avr编译环境 ICCAVR6.30 破解版本

for details.


Current bug lists. They will be fixed ASAP.
- Debug generation does not work for filenames longer than 13 characters.
- If you have an expression of the form
	char column;

	if ((column << column) == 0 || column == 3)
		...
  
  bad code is generated
- If you have an interrupt handler and if the previous function's last 
  instruction is a NOP, then the COFF file does not contain correct interrupt
  entry for the handler. e.g.

  void foo() { asm("nop"); }
  #pragma interrupt_handler timer:4
  void timer() { ...

  causes the interrupt entry for timer not to be generated correctly under
  COFF (hex file is OK)

CHANGE LOG:
7/28/02 - V6.11A
  ADDed osccal.zip in \icc\examples.tiny. This contains AppNote 012 from AVR 
  Freaks on how to write the Calibration Byte to the OSCCAL register and a
  sample project

  IDE
    - Added NextErr/FirstErr
    - Improved FindInFiles
  Compiler
    - the compiler was generating cli/sei pair to protect R30 (SP) 
      modification even inside an interrupt handler (e.g. to do lpm flash
      constant access). This causes interrupts to be enabled inside the
      handler which can cause problems.

02/11/02 - V6.11
  ADDed support for OPTIONAL hardware dongle
  IDE
    - Add ISP support
  Compiler
    - fixed: if you reduce the stack size, the compiler starts to release
      R0 and up for local use. However, in the interrupt handler code, it
      still used R0 for saving and restoring the SREG.
  Header files
    - macros.h incorrectly #define'd flash to be const.
    - iotiny*v.h added. These header files should be used instead of the
      older iotiny*.h (without the ending 'v') since they define the
      registers more consistently and they define the interrupt vectors. 
    - assembly header files aiotiny*.s added. For documentation, see
      \icc\include\tiny_c_lst and \icc\include\tiny_asm_lst for info on
      these new header files

07/16/01 - V6.10b
  IDE
    - Added new Project Tree
    - The target device selection now allows you to select specific device
      with the max. number of interrupt vector entry.
    - You can now add a command to run after a successful build
      Project->Options->Compiler
    - Allow COFF/HEX to be selected as the output format, allowing both
      COFF output for debugging and Intel HEX for ISP programming.
  Header files
    - fixed header file problems in iotiny12.h and iotiny15.h

04/10/01 - V6.10a
  Better Licensing dialog boxes. Mostly important for new users.

03/27/01 - V6.10
  IDE
  	- NEW! Application Builder wizard for generating peripheral 
      initialization code!
	- You can now use UltraEdit32 (purchased separately :-) ), TextPad, or
	  WinEdit "integrated"
	  with the IDE. You can select different editors in
	  Tools->EnvOptions->General->Editors. Future releases may include more
	  editors and even tighter integration.
  C Preprocessor
  	- Russian characters were causing the preprocessor to hang
	- Added vararg #define when -e flag is on:
		#define db(a, ...)	printf(a, __VA_ARGS__)
	  allows db() to be called with one or more arguments
	- now accepts binary constant (0b....) if the 
	  Project->Options->Compiler->AcceptExtension checkbox is on
  Include Files
  	- added iotiny10.h and fixed INT0 and INT1 in iotiny28.h

01/29/01 - V6.00C
  - Added *.src to the \icc\examples.tiny directory
  Linker
  	- the linker was generating HEX files with lower case HEX numbers and
	  some programmer software do not handle them correctly

10/06/00 - V6.00B
  io1200.h was the wrong version
  clarify the t0_int.h regarding interrupt # usage

06.01/00 - V6.00A
  IDE/Driver/library
  	- now accepts vector from 0-9 to support Tiny15
  Header File
  	- now includes io1200.h

02/09/00 - V6.00
	Initial Release

	CHANGES SINCE SOME EARLIER BETAS to improve compatibility with ICCAVR:
	- interrupt handler now use 
		#pragma interrupt_handler <func>:<vec>
	  format, note that it takes a vector number and not a word
	  address as before
	- inline asm is now specified using asm() instead of _asm()
	- variable references within inline asm now uses % key instead
	  of $
