New entries are always appended to the end of the file. -Scroll down to the bottom to see the most recent changes. - -2005-04-01: - - Implemented endpoint 1 as interrupt-in endpoint. - - Moved all configuration options to usbconfig.h which is not part of the - driver. - - Changed interface for usbVendorSetup(). - - Fixed compatibility with ATMega8 device. - - Various minor optimizations. - -2005-04-11: - - Changed interface to application: Use usbFunctionSetup(), usbFunctionRead() - and usbFunctionWrite() now. Added configuration options to choose which - of these functions to compile in. - - Assembler module delivers receive data non-inverted now. - - Made register and bit names compatible with more AVR devices. - -2005-05-03: - - Allow address of usbRxBuf on any memory page as long as the buffer does - not cross 256 byte page boundaries. - - Better device compatibility: works with Mega88 now. - - Code optimization in debugging module. - - Documentation updates. - -2006-01-02: - - Added (free) default Vendor- and Product-IDs bought from voti.nl. - - Added USBID-License.txt file which defines the rules for using the free - shared VID/PID pair. - - Added Readme.txt to the usbdrv directory which clarifies administrative - issues. - -2006-01-25: - - Added "configured state" to become more standards compliant. - - Added "HALT" state for interrupt endpoint. - - Driver passes the "USB Command Verifier" test from usb.org now. - - Made "serial number" a configuration option. - - Minor optimizations, we now recommend compiler option "-Os" for best - results. - - Added a version number to usbdrv.h - -2006-02-03: - - New configuration variable USB_BUFFER_SECTION for the memory section where - the USB rx buffer will go. This defaults to ".bss" if not defined. Since - this buffer MUST NOT cross 256 byte pages (not even touch a page at the - end), the user may want to pass a linker option similar to - "-Wl,--section-start=.mybuffer=0x800060". - - Provide structure for usbRequest_t. - - New defines for USB constants. - - Prepared for HID implementations. - - Increased data size limit for interrupt transfers to 8 bytes. - - New macro usbInterruptIsReady() to query interrupt buffer state. - -2006-02-18: - - Ensure that the data token which is sent as an ack to an OUT transfer is - always zero sized. This fixes a bug where the host reports an error after - sending an out transfer to the device, although all data arrived at the - device. - - Updated docs in usbdrv.h to reflect changed API in usbFunctionWrite(). - -* Release 2006-02-20 - - - Give a compiler warning when compiling with debugging turned on. - - Added Oleg Semyonov's changes for IAR-cc compatibility. - - Added new (optional) functions usbDeviceConnect() and usbDeviceDisconnect() - (also thanks to Oleg!). - - Rearranged tests in usbPoll() to save a couple of instructions in the most - likely case that no actions are pending. - - We need a delay between the SET ADDRESS request until the new address - becomes active. This delay was handled in usbPoll() until now. Since the - spec says that the delay must not exceed 2ms, previous versions required - aggressive polling during the enumeration phase. We have now moved the - handling of the delay into the interrupt routine. - - We must not reply with NAK to a SETUP transaction. We can only achieve this - by making sure that the rx buffer is empty when SETUP tokens are expected. - We therefore don't pass zero sized data packets from the status phase of - a transfer to usbPoll(). This change MAY cause troubles if you rely on - receiving a less than 8 bytes long packet in usbFunctionWrite() to - identify the end of a transfer. usbFunctionWrite() will NEVER be called - with a zero length. - -* Release 2006-03-14 - - - Improved IAR C support: tiny memory model, more devices - - Added template usbconfig.h file under the name usbconfig-prototype.h - -* Release 2006-03-26 - - - Added provision for one more interrupt-in endpoint (endpoint 3). - - Added provision for one interrupt-out endpoint (endpoint 1). - - Added flowcontrol macros for USB. - - Added provision for custom configuration descriptor. - - Allow ANY two port bits for D+ and D-. - - Merged (optional) receive endpoint number into global usbRxToken variable. - - Use USB_CFG_IOPORTNAME instead of USB_CFG_IOPORT. We now construct the - variable name from the single port letter instead of computing the address - of related ports from the output-port address. - -* Release 2006-06-26 - - - Updated documentation in usbdrv.h and usbconfig-prototype.h to reflect the - new features. - - Removed "#warning" directives because IAR does not understand them. Use - unused static variables instead to generate a warning. - - Do not include <avr/io.h> when compiling with IAR. - - Introduced USB_CFG_DESCR_PROPS_* in usbconfig.h to configure how each - USB descriptor should be handled. It is now possible to provide descriptor - data in Flash, RAM or dynamically at runtime. - - STALL is now a status in usbTxLen* instead of a message. We can now conform - to the spec and leave the stall status pending until it is cleared. - - Made usbTxPacketCnt1 and usbTxPacketCnt3 public. This allows the - application code to reset data toggling on interrupt pipes. - -* Release 2006-07-18 - - - Added an #if !defined __ASSEMBLER__ to the warning in usbdrv.h. This fixes - an assembler error. - - usbDeviceDisconnect() takes pull-up resistor to high impedance now. - -* Release 2007-02-01 - - - Merged in some code size improvements from usbtiny (thanks to Dick - Streefland for these optimizations!) - - Special alignment requirement for usbRxBuf not required any more. Thanks - again to Dick Streefland for this hint! - - Reverted to "#warning" instead of unused static variables -- new versions - of IAR CC should handle this directive. - - Changed Open Source license to GNU GPL v2 in order to make linking against - other free libraries easier. We no longer require publication of the - circuit diagrams, but we STRONGLY encourage it. If you improve the driver - itself, PLEASE grant us a royalty free license to your changes for our - commercial license. - -* Release 2007-03-29 - - - New configuration option "USB_PUBLIC" in usbconfig.h. - - Set USB version number to 1.10 instead of 1.01. - - Code used USB_CFG_DESCR_PROPS_STRING_DEVICE and - USB_CFG_DESCR_PROPS_STRING_PRODUCT inconsistently. Changed all occurrences - to USB_CFG_DESCR_PROPS_STRING_PRODUCT. - - New assembler module for 16.5 MHz RC oscillator clock with PLL in receiver - code. - - New assembler module for 16 MHz crystal. - - usbdrvasm.S contains common code only, clock-specific parts have been moved - to usbdrvasm12.S, usbdrvasm16.S and usbdrvasm165.S respectively. - -* Release 2007-06-25 - - - 16 MHz module: Do SE0 check in stuffed bits as well. - -* Release 2007-07-07 - - - Define hi8(x) for IAR compiler to limit result to 8 bits. This is necessary - for negative values. - - Added 15 MHz module contributed by V. Bosch. - - Interrupt vector name can now be configured. This is useful if somebody - wants to use a different hardware interrupt than INT0. - -* Release 2007-08-07 - - - Moved handleIn3 routine in usbdrvasm16.S so that relative jump range is - not exceeded. - - More config options: USB_RX_USER_HOOK(), USB_INITIAL_DATATOKEN, - USB_COUNT_SOF - - USB_INTR_PENDING can now be a memory address, not just I/O - -* Release 2007-09-19 - - - Split out common parts of assembler modules into separate include file - - Made endpoint numbers configurable so that given interface definitions - can be matched. See USB_CFG_EP3_NUMBER in usbconfig-prototype.h. - - Store endpoint number for interrupt/bulk-out so that usbFunctionWriteOut() - can handle any number of endpoints. - - Define usbDeviceConnect() and usbDeviceDisconnect() even if no - USB_CFG_PULLUP_IOPORTNAME is defined. Directly set D+ and D- to 0 in this - case. - -* Release 2007-12-01 - - - Optimize usbDeviceConnect() and usbDeviceDisconnect() for less code size - when USB_CFG_PULLUP_IOPORTNAME is not defined. - -* Release 2007-12-13 - - - Renamed all include-only assembler modules from *.S to *.inc so that - people don't add them to their project sources. - - Distribute leap bits in tx loop more evenly for 16 MHz module. - - Use "macro" and "endm" instead of ".macro" and ".endm" for IAR - - Avoid compiler warnings for constant expr range by casting some values in - USB descriptors. - -* Release 2008-01-21 - - - Fixed bug in 15 and 16 MHz module where the new address set with - SET_ADDRESS was already accepted at the next NAK or ACK we send, not at - the next data packet we send. This caused problems when the host polled - too fast. Thanks to Alexander Neumann for his help and patience debugging - this issue! - -* Release 2008-02-05 - - - Fixed bug in 16.5 MHz module where a register was used in the interrupt - handler before it was pushed. This bug was introduced with version - 2007-09-19 when common parts were moved to a separate file. - - Optimized CRC routine (thanks to Reimar Doeffinger). - -* Release 2008-02-16 - - - Removed outdated IAR compatibility stuff (code sections). - - Added hook macros for USB_RESET_HOOK() and USB_SET_ADDRESS_HOOK(). - - Added optional routine usbMeasureFrameLength() for calibration of the - internal RC oscillator. - -* Release 2008-02-28 - - - USB_INITIAL_DATATOKEN defaults to USBPID_DATA1 now, which means that we - start with sending USBPID_DATA0. - - Changed defaults in usbconfig-prototype.h - - Added free USB VID/PID pair for MIDI class devices - - Restructured AVR-USB as separate package, not part of PowerSwitch any more. - -* Release 2008-04-18 - - - Restructured usbdrv.c so that it is easier to read and understand. - - Better code optimization with gcc 4. - - If a second interrupt in endpoint is enabled, also add it to config - descriptor. - - Added config option for long transfers (above 254 bytes), see - USB_CFG_LONG_TRANSFERS in usbconfig.h. - - Added 20 MHz module contributed by Jeroen Benschop. - -* Release 2008-05-13 - - - Fixed bug in libs-host/hiddata.c function usbhidGetReport(): length - was not incremented, pointer to length was incremented instead. - - Added code to command line tool(s) which claims an interface. This code - is disabled by default, but may be necessary on newer Linux kernels. - - Added usbconfig.h option "USB_CFG_CHECK_DATA_TOGGLING". - - New header "usbportability.h" prepares ports to other development - environments. - - Long transfers (above 254 bytes) did not work when usbFunctionRead() was - used to supply the data. Fixed this bug. [Thanks to Alexander Neumann!] - - In hiddata.c (example code for sending/receiving data over HID), use - USB_RECIP_DEVICE instead of USB_RECIP_INTERFACE for control transfers so - that we need not claim the interface. - - in usbPoll() loop 20 times polling for RESET state instead of 10 times. - This accounts for the higher clock rates we now support. - - Added a module for 12.8 MHz RC oscillator with PLL in receiver loop. - - Added hook to SOF code so that oscillator can be tuned to USB frame clock. - - Added timeout to waitForJ loop. Helps preventing unexpected hangs. - - Added example code for oscillator tuning to libs-device (thanks to - Henrik Haftmann for the idea to this routine). - - Implemented option USB_CFG_SUPPRESS_INTR_CODE. - -* Release 2008-10-22 - - - Fixed libs-device/osctune.h: OSCCAL is memory address on ATMega88 and - similar, not offset of 0x20 needs to be added. - - Allow distribution under GPLv3 for those who have to link against other - code distributed under GPLv3. - -* Release 2008-11-26 - - - Removed libusb-win32 dependency for hid-data example in Makefile.windows. - It was never required and confused many people. - - Added extern uchar usbRxToken to usbdrv.h. - - Integrated a module with CRC checks at 18 MHz by Lukas Schrittwieser. - -* Release 2009-03-23 - - - Hid-mouse example used settings from hid-data example, fixed that. - - Renamed project to V-USB due to a trademark issue with Atmel(r). - - Changed CommercialLicense.txt and USBID-License.txt to make the - background of USB ID registration clearer. - -* Release 2009-04-15 - - - Changed CommercialLicense.txt to reflect the new range of PIDs from - Jason Kotzin. - - Removed USBID-License.txt in favor of USB-IDs-for-free.txt and - USB-ID-FAQ.txt - - Fixed a bug in the 12.8 MHz module: End Of Packet decection was made in - the center between bit 0 and 1 of each byte. This is where the data lines - are expected to change and the sampled data may therefore be nonsense. - We therefore check EOP ONLY if bits 0 AND 1 have both been read as 0 on D-. - - Fixed a bitstuffing problem in the 16 MHz module: If bit 6 was stuffed, - the unstuffing code in the receiver routine was 1 cycle too long. If - multiple bytes had the unstuffing in bit 6, the error summed up until the - receiver was out of sync. - - Included option for faster CRC routine. - Thanks to Slawomir Fras (BoskiDialer) for this code! - - Updated bits in Configuration Descriptor's bmAttributes according to - USB 1.1 (in particular bit 7, it is a must-be-set bit now). - -* Release 2009-08-22 - - - Moved first DBG1() after odDebugInit() in all examples. - - Use vector INT0_vect instead of SIG_INTERRUPT0 if defined. This makes - V-USB compatible with the new "p" suffix devices (e.g. ATMega328p). - - USB_CFG_CLOCK_KHZ setting is now required in usbconfig.h (no default any - more). - - New option USB_CFG_DRIVER_FLASH_PAGE allows boot loaders on devices with - more than 64 kB flash. - - Built-in configuration descriptor allows custom definition for second - endpoint now. - -* Release 2010-07-15 |
