Got my Arduboy and have been playing with it, cool little device!
I hacked together a thing that let’s me use my comfortable Visual C++ 2005 IDE for running/debugging Arduboy stuff, presenting it here in case anybody wanted to try it or see the code.
It’s not an emulator, it just fakes the Arduboy 1.1 and 1.2 API well enough to compile and run Arduboy source code. It lacks audio (well, it can do a half hearted attempt at tone(), that’s about it) & eeprom support, and probably a lot more stuff.
A vine movie of it in action can be seen here.
Supports html5 compiles, try in your browser here.
Why do I still use MSVC++ 2005? Because I’m old and like the IDE better than the 2015 version, despite also using that for some of my other stuff.
