Hi HiberXen

You can read more about the Board Support Package (BSP) here, or in the BSP tutorial, here.

It is possible to use it with a custom board. You can copy one of the existing board files (e.g pca10040.h), rename it to custom_boards.h and the modify it to your requirements (change pin config. etc). After you have created your custom board file, you have to modify the boards.h file to include the file you created.

Like this:

..
#elif defined(BOARD_CUSTOM)
   #include "custom_board.h"
..

Then, in Keil, go to options for target -> C/C++ tab -> Define -> Remove the board_pca10040 and add your BOARD_CUSTOM.

As for blinking the LED, I would recommend that you take a look at this tutorial, which sets up a timer that toggles an LED.

Best regards
