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).
