问 Announcing WinAVR 20030115

WinAVR (pronounced "whenever") is a suite of executable, open source
software development tools for the Atmel AVR series of RISC
microprocessors hosted on the Windows platform. It includes the
GNU GCC compiler.

WinAVR CAN be found at http://sourceforge.net/projects/winAVR/


Below is just a sample of what's new.

- Corrected sample makefile.

- Added to the sample makefile automatic C file dependency
generation.

- Added more documentation: binutils, make, as (GNU assembler),
  ld (GNU linker), and GCC. Now there's no excuse not to RTFM!

- Refactored the utilities. Added bash.

- Added editor: Programmer's Notepad 2. This is in early stages and
will develop into an IDE in the near future. This editor includes the
Scintilla editor component.

- Note that GNU GCC 3.3 is no longer labeled experimental and is now
labeled as prerelease. The tentative release date for GCC 3.3 is mid-
February 2003.

- This version of WinAVR includes GNU Binutils 2.13.2.1 which is the
latest released version. Previous versions of WinAVR included
Binutils 2.14 experimental versions.
  
- AVRLibC now includes an experimental sCANf library thanks to J鰎g
Wunsch.
  
- AVRLibC has completely new rewrites of the trigonometrical
functions asin(), atan() and atan2() that feature a better (for some
argument ranges even much better) accuracy than the previous
versions. Note that since acos() uses asin(), it also benefits from
this. These were contributed by Reiner Patommel.

- Two example projects with source code are included. These are from
AVRLibC. Look under <InstallDir>\doc\examples. These examples also
include different kinds of makefiles than in the sample directory.


For more information see the README.txt file that comes in the binary
installation.

答 1: 多谢hudaidai 答 2: WinAVR 的makefile 做得不好我得把makefile模板重写。

你可以增加几个target，如：
dump:
<tab> AVR-objdump -S -h $(TARGRT).elf >dump.txt
<tab> notepad dump.txt

install :
<tab> 根据你的下载器指定uisp 参数，可以并口STK 200 dongle、串口AVRisp等,甚至可以是Altera ByteBlaste 下载电缆。

这样,编译完以后
make install 直接下载代码到AVR。
make dump  反汇编原代码到dumop.txt，并自动用记事本打开。
