how to generate sdk_config.h when using eclipse?

[victor]

Do I need to manually go though every HW exaple in the examples in sdk12 and cut and paste all the little bits that I need or is there any other way? I have a custom board with many of the peripheral enabled.

You can use the open source Java tool CMSIS Configuration Wizard to set configurations in the sdk_config.h file. I recommend that you use the config file found in examples\ble_peripheral\ble_app_template\ as a starting point, as this contains most of the defines.
