are processed by described control chip；
S3: the second data sent by control chip are forwarded to USB (universal serial bus) through UART Universal Asynchronous Receiver Transmitter interface
Human interface devices interface；
S4: by described second data by described USB (universal serial bus) human interface devices interface, and by general
Serial bus interface sends to computer, in order to described second data are processed by described computer.
Described control chip has the controller modular converter of the first mode of operation and the second mode of operation；Described
First mode of operation is that the first control port in the first port and first group of USB control port connects, described
Second mode of operation is that the first control port in the first port and second group of USB control port connects；Work as knowledge
After not going out the USB device that the USB device being connected with described first port is permission use, control described control
Device modular converter processed is switched to the second mode of operation by the first mode of operation.
The present invention at least has the advantage that the present invention uses USB (universal serial bus) human interface devices interface to connect
Receive the first data that computer is sent by USB (universal serial bus)；The first data received are passed through general different
Step transceiver interface sends to control chip, in order to the first data received are carried out by described control chip
Process, owing to computer system of the prior art acquiescence is with the driver of HID interface, therefore, nothing
Opinion computer whether already installed with the driver of terminal, then can identification terminal, and lead to terminal
