I'm using visual studio 2013 and visual micro as add ones for arduino coding. If I run my code in arduino IDE ,code compiles fine but when I compile the same code in visual studio , it says "Unable to resolve library include path 'SPI'"
I include those libraries via visual micro and it shows all of them. So I guess it's not that my library directory is wrong.
How can I solve this problem ? what may be the reason for this? thanks
