Various fixes and improvements (#96)

* Global variables shared between an interrupt and the main code should be volatile

See: https://www.embedded.com/electronics-blogs/beginner-s-corner/4023801/Introduction-to-the-Volatile-Keyword

* There is no reason to change the active report if it has not changed

* Declare local functions and variables static

This both helps the compiler and the programmer
