No i dont put my c# code inside Arduino :))
But C# is easy to translate (although be it a bit more work..); i first do c# for faster development, later it might become c++
I understand its a lot for arduino perspective, but compared to my labtop its almost nothing (12Gig mem)
And wel 32MB isnt realy huge, for exampl a memory stick on my desk is 4GB and the other stick is 64GB...
But i can imagine that wouldnt be addressable with arduino so much, just 32B or so would allready be fine.
