Method for realizing android upper layer driving IO and related products

Abstract

A method for realizing android upper layer driving IO and related products are provided. The method comprises the following steps: when the system starts the kernel, loading the preset GPIO driver torealize the preset IOCTL operation, wherein the IOCTL operation comprises: acquiring the current GPIO state, acquiring the usable GPIO quantity and setting the GPIO state; loading a preset daemon process for realizing communication between the GPIO driver and the android upper layer driver IO and providing an access interface for the android framework, wherein the interface is used for setting thecorresponding GPIO through the service and the daemon. The technical solution provided by the present application has the advantage of high flexibility.

Benefits of technology

This technology allows for more flexible customization options within an operating system (OS). By placing certain features onto applications rather than modifying them yourself, it becomes easier to modify or enhance these capabilities without affecting their original purpose.

Problems solved by technology

The problem with current methods where an external interface (GPIO) can be used by embedding electronic components like Android has been that updating software on these interfaces requires continuous intervention from users who are no longer able to access them due to their changing needs. This makes upgrading new features difficult without requiring constant maintenance efforts.
