I am using Visual Studio 2013 to write code for AVR. I have been following this tutorial.
Whilst writing the code, I noticed that Visual Studio kept on underlining things like DDRB
or PORTB
and I keep on getting errors like Error: identifier "PORTB" is undefined
, however, the program compiles correctly.
Interestingly enough, upon pressing alt-F12 Visual finds numerous files where they are defined.
