ANCS example with different board

[ancassidy]

Im using a board that is not one of the officially supported nRF51822 boards. Im trying to get the ANCS example project to work, but It wont broadcast or even turn on the LEDs. I created a new header file for the board and added it to boards.h, and again, nothing. Am I defining the board wrong? is there an ANCS example that doesnt rely on BSP?

Hey. Does your board have a 32Khz crystal? If not, the code will be stuck at:

SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL);

As for the BSP, you can feel free to remove all references to it. Alternatively, you can do:

#define BSP_DEFINES_ONLY
#define BSP_SIMPLE

Then bsp will be inactive.

Ah, looks like my board does not, only a 16Mhz crystal. How do I use the synthesized 32khz clock source instead?

Use NRF_CLOCK_LFCLKSRC_RC_250_PPM_TEMP_4000MS_CALIBRATION instead of NRF_CLOCK_LFCLKSRC_XTAL_20_PPM in the SOFTDEVICE_HANDLER_INIT call.
