I have installed Keil v5.18a and have installed MDK for nRF51-DK.
Examining the basic LED blink examples showed that in some projects, the 'bsp.h' which would be the header file for 'bsp.c' is shown and in some other projects it is not available.
1st image: a screenshot of a project that allows to view 'bsp.h'
2nd image: a screenshot of a project that DOES NOT allow me to view 'bsp.h'
What determines this difference? I'd like to be able to see the 'bsp.h' file in my project buy I have no clue what to configure in order to do so.
