Switch bit-bang USART in the AVRISP project to Timer 1, so that Timer 0 can be used for hardware timeouts while waiting for the NVM bus or controller to become ready.Added memory erase handling to the PDI protocol in the AVRISP project.Fix NVM commands so that memory reads and CRC generations now work correctly using unoptimized PDI commands.Split out NVM access code in the AVRISP project into a seperate NVMTarget.c source file and header. Make NVM register accesses use the NVM base address as set by the host, rather than using the fixed value from the XMEGA datasheet.Test with -Wextra, fix library warnings due to unused function parameters.Oops - wrong casting on the Configuration Descriptor pointer advance routine.Use -pedantic compile time option to find and correct several minor code errors.The AVRISP project can now enter PDI mode under both bit-bang and hardware USART connection modes, tested against the XPLAIN board hardware. Still need to complete higher level NVM access code so that the device's memories can be read and written.PDI NVM enable is fast enough that bare polling is enough without a fixed delay in between each attempt. Make sure the USART transmitter is enabled explicitly when the USART is configured, so that repeated attempts to re-enter PDI mode don't fail due to TXEN not being set.Fix PDI code - must send NVM enable key least significant byte first, need to make sure Tx and Rx is switched correctly including disabling the output on the Tx line when receiving.Fix AVRISP PDI protocol - make sure inverted masks have the appropriate parenthesis around them, make sure the BREAK command for the hardware USART has 12 clock cycles exactly. Poll NVM Enable bit in the target's STATUS PDI register with a timeout, as it is not set immediately.Change over AVRISP project to have both hardware USART and software USART modes for the PDI protocol, when enabled. Fix up PDI initialisation routines.Fix PDITarget_ReceiveByte() not discarding the start bit properly, and reading in the bits inverted and in the wrong order.Add even parity bit to the software USART framing in the AVRISP project's PDI programming code.Fix inverted bit-banged USART logic in the AVRISP project for PDI programming. Add a delay to the clock toggling in the AVRISP project to ensure that the programming speed does not exceed 10MHz under any conditions to satisfy the limits in the datasheet for all target voltages. Fix incorrect pin being used as the DATA in in PDI programming mode.Fix incorrect definition of Endpoint_BytesInEndpoint() for the U4 parts.Increase timeout of Mass Storage and Still Image host commands to 10 seconds (up from 5) to account for slow-processing devices.Make sure that USB_STREAM_TIMEOUT_MS is set in the MassStorageHost ClassDriver demo, so that slow devices don't time out the data pipe. Increase pipe timeout in both MassStorageHost demos to 5 seconds to account for the really slow devices.Fix newly renamed VirtualSerial demos' include filename references so that they compile.Additional file renames and modifications to change CDC demos to VirtualSerial.Rename CDC demos to VirtualSerial.Add new USB_Host_GetDeviceStringDescriptor() convenience function.Fixed Mass Storage Host Class driver and Low Level demo not clearing the error condition if an attached device returns a STALL to a GET MAX LUN request (thanks to Martin Luxen).Added support for the Atmel EVK527 board hardware.Fix double oops -- Host mode settle delay was still being ignored due to inverted logic, HID Parser was assigning the usage Min/Max usage value to the report item's collection path rather than the report item itself.Oops - fix Host mode pre-enumeration settle delay being ignored leading to failure to enumerate certain devices.Fix incorrect const'ness of the ReportItem parameter in USB_SetHIDReportItemInfo().Fixed HID Parser not distributing the Usage Min and Usage Max values across an array of report items.Make sure the protocol handler files are included in the Doxygen documentation of the AVRISP project.Fix the tokens which enable and disable the different programming protocols in the AVRISP project.Added support for the Dataflash mounted on the XPLAIN board. Added new XPLAIN_REV1 board target for the first revision XPLAIN board, which used a different (smaller) Dataflash IC to later revisions.Auto-configure AVRISP programmer configuration when built for the XPLAIN board to match the XPLAIN hardware connections.Document the PDI programming routines implemented so far in the AVRISP project. Add ability to selectively disable ISP programming support in addition to the existing ability to disable PDI programming support.
