Problems solved by technology

[0002] In the actual development of student education tablets, smart tablets, and smart phones, we often encounter the need to update the touch screen parameter effects of the already shipped machines, especially large-sized machines , the current method of updating touch screen parameters on the market needs to modify the kernel or system partition, resulting in the need to recompile the new ROM package for each update. To compile the ROM package, it needs to be fully compiled, involving many developers and wasting a lot of time. Updating the ROM test department needs to test the entire ROM package, and it will waste a lot of time to turn off and burn many test machines

Embodiment Construction

[0014] The present invention will be further described below. It should be noted that this embodiment takes the technical solution as the premise, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0015] This embodiment provides an Android-based method for updating touch screen parameters through an app, and the specific process is:

[0016] The kernel driver creates a sys device node through sysfs_create_file, and implements the store function prototype. The store function obtains the parameter content in the buf, and saves it after parsing and verification; by calling the fw_update function corresponding to the TP driver, the above parameter content is written to the touch screen. On the hardware; add the corresponding authority in Selinux, so that the device node can write normally through the specified upper-layer APP;

[0017] When updating touch screen par...

Abstract

The invention discloses a method for updating parameters of a touch screen through an app based on Android, the parameters of the touch screen are upgraded by updating the app, the system compiling time of developers and the testing time of testers are shortened, and the version number of system upgrading is reduced. The user can update the touch screen effect without updating the system OTA, the use is more convenient, and more time is saved for the user. In addition, the stability of the system can be improved, and the problem that the system goes wrong due to the fact that the effect of one touch screen is modified or compilation goes wrong is avoided.

Description

technical field [0001] The invention relates to the technical field of the android system, in particular to an android-based method for updating touch screen parameters through an app. Background technique [0002] In the actual development of student education tablets, smart tablets, and smart phones, we often encounter the need to update the touch screen parameters for already shipped machines, especially for large-sized machines. The system partition requires a new ROM package to be recompiled for each update. To compile the ROM package, it needs to be fully compiled, which requires many developers and wastes a lot of time. The update ROM testing department needs to test the entire ROM package and close the burn. Recording a lot of test machines is a waste of time. From the user's point of view, app updates are also faster and more friendly than system updates. SUMMARY OF THE INVENTION [0003] In view of the deficiencies of the prior art, the present invention aims t...
