From 41babf1cb78a2a8e05f40f5de61c3f52bb794fc4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix incorrect configuration in the ClassDriver AudioOutput
demo.
Make all audio device Class Driver functions require a reference to the Audio class instance, so that the endpoint size can be checked (and to standardize the APIs).
Make LEDs more responsive in the AudioOutput device demos.

* <b>New:</b>
* - Added new class drivers and matching demos to the library for rapid application development
+ * - Added new PrinterHost demo (thanks to John Andrews)
+ * - Added USB Missle Launcher project, submitted by Dave Fletcher
+ * - Added new Benito Arduino Programmer project
* - Added incomplete device and host mode demos for later enhancement
+ * - Updated MassStorage device block write routines to use ping-pong Dataflash buffering to increase throughput by around 30%
* - Error status LEDs shown when device endpoint configuration fails to complete in all demos and projects
* - Added new USB_Host_SetDeviceConfiguration() convenience function for easy configuration selection of devices while in USB
* host mode
* - Added new USB_Host_ClearPipeStall() convenience function to clear a stall condition on an attached device's endpoint
* - Added new USB_Host_GetDeviceDescriptor() convenience function to retrieve the attached device's Device descriptor
- * - Added USB Missle Launcher project, submitted by Dave Fletcher
+ * - Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers
* - Added new USE_INTERNAL_SERIAL define for using the unique serial numbers in some AVR models as the USB device's serial number,
* added NO_INTERNAL_SERIAL compile time option to turn off new serial number reading code
* - Added new DATAFLASH_CHIP_MASK() macro to the Dataflash driver, which returns the Dataflash select mask for the given chip index
- * - Updated MassStorage device block write routines to use ping-pong Dataflash buffering to increase throughput by around 30%
* - Added new HOST_STATE_WaitForDeviceRemoval host state machine state for non-blocking disabling of device communications until the
* device has been removed (for use when an error occurs or communications with the device have completed)
* - Added new FAST_STREAM_TRANSFERS compile time option for faster stream transfers via multiple bytes copied per stream loop
- * - Added stdio stream demo code to the low-level CDC demo, to show how to create standard streams out of the virtual serial ports
+ * - Added stdio stream demo code to the CDC device demos, to show how to create standard streams out of the virtual serial ports
* - Added new EEPROM and FLASH buffer versions of the Endpoint and Pipe stream functions
* - Added new USE_FLASH_DESCRIPTORS and TOTAL_NUM_CONFIGURATIONS compile time options
* - Added support for the new ATMEGA32U2, ATMEGA16U2 and ATMEGA8U2 AVR models

* - Added new USB_DeviceState variable to keep track of the current Device mode USB state
- * - Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers
- * - Added new Benito Arduino Programmer project
* - Added new LEDs_ToggleLEDs() function to the LEDs driver
* - Added new Pipe_BoundEndpointNumber() and Pipe_IsEndpointBound() functions

- * - Added 404 errors to the Webserver in the RNDIS demos to indicate invalid URLs
+ * - Added 404 Not Found errors to the webserver in the RNDIS demos to indicate invalid URLs
*
* <b>Changed:</b>
* - Deprecated psuedo-scheduler and removed dynamic memory allocator from the library (first no longer needed and second unused)
+ * - The device-mode CALLBACK_USB_GetDescriptor() function now has an extra parameter so that the memory space in which the requested
+ * descriptor is located can be specified. This means that descriptors can now be located in multiple memory spaces within a device.
+ * - Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality
+ * - Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead
+ * - Extended USB_GetDeviceConfigDescriptor() routine to require the configuration number within the device to fetch
+ * - Dataflash_WaitWhileBusy() now always ensures that the dataflash is ready for the next command immediately after returning,
+ * no need to call Dataflash_ToggleSelectedChipCS() afterwards
* - Low level API MIDI device demo no longer blocks if a note change event is sent while the endpoint is not ready
- * - Internal per-device preprocessing conditions changed to per-device series rather than per controller group for finer-grain
- * internal control
* - Pipe_GetErrorFlags() now returns additional error flags for overflow and underflow errors
- * - Extended USB_GetDeviceConfigDescriptor() routine to require the configuration number within the device to fetch
* - Pipe stream functions now automatically set the correct pipe token, so that bidirectional pipes can be used
* - Pipe_ConfigurePipe() now automatically defaults IN pipes to accepting infinite IN requests, this can still be changed by calling
* the existing Pipe_SetFiniteINRequests() function
- * - Dataflash_WaitWhileBusy() now always ensures that the dataflash is ready for the next command immediately after returning,
- * no need to call Dataflash_ToggleSelectedChipCS() afterwards
* - Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case
- * - The device-mode CALLBACK_USB_GetDescriptor() function now has an extra parameter so that the memory space in which the requested
- * descriptor is located can be specified. This means that descriptors can now be located in multiple memory spaces within a device.
* - Host mode demos now use sane terminal escape codes, so that text is always readable and events/program output is visually distinguished
* from oneanother using foreground colours
- * - Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality
- * - Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead
+ * - Internal per-device preprocessing conditions changed to per-device series rather than per-controller group for finer-grain
+ * internal control
*
* <b>Fixed:</b>
* - Changed bootloaders to use FLASHEND rather than the existence of RAMPZ to determine if far FLASH pointers are needed to fix
