* Update copyright year on all source files.Dean Camera2011-01-011-2/+2
|
* Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org ↵Dean Camera2010-10-281-1/+1
| | | | redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists.
* All USB class drivers are now automatically included when LUFA/Drivers/USB.h ↵Dean Camera2010-10-241-0/+1
| | | | | | is included, and no longer need to be seperately included. All LowLevel demos changed to use the constants and types defined in the USB class drivers.
* Clean up excessive whitespace at the end of each line using the wspurify ↵Dean Camera2010-10-131-10/+10
| | | | tool made by Laszlo Monda
* Reverted Endpoint/Pipe non-sequential configuration hack, placed restriction ↵Dean Camera2010-09-301-12/+21
| | | | | | | | | | on the configuration order instead to ensure maximum reliability. Altered all low level device and host mode demos to ensure that endpoints and pipes are configured in ascending order properly. Rewrote all low level host mode demos' configuration descriptor parser code to ensure that pipes are enumerated in ascending order, and to ensure maximum compatibility with devices. Incremented all device mode demo's device descriptor revision numbers to ensure that any descriptor changes are re-fetched on machines which have enumerated previous versions.
* Changed all Device mode LowLevel demos and Device Class drivers so that the ↵Dean Camera2010-08-221-3/+2
| | | | control request is acknowledged and any data transferred as quickly as possible without any processing inbetween sections, so that long callbacks or event handlers will not break communications with the host by exceeding the maximum control request stage timeout period.
* Add missing const qualifiers to class drivers.Dean Camera2010-07-211-1/+1
| | | | Indent core library function parameters so that there is only one parameter per line, to increase readability.
* Add svn:eol-style property to source files, so that the line endings are ↵Dean Camera2010-05-081-88/+88
| | | | correctly converted to the target system's native end of line style.
* The Audio_Device_IsSampleReceived() and Audio_Device_IsReadyForNextSample() ↵Dean Camera2010-04-291-18/+0
| | | | functions are now inline, to reduce overhead.
* Add more include protection macros to give the user warnings when they try ↵Dean Camera2010-02-111-0/+2
| | | | to manually include private driver header files, instead of the public driver headers.
* Inline USB management functions in the Class drivers which are standardized ↵Dean Camera2010-01-051-5/+0
| | | | but currently unused, to prevent them from using up unneccesary cycles and flash in the user application.
* Update copyright year to 2010.Dean Camera2009-12-301-2/+2
|
* Fix MIT license language to make its intent clearer.Dean Camera2009-12-281-7/+7
|
* Test with -Wextra, fix library warnings due to unused function parameters.Dean Camera2009-12-131-1/+1
|
* Add optional pipe double banking support to the Host mode Class drivers.Dean Camera2009-11-071-1/+1
| | | | Descriptor processing routines now pass around void pointers rather than uint8_t pointers, as their destination datatype is know well known -- they are just streams of bytes until they are cast to the correct destination type by DESCRIPTOR_CAST.
* Changed Audio Class driver sample read/write functions to be inline, to ↵Dean Camera2009-10-031-61/+0
| | | | | | reduce the number of cycles needed to transfer samples to and from the device (allowing more time for processing and output). Fixed ClassDriver AudioOutput demo not selecting an audio output mode.
* Renamed all library events to properly seperate out Device and Host mode ↵Dean Camera2009-08-051-1/+1
| | | | | | | | events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only. Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events. Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.
* Fix incorrect configuration in the ClassDriver AudioOutput demo.Dean Camera2009-07-301-13/+19
| | | | | | 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.
* State information for class drivers is now zeroed out during enumeration ↵Dean Camera2009-07-271-1/+3
| | | | (both in device and host mode) to ensure sane values after each enumeration. User code should no longer explicitly set state information as this is no longer preserved.
* Added new USB_DeviceState variable to keep track of the current Device mode ↵Dean Camera2009-07-211-2/+1
| | | | | | | | | | | | USB state. Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers. 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. Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.
* Added const modifiers to device mode class drivers.Dean Camera2009-06-281-7/+7
| | | | | | Added parameter directions to function parameter documentation. Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).
* Break device mode class driver interfaces into seperate config and state ↵Dean Camera2009-06-181-15/+15
| | | | structs which are then combined, for clarity. Move device mode class driver interfaces back into the device mode class driver headers from the common class headers to make room for host class interfaces.
* Add host mode USB Class driver stubs, add beginnings of a CDC host class driver.Dean Camera2009-06-141-0/+5
| | | | | | Split out common defines/types from class drivers into a seperate common class driver directory. Make central USB Class driver dispatch headers, used for both device and host modes.
* Changed to new device mode Class Driver function name prefixes to make way ↵Dean Camera2009-06-111-11/+11
| | | | for similar host mode Class drivers.
* Ensure all USB device class drivers have the same three main functions as ↵Dean Camera2009-06-041-0/+5
| | | | their interface for consistency.
* Minor documentation page updates.Dean Camera2009-06-041-1/+1
| | | | | | | | Redocumented all device demos, now that they have changed over to the new USB class drivers. Added C linkage to class drivers for C++ support. Added prefixes to most of the class driver constants to prevent name clashes.
* Add MIDI class driver, update MIDI device demo to use the new USB class ↵Dean Camera2009-06-011-2/+2
| | | | driver. All device demos/projects have now been converted to the new library class drivers, although documentation is yet to be completed.
* Commit of new class abstraction APIs for all device demos other than the ↵Dean Camera2009-06-011-0/+154
MIDI demo - not documented yet. Removed scheduler and memory allocation libraries. Added new EVENT_USB_StartOfFrame event in the library to indicate the start of each USB frame (when generated). Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt.
