Important note for Arduino users
 
 

Many OshonSoft.com software users reported that OshonSoft.com AVR Simulator IDE could be successfully used with Arduino systems.
 
Here is the comment I got from Mr. Rubens Luciano:
 
I want to mention that it's possible and easy to upload hex files produced with the AVR Simulator IDE basic compiler to Arduino systems using the original Arduino bootloader and a free program like 'Xloader' (there are others, too).
