TwinAVR 1.1.0.4 (old name: WinAVR) by Roland Walter

- LowCost programmer for all known AVR microcontrollers.
- Very simple handling, optimized for very comfortable handling.
- "No click" operation whith files given by command line.
- SP12 or Kanda Dongle compatible low cost hardware at LPT port.
- Runs under Windows 3.x/9x/ME and Win-OS/2. For NT3/NT4/Win2000/XP
  a port driver is needed, see below.
- Able to copy Calibration Bytes into EEPROM.

NT notes:
Unter NT systems (NT 3.51, NT 4, Win2000, XP) You need to install
the driver userport.sys which enables direct hardware (port) access.
The driver userport.sys does this job fine for NT3/NT4/Win200/XP.
Other known drivers:
- The driver totalio.sys works under NT3/4 and 2000 *without* servicepack only.
- Under Win2000 I got success with the driver PortTalk 2.2. But PortTalk is
  less handy then userport.sys
- For Windows 3.x, 9x, ME and Win-OS/2 there is *no* special driver needed.

History:

New in WinAVR 1.0
- Works under NT systems with userport.sys driver now.
- Support for ATtiny2313, ATmega48, ATmega88, ATmega168
- Reading out Flash/EEPROM reported "Locked in mode 3" since I had
  changed Lock/Fuse bits to the original negative logic (sorry for this)
- Now You can close all dialog windows simply and fast with ESC key
- Messageboxes now only after errors (wished by many users)
- Selection of LPT1/LPT2/LPT3 improved, in some systems incorrect LPT
  names where displayed (a problem because WinAVR must bypass Windows)

New in WinAVR 1.0.0.2
- Due to a Windows 98 bug, programming with WinAVR 1.0 wasn't possible
  under this Windows version. Erasing and setting Fuses/Lock bits was OK.
  Other Windows versions: No problems

New in TwinAVR 1.0 (= WinAVR 1.1.0.0)
- Support for Atmel AVR ISP dongle ("Kanda dongle")

New in TwinAVR 1.0.0.1
- Bugfix: Flash was erased when burning EEPROM only
- TwinAVR quits automaticly now if Flash/EEPROM file loaded from command line
- Update feb. 2004: driver userport.sys included instead of totalio.sys 
- Update march 2004: Circuit for the Kanda compatible dongle corrected

New in TwinAVR 1.0.1.0
- Support for ATmega165
- Now last used filename is stored in ini file and used as default for
  file selection box.

New in TwinAVR 1.0.2.0
- New AVRs: AT90CAN128, ATmega3290, ATmega325, ATmega645, ATmega649,
  ATmega2560 and ATmega2561.
- Bugfix: ATmega64 Fuse Bits corrected
- Bugfix: ATtiny2313 correctly recognized now
- Bugfix: Filenames with starting and ending Double-quot ("") not found
  when lading from command line
- Safe speed enhancement for Flash writing of newer AVRs which support page
  writing.
- Minor bugfix: Alt+F4 works now under all circumstances. It's however more simple to
  quit TwinAVR using the ESC key.

New in Version 1.1.0.0:
- Important bugfix: Since one of the several Win2k/XP updates long filenames for
  16 bit programs are not longer supported. Therefore TwinAVR wasn't able to
  open/create ("find") files with names longer then 8+3 with a lot of Win2000/XP
  systems. Windows 9x/ME was *not* affeced by this problem.

New in Version 1.1.0.1:
- Confused version numbers in version 1.1.0.0: One in window title, next in EXE
  resource, other in help ;-)
- Now You can use the Alt+Space key shortcut to open the system menu of the main window
- Bug (Windows 3.x only): Canceling file selection wasn't possible
- Bug (Windows 3.x only): When read-out the AVR creation of new file failed. Only
  overwriting existing worked.

New in Version 1.1.0.2:
- ATtiny25, ATtiny45 and ATtiny85 added.

New in Version 1.1.0.3:
- Support for ATtiny261, ATtiny461, ATtiny861, ATtiny24, ATtiny44, ATtiny84

New in Version 1.1.0.4:
- Support for ATmega164P, ATmega324P, ATmega644P, ATmega644
