Detailed Description

USB event handler functions used during enumeration and operation of the device stack.

Field Documentation

pfnGetDescriptor

tStdRequest tCustomHandlers::pfnGetDescriptor

This callback is made whenever the USB host requests a non-standard descriptor from the device.

pfnRequestHandler

tStdRequest tCustomHandlers::pfnRequestHandler

This callback is made whenever the USB host makes a non-standard request.

pfnInterfaceChange

tInterfaceCallback tCustomHandlers::pfnInterfaceChange

This callback is made in response to a SetInterface request from the host.

pfnConfigChange

tInfoCallback tCustomHandlers::pfnConfigChange

This callback is made in response to a SetConfiguration request from the host.

pfnDataReceived

tInfoCallback tCustomHandlers::pfnDataReceived

This callback is made when data has been received following to a call to USBDCDRequestDataEP0.

pfnDataSent

tInfoCallback tCustomHandlers::pfnDataSent

This callback is made when data has been transmitted following a call to USBDCDSendDataEP0.

pfnResetHandler

tUSBIntHandler tCustomHandlers::pfnResetHandler

This callback is made when a USB reset is detected.

Referenced by USBDeviceEnumResetHandler().

pfnSuspendHandler

tUSBIntHandler tCustomHandlers::pfnSuspendHandler

This callback is made when the bus has been inactive long enough to trigger a suspend condition.

Referenced by USBDeviceIntHandlerInternal().

pfnResumeHandler

tUSBIntHandler tCustomHandlers::pfnResumeHandler

This is called when resume signaling is detected.

Referenced by USBDeviceIntHandlerInternal(), and USBDeviceResumeTickHandler().

pfnDisconnectHandler

tUSBIntHandler tCustomHandlers::pfnDisconnectHandler

This callback is made when the device is disconnected from the USB bus.

Referenced by USBDeviceIntHandlerInternal().

pfnEndpointHandler

tUSBEPIntHandler tCustomHandlers::pfnEndpointHandler

This callback is made to inform the device of activity on all endpoints other than endpoint zero.

Referenced by USBDeviceIntHandlerInternal().

pfnDeviceHandler

tUSBDeviceHandler tCustomHandlers::pfnDeviceHandler

This generic handler is provided to allow requests based on a given instance to be passed into a device. This is commonly used by a top level composite device that is using multiple instances of a class.
