Each Device mode Class driver typically contains a set of configuration parameters + * for the endpoint size/number of the associated logical USB interface, plus any class-specific configuration parameters. + * + * The following is an example of a properly initialized instance of the Audio Class Driver structure: + * + * \code + * USB_ClassInfo_Audio_Device_t My_Audio_Interface = + * { + * .Config = + * { + * .StreamingInterfaceNumber = 1, + * .DataINEndpoint = + * { + * .Address = (ENDPOINT_DIR_IN | 1), + * .Size = 64, + * .Banks = 1, + * }, + * }, + * }; + * \endcode + * + * \note The class driver's configuration parameters should match those used in the device's descriptors that are + * sent to the host. + * + * To initialize the Class driver instance, the driver's <tt><i>{Class Name}</i>_Device_ConfigureEndpoints()</tt> function + * should be called in response to the \ref EVENT_USB_Device_ConfigurationChanged() event. This function will return a + * boolean true value if the driver successfully initialized the instance. Like all the class driver functions, this function + * takes in the address of the specific instance you wish to initialize - in this manner, multiple separate instances of + * the same class type can be initialized like this: + * + * \code + * void EVENT_USB_Device_ConfigurationChanged(void) + * { + * LEDs_SetAllLEDs(LEDMASK_USB_READY); + * + * if (!(Audio_Device_ConfigureEndpoints(&My_Audio_Interface))) + * LEDs_SetAllLEDs(LEDMASK_USB_ERROR); + * } + * \endcode + * + * Once initialized, it is important to maintain the class driver's state by repeatedly calling the Class Driver's + * <tt><i>{Class Name}</i>_Device_USBTask()</tt> function in the main program loop. The exact implementation of this + * function varies between class drivers, and can be used for any internal class driver purpose to maintain each + * instance. Again, this function uses the address of the instance to operate on, and thus needs to be called for each + * separate instance, just like the main USB maintenance routine \ref USB_USBTask(): + * + * \code + * int main(void) + * { + * SetupHardware(); + * + * LEDs_SetAllLEDs(LEDMASK_USB_NOTREADY); + * + * for (;;) + * { + * if (USB_DeviceState != DEVICE_STATE_Configured) + * Create_And_Process_Samples(); + * + * Audio_Device_USBTask(&My_Audio_Interface); + * USB_USBTask(); + * } + * } + * \endcode + * + * The final standardized Device Class Driver function is the Control Request handler function + * <tt><i>{Class Name}</i>_Device_ProcessControlRequest()</tt>, which should be called when the + * \ref EVENT_USB_Device_ControlRequest() event fires. This function should also be called for + * each class driver instance, using the address of the instance to operate on as the function's + * parameter. The request handler will abort if it is determined that the current request is not + * targeted at the given class driver instance, thus these methods can safely be called + * one-after-another in the event handler with no form of error checking: + * + * \code + * void EVENT_USB_Device_ControlRequest(void) + * { + * Audio_Device_ProcessControlRequest(&My_Audio_Interface); + * } + * \endcode + * + * Each class driver may also define a set of callback functions (which are prefixed by \c CALLBACK_* + * in the function's name) which <b>must</b> also be added to the user application - refer to each + * individual class driver's documentation for mandatory callbacks. In addition, each class driver may + * also define a set of events (identifiable by their prefix of \c EVENT_* in the function's name), which + * the user application <b>may</b> choose to implement, or ignore if not needed. + * + * The individual Device Mode Class Driver documentation contains more information on the non-standardized, + * class-specific functions which the user application can then use on the driver instances, such as data + * read and write routines. See each driver's individual documentation for more information on the + * class-specific functions. + * + * \subsection Sec_USB_ClassDriverHost Host Mode Class Drivers + * Implementing a Host Mode Class Driver in a user application requires a number of steps to be followed. Firstly, + * the module configuration and state structure must be added to the project source. These structures are named in a + * similar manner between classes, that of <tt>USB_ClassInfo_<b>{Class Name}</b>_Host_t</tt>, and are used to hold the + * complete state and configuration for each class instance. Multiple class instances is where the power of the class + * drivers lie; multiple interfaces of the same class simply require more instances of the Class Driver's \c USB_ClassInfo_* + * structure. + * + * Inside the \c USB_ClassInfo_* structure lies two sections, a \c Config section, and a \c State section. The \c Config + * section contains the instance's configuration parameters, and <b>must have all fields set by the user application</b> + * before the class driver is used. Each Device mode Class driver typically contains a set of configuration parameters + * for the endpoint size/number of the associated logical USB interface, plus any class-specific configuration parameters. + * + * The following is an example of a properly initialized instance of the MIDI Host Class Driver structure: + * + * \code + * USB_ClassInfo_MIDI_Host_t My_MIDI_Interface = + * { + * .Config = + * { + * .DataINPipe = + * { + * .Address = (PIPE_DIR_IN | 1), + * .Size = 64, + * .Banks = 1, + * }, + * .DataOUTPipe = + * { + * .Address = (PIPE_DIR_OUT | 2), + * .Size = 64, + * .Banks = 1, + * }, + * }, + * }; + * \endcode + * + * To initialize the Class driver instance, the driver's <tt><b>{Class Name}</b>_Host_ConfigurePipes()</tt> function + * should be called in response to the \c EVENT_USB_Host_DeviceEnumerationComplete() event firing. This function will + * will return an error code from the class driver's <tt><b>{Class Name}</b>_EnumerationFailure_ErrorCodes_t</tt> enum + * to indicate if the driver successfully initialized the instance and bound it to an interface in the attached device. + * Like all the class driver functions, this function takes in the address of the specific instance you wish to initialize - + * in this manner, multiple separate instances of the same class type can be initialized. A fragment of a Class Driver + * based Host mode application may look like the following: + * + * \code + * void EVENT_USB_Host_DeviceEnumerationComplete(void) + * { + * LEDs_SetAllLEDs(LEDMASK_USB_ENUMERATING); + * + * uint16_t ConfigDescriptorSize; + * uint8_t ConfigDescriptorData[512]; + * + * if (USB_Host_GetDeviceConfigDescriptor(1, &ConfigDescriptorSize, ConfigDescriptorData, + * sizeof(ConfigDescriptorData)) != HOST_GETCONFIG_Successful) + * { + * LEDs_SetAllLEDs(LEDMASK_USB_ERROR); + * return; + * } + * + * if (MIDI_Host_ConfigurePipes(&Keyboard_MIDI_Interface, + * ConfigDescriptorSize, ConfigDescriptorData) != MIDI_ENUMERROR_NoError) + * { + * LEDs_SetAllLEDs(LEDMASK_USB_ERROR); + * return; + * } + * + * if (USB_Host_SetDeviceConfiguration(1) != HOST_SENDCONTROL_Successful) + * { + * LEDs_SetAllLEDs(LEDMASK_USB_ERROR); + * return; + * } + * + * LEDs_SetAllLEDs(LEDMASK_USB_READY); + * } + * \endcode + * + * Note that the function also requires the device's configuration descriptor so that it can determine which interface + * in the device to bind to - this can be retrieved as shown in the above fragment using the + * \ref USB_Host_GetDeviceConfigDescriptor() function. If the device does not implement the interface the class driver + * is looking for, if all the matching interfaces are already bound to class driver instances or if an error occurs while + * binding to a device interface (for example, a device endpoint bank larger that the maximum supported bank size is used) + * the configuration will fail. + * + * To complete the device enumeration after binding the host mode Class Drivers to the attached device, a call to + * \c USB_Host_SetDeviceConfiguration() must be made. If the device configuration is not set within the + * \c EVENT_USB_Host_DeviceEnumerationComplete() event, the host still will assume the device enumeration has failed. + * + * Once initialized, it is important to maintain the class driver's state by repeatedly calling the Class Driver's + * <tt><b>{Class Name}</b>_Host_USBTask()</tt> function in the main program loop. The exact implementation of this + * function varies between class drivers, and can be used for any internal class driver purpose to maintain each + * instance.
