Blinking LEDs - setting board in Keil

[Gavin]

I'm struggling to get started using Keil with an NRF51822 mounted on a custom board that I have cobbled together.

I have opened the blinky/pca10031 example as a starting point because I would like to similarly test the indicator LEDs on my board, but my LEDs are connected to different pins, so I will need to use a custom_board.h file to define the LED pin numbers. The problem is, I don't understand how to tell Keil to include the custom_board.h file, rather than the pca10031.h file.

I can see that the pca10031.h file is included because BOARD_PCA10031 has been defined, but cannot find where this has been done.

Apologies if this is a dumb question - forgive me, I'm new to developing with nrf/Keil.

Thanks in advance for any advice

BOARD_PCA10031 is defined as a Preprocessor Symbol and can be edited by going to the C/C++ tab of the 'Options for Target' dialog.(Right click on the Target in the Project window.)

At first you have to build your project. If the project is build with success, right click on LED and select: Go to Definition of "name of your LED". Then you will get the pca10031.h file. In this file you can simply change the pins of the LEDs.
