The datasheet is available here and webhelp is hereĪny comments, reviews, criticicm and feedback will be appreciated and considered. Some limitations which are mainly due to the effort required are no pointers, windows only, and some issues with custom libraries. Most features have been added as user requests but as the simulator has become more mature with less crashes, there has been much less feedback.
Simulator for Arduino can simulate most parts of an Arduino sketch including classes, objects, interrupts, multi-line expressions and multi-expression lines with debugging features such as breakpoints, single step debugging, external stimulus files, trace, graphical logic analyzing, variable watching and many more features. So far, the Simulator has over 50k users logged (note some of these may be duplicates) with just under 10k of these taking up the Pro option. There is an option to use a standard to stay anonymous but the email address is used mainly for update notifications. This is a free download from here and gives a 30 minute trial and then 30 days after following an unlock process using an email address to prevent spammers. The latest version of Simulator for Arduino v1.04B has just been released.
