Embodiment 1

[0038] Such as figure 1 As shown, the information transmission method provided by the embodiment of the present invention includes the following steps:

[0039] S101. When the mobile terminal receives a trigger instruction, it sends an activation instruction to the external device through the earphone interface, so that the external device transmits information to the mobile terminal.

[0040] Specifically, the user inputs a trigger command by clicking or touching, the mobile terminal receives the trigger command, the processing control unit generates a start command, and sends the start command to the serial data line of the I2C bus through the sound channel of the earphone interface. , and transmit the start command to the external device through the serial data line. The sound channel includes a left channel and a right channel, and the left channel or the right channel can be used as the channel for starting the command, or both the left channel and the right channel can ...

Embodiment 2

[0047] Such as figure 2 As shown, the second embodiment is optimized on the basis of the first embodiment: after step S102, step S103 is added: send the information to the processing control unit of the mobile terminal, and the processing control unit displays or saves it in real time.

[0048] Specifically, after the mobile terminal receives the information through the microphone interface, the analyzed information is sent to the processing control unit in the mobile terminal through analog-to-digital conversion or decoding, and the processing control unit displays or saves the information in real time, and the user can view the information in real time Or use a mobile terminal for backup and storage.

Embodiment 3

[0050] Such as image 3 As shown, an information transmission device provided by an embodiment of the present invention includes the following modules:

[0051] The command sending module 10 is configured to send a startup command to the external device through the earphone interface when the mobile terminal receives the trigger command, so that the external device transmits information to the mobile terminal.

[0052] Specifically, the sound channel interface of the mobile terminal is connected to the I2C bus, and the startup command is sent to the serial data line of the I2C bus, and then transmitted to the external device through the serial data line. The sound channel includes a left channel and a right channel, and the left channel or the right channel can be used as the channel for starting the command, or both the left channel and the right channel can be used as the channel for starting the command.

[0053] The information receiving module 20 is used for the mobile t...

Abstract

The invention discloses an information transmission method and device and a mobile terminal and belongs to the technical field of the mobile terminal. The information transmission method includes that when the mobile terminal receives a triggering command, sending a starting command to an external device through an earphone interface, and enabling the external device to transmit information to the mobile terminal; receiving the information transmitted from the external device through the earphone interface. According to the information transmission method, the starting command is sent to the external device through the earphone interface of the mobile terminal, the information transmitted from the external device is received through the earphone interface, and then a new way is provided for transmitting information between the mobile terminal and the external device; when a USB interface is taken up, or the requirement on the information transmission speed rate is low, the earphone interface is used for transmitting the information, the resource occupation rate is low, and the resource is saved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an information transmission method, device and mobile terminal. Background technique [0002] The current smart terminals (smartphones, tablets, etc.) are usually connected to peripherals through wireless connections (NFC, WIFI, Bluetooth, etc.) and USB interface connections. For some peripherals that do not have wireless connections (such as Existing pressure sensors, financial terminal equipment, etc.) can only be connected to the smart terminal through the USB interface. When the USB port is occupied, these peripherals cannot be connected to the smart terminal. It is inconvenient to use. In addition, the USB port communication method needs to go through a certain protocol stack. Although its information transmission rate is high, the resource occupancy rate is also relatively large. For some peripherals that do not require a high transmission rate, they can o...
