Previous declaration of 'void TIM2_IRQHandler()' with 'C++' linkage / Interrupt ISR Based Timer

Hey @gruvin - this works now! In order to get this to compile, you need to add it to a library file; it can’t be part of your main .ino file. Then you need to #include "application.h" in that file. If you do that, it should compile as expected!
