* Moved calls to Device mode Class Driver events to after the request has been ↵Dean Camera2010-08-221-1/+1
| | | | | | acknowledged, so that long event handlers do do skew the timing of the control requests. Fixed USBtoSerial and Benito project SetLineEncoding calls failing if the USART is busy, due to the RX ISR delaying the control request handler.
* Removed complicated logic for the Endpoint_ConfigureEndpoint() function to ↵Dean Camera2010-08-091-3/+4
| | | | | | use inlined or function called versions depending of if the given bank size is a compile time constant, as the compiler does a better job of optimizing with basic code. Changed over all device demos to use a clearer algorithm for the configuring of the application's endpoints.
* Fix XPLAINBridge project discarding characters from the USB interface due to ↵Dean Camera2010-08-011-7/+8
| | | | | | | | | | | | | | a double read from the endpoint. Make XPLAINBridge and USBtoSerial projects more reliable by forcing a flush if the UART-to-USB buffer becomes nearly full. Reduce locking in the LightweightRingBuffer.h header files by only locking on the update of the buffer count, and require insertions and removals from each buffer to occur in only one execution thread. Fix CDC_*_ReceiveByte() returning 0 when the interface is not configured, instead of the new -1 error value. Fix CDC_Host_ReceiveByte() not re-freezing the pipe if no packet has been received. Remove redundant Pipe token set commands in the CDC and RNDIS host class drivers.
* Fixed Serial peripheral driver not turning off the USART before ↵Dean Camera2010-07-311-1/+1

* Altered the CDC Deivice and Host Class drivers' receive byte routines, so ↵Dean Camera2010-07-301-7/+3
| | | | | | that no data is indicated by a negative return value. Added auto flushing of OUT data to the CDC Host Class driver's USBTask function to automatically flush the send pipe buffer.
* Oops - need to turn off USART via control register B before reconfiguring, ↵Dean Camera2010-07-301-2/+2
| | | | fix ordering of USART control register modifications in the Benito and USBtoSerial projects.
* Fixed Benito and USBtoSerial projects not turning off the USART before ↵Dean Camera2010-07-291-3/+10

* Fixed possible buffer overrun in the XPLAINBridge project when in serial ↵Dean Camera2010-07-151-1/+1

* Reduce prescaler of the flush timer in the USBtoSerial demo, so that buffer ↵Dean Camera2010-07-121-2/+2
| | | | overruns will not occur regardless of hardware and baud rate settings.
* Alter the ring buffer library headers to have both atomic and non-atomic ↵Dean Camera2010-07-121-7/+16
| | | | | | insertion/removal routines. Modify the existing projects so that buffer operations performed in an ISR use the shorted non-atomic versions, as they are already performed in a blocking ISR. Alter USBtoSerial demo so that it does not enter a blocking loop to send data from the USB to the USART, as this can cause dropped bytes in the reception code if large amounts of data are sent in both directions at the same time. Added a flush timer to the USBtoSerial code for the USART to USB interface, so that multiple bytes can be sent in the same USB packet.
* Replace ring buffer library in Benito and USBtoSerial projects with the new ↵Dean Camera2010-05-261-9/+9
| | | | lightweight ring buffer header to improve reliability.
* Add svn:eol-style property to source files, so that the line endings are ↵Dean Camera2010-05-081-198/+198
| | | | correctly converted to the target system's native end of line style.
* Change AVRISP project's timeout to be interrupt based again, but make the ↵Dean Camera2010-05-021-1/+1
| | | | | | interrupt itself interruptable and use a seperate assembly file to hand-optimize the ISR code. Removed the cast to uint16_t on the set baud rate in the USBtoSerial project, so that the higher >1M baud rates can be selected (thanks to Steffan).
* USB_Init() no longer calls sei() to enable global interrupts - this must now ↵Dean Camera2010-04-281-0/+1
| | | | be done in the user application once all init code has run.
* Increased throughput of the USBtoSerial demo on systems that send multiple ↵Dean Camera2010-03-161-2/+2

* Add double banking property to LUFA powered projects in the Projects ↵Dean Camera2009-11-061-7/+10

* Use clearer buffer names in the USBtoSerial project to prevent confusion.Dean Camera2009-10-261-11/+11

CDC demo. Added const qualifier to Endpoint/Pipe stream write routines.
