GpioClx Event Callback Functions

This section describes the event callback functions that are defined by the GPIO framework extension (GpioClx). These functions are implemented by the GPIO controller driver. GpioClx calls these functions to perform I/O operations through GPIO pins and to manage GPIO interrupts. These event callback functions are defined in the Gpioclx.h header file.

Topic	Description
CLIENT_ClearActiveInterrupts	The CLIENT_ClearActiveInterrupts event callback function clears active interrupts on a set of general-purpose I/O (GPIO) pins that are configured as interrupt inputs.
CLIENT_ConnectIoPins	The CLIENT_ConnectIoPins event callback function opens a logical connection to a set of general-purpose I/O (GPIO) pins and configures these pins for data read or write operations.
CLIENT_ControllerSpecificFunction	The CLIENT_ControllerSpecificFunction event callback function performs an operation that is specific to a particular general-purpose I/O (GPIO) controller.
CLIENT_DisableInterrupt	The CLIENT_DisableInterrupt event callback function disables interrupts on a general-purpose I/O (GPIO) pin that is configured as an interrupt input.
CLIENT_DisconnectIoPins	The CLIENT_DisconnectIoPins event callback function closes a logical connection to a set of general-purpose I/O (GPIO) pins that are configured for data read or write operations.
CLIENT_EnableInterrupt	The CLIENT_EnableInterrupt event callback function enables interrupts on a general-purpose I/O (GPIO) pin that is configured as an interrupt input.
CLIENT_MaskInterrupts	The CLIENT_MaskInterrupts event callback function masks interrupts on a set of general-purpose I/O (GPIO) pins that are configured as interrupt inputs.
CLIENT_PrepareController	The CLIENT_PrepareController event callback function performs any operations that are needed to make the general-purpose I/O (GPIO) controller ready to be accessed by the GPIO controller driver.
CLIENT_PreProcessControllerInterrupt	The CLIENT_PreProcessControllerInterrupt event callback function performs any pre-processing of a general-purpose I/O (GPIO) interrupt that must be done immediately if the ISR is scheduled to run at a later time.
CLIENT_QueryActiveInterrupts	The CLIENT_QueryActiveInterrupts event callback function queries the state of a set of general-purpose I/O (GPIO) pins that are configured as interrupt inputs.
CLIENT_QueryControllerBasicInformation	The CLIENT_QueryControllerBasicInformation event callback function retrieves the hardware attributes of the general-purpose I/O (GPIO) controller.
CLIENT_QueryEnabledInterrupts	The CLIENT_QueryEnabledInterrupts event callback function queries the state of a set of general-purpose I/O (GPIO) pins to determine which pins are both configured as interrupt inputs and enabled for interrupts.
CLIENT_QuerySetControllerInformation	The CLIENT_QuerySetControllerInformation event callback function queries the general-purpose I/O (GPIO) controller driver for the specified set of attributes of the GPIO controller.
CLIENT_ReadGpioPins	The CLIENT_ReadGpioPins event callback function reads a set of general-purpose I/O (GPIO) pins that are configured as data inputs.
CLIENT_ReadGpioPinsUsingMask	The CLIENT_ReadGpioPinsUsingMask event callback function reads a bank of general-purpose I/O (GPIO) pins.
CLIENT_ReconfigureInterrupt	The CLIENT_ReconfigureInterrupt event callback function reconfigures a general-purpose I/O (GPIO) pin that is used as an interrupt input.
CLIENT_ReleaseController	The CLIENT_ReleaseController event callback function performs operations that are needed when the general-purpose I/O (GPIO) controller device is no longer accessible.
CLIENT_RestoreBankHardwareContext	The CLIENT_RestoreBankHardwareContext event callback function restores the hardware context of a bank of general-purpose I/O (GPIO) pins.
CLIENT_SaveBankHardwareContext	The CLIENT_SaveBankHardwareContext event callback function saves the hardware context of a bank of general-purpose I/O (GPIO) pins.
CLIENT_StartController	The CLIENT_StartController event callback function performs operations that are needed when the general-purpose I/O (GPIO) controller device enters the D0 power state.
CLIENT_StopController	The CLIENT_StopController event callback function performs operations that are needed to prepare the general-purpose I/O (GPIO) controller device to exit the D0 power state.
CLIENT_UnmaskInterrupt	The CLIENT_UnmaskInterrupt event callback function unmasks the interrupt on a general-purpose I/O (GPIO) pin that is configured as an interrupt input.
CLIENT_WriteGpioPins	The CLIENT_WriteGpioPins event callback function writes to a set of general-purpose I/O (GPIO) pins that are configured as data outputs.
CLIENT_WriteGpioPinsUsingMask	The CLIENT_WriteGpioPinsUsingMask event callback function writes to a set of general-purpose I/O (GPIO) pins that are configured as data outputs.
