Problems solved by technology

[0004] In the process of realizing the present invention, the method of the prior art also needs the support of additional hardware, and when the status information of the sensor has not changed, the electronic terminal still needs to re-acquire the status information of the sensor, so the prior art will Cause waste of resources and low call efficiency

Embodiment Construction

[0024] An embodiment of the present invention provides a method for invoking a sensor. The method is applied to an electronic terminal. The method can save hardware resources and improve the efficiency of invoking the sensor.

[0025] In order to enable those skilled in the art to understand the present invention in more detail, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] like figure 1 as shown, figure 1 It is a flow chart of calling a sensor method in an embodiment of the present invention, the method of this embodiment includes:

[0027] Step 110: the program module detects whether the sensor needs to be invoked;

[0028] Step 112: When the sensor needs to be called, the program module sends a command to call the sensor;

[0029] Step 114: the basic input and output module receives the instruction;

[0030] Step 116: The basic input and output module obtains the sensor state information in the storage un...

Abstract

The invention discloses a method for calling a sensor. The method comprises the following steps: whether a program module needs to call a sensor or not is detected, when the program module needs to call the sensor, the program module sends an instruction to call the sensor, a basic input-output module receives the instruction, and acquires the sensor state information in a storage unit based on the instruction, wherein the sensor state information is mapped to the storage unit from a controller, and the basic input-output module sends the sensor state information to the program module. Through the invention, hardware resources can be saved, and the sensor calling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for invoking a sensor. Background technique [0002] With the advent of the new technological revolution, the world has entered the information age. In the process of using information, it is first necessary to obtain accurate and reliable information. The sensor can feel the measured information, and can transform the information sensed by the detection into electrical signals or other required forms of information output according to certain rules. To meet the requirements of transmission, processing, storage, display, recording and control of information, sensors are the main way and means to obtain information. In the application of the sensor, it is necessary to obtain the sensor status information, that is, to call the sensor. [0003] In the prior art, a south bridge or an MCU (Micro Control Unit, micro control unit) is usually used to call a sensor to achieve...
