of microcontrollers of ATMEL,
with many extended and new features. Works on Win64 and Linux(i386) command
lines. The advantages of gavrasm:
gavrasm is also available in a graphical version. This version is built in in the
AVR simulator avr_sim.

My AVR-Assembler is available in an english, french, german and turkish version and can
easily be translated to other languages (send me your edited gavrlang_xx.pas and the
ReadMe.Txt file for further translation to other languages). An experimental Chinese
version is available at
Github. See the
German page for the German version.
View the ReadMe.Txt for more informations on features.
See also the introduction to the use and some notes on special
features of gavrasm.
The english version of 4.1 for Linux-64-Bit was unfortunately compiled with the
German language file. This error is now corrected.
