Gpio button driver implementation guide

 · GpioClx calls event callback functions that are implemented by the GPIO controller driver. The GPIO controller driver directly accesses the hardware registers of the GPIO controller device. GpioClx handles I/O requests from the drivers for peripheral devices that physically connect to GPIO pins. GpioClx translates these I/O requests into simple hardware . 7 rows ·  · Windows 8 introduced support for general-purpose I/O (GPIO) buttons and indicators by using a HID.  · The in-box general-purpose I/O (GPIO) button driver reports to Windows, based on the interrupts that are received on the defined GPIO resources of the button array. The in-box GPIO button driver reports the button presses and combinations listed in Table 1 .

The official Windows Driver Kit documentation sources - windows-driver-docs/gpio-buttons-and-indicators-implementation-guide-for-windowsmd at staging. The in-box general-purpose I/O (GPIO) button driver reports to Windows, based on the interrupts that are received on the defined GPIO resources of the button array. The in-box GPIO button driver reports the button presses and combinations listed in Table 1 GPIO Button Reporting. In this article. We recommend that you use a physical GPIO resource for both the buttons and state indicators. On systems that do not have a physical GPIO resource for a required/optional hardware button or for a GPIO indicator (laptop/slate mode indication or docked indication), a user mode or kernel mode driver can inject state changes directly to the inbox driver instead of a physical.
