Problems solved by technology

In this way, a lot of work needs to be done from scratch, and it is easy to repeat mistakes
The developer needs to change the code branch, generate a new driver, and solve the error problem again, using a new debug file, wasting a lot of unnecessary time and energy

Embodiment Construction

[0026] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the described examples.

[0027] For different sensor configuration schemes in the prior art, multiple sets of combo drivers and multiple sets of driver codes are required, and the algorithm libraries used are all fusion algorithm libraries (fusion algorithm library is a kind of raw data collected from physical sensors to obtain Algorithm library for virtual sensor results), but the working mode used when the fusion algorithm library is called is different, and the different working modes lead to different virtual sensors reported by the driver to the upper layer. In the multi-branch driving code, the working mode is determined by the software application engineer by rewriting the macro definition in the code according to the actual connected physical sensor. From a software point of view, the difference between the driver codes of different conf...

Abstract

The invention discloses a sensor driving method and a driving system suitable for Windows operating system. The sensor driving method includes: detecting the working mode of a sensor connected to an application processor; The mode calls the algorithm library to calculate the virtual sensor result; reports the virtual sensor result to the application processor. For users, after changing the sensor configuration scheme, they only need to change the I2C slave address in the ACPI table at most, and it is no longer necessary to update the entire drive system, which reduces a lot of workload, and especially greatly simplifies the difficulty for users to transplant drivers. and time. For developers, code branches are reduced, only one set of driver code needs to be maintained, and when debugging problems occur, they only need to use the same debugging file to capture information for analysis, which also reduces the workload.

Description

technical field [0001] The invention relates to the field of sensor driving, in particular to a sensor driving method and driving system suitable for Windows operating system. Background technique [0002] With the promotion of Windows system on mobile devices in recent years, more and more tablets and mobile phones choose Windows system as their operating system, and the number of sensors applied to mobile devices is also increasing. Different from the hardware design of single-use accelerometers on laptops, the sensor solutions on mobile devices are more diverse, and more are equipped with six-axis or nine-axis sensor solutions. In order to obtain better user experience and calculation accuracy, the fusion algorithm is used and applied to the six-axis and nine-axis configuration schemes for the sensor. [0003] In order to save costs, some existing sensor configuration solutions are designed in the way of I2C directly connecting the sensor, and there is no MCU (Micro Cont...
