Notes
the single greatest number of “bug” reports we get are due to the user not setting the env variable AVR.
on a linux system:
export AVR=/usr/local/avr (or wherever you've installed it, $HOME/avr, /opt/avr, etc ) export AVRROOT=$AVR export AVRBIN=$AVRROOT/bin export AVRLIB=$AVRROOT/lib/avrlib export PATH=$AVR/bin:$PATH
these can be placed in your ~/.bashrc file
of course, the $AVRROOT should be where the user has placed the toolchain and avrlib ( /opt/avr and ~/avr are popular too )
there is a generated rc file in the root of the install dir as well, it can be modified to suit.
From avr-as –help
AVR options:
-mmcu=[avr-name] select microcontroller variant
[avr-name] can be:
avr1 - AT90S1200, ATtiny1x, ATtiny28
avr2 - AT90S2xxx, AT90S4xxx, AT90S8xxx, ATtiny22
avr3 - ATmega103, ATmega603
avr4 - ATmega83, ATmega85
avr5 - ATmega161, ATmega163, ATmega32, AT94K
or immediate microcontroller name.
-mall-opcodes accept all AVR opcodes, even if not supported by MCU
-mno-skip-bug disable warnings for skipping two-word instructions
(default for avr4, avr5)
-mno-wrap reject rjmp/rcall instructions with 8K wrap-around
(default for avr3, avr5)

Basic “getting started” needs
- a few AVRs
- a compiler/linker
- a mechanism to upload/download to/from the microcontroller
- breadboard
- a power supply
- various components ( LEDs, resisters for said, ect )
