How to undefined LEDs and Buttons in custom code?

[Ankush]

Hi,

In my application, using BMD301 i have made one custom PCB. I am using SDK 12.0.0. In my PCB I have not used all the four LEDs. I have assigned p0.19 to the BSP_LED_0 which is required for advertising indication. all the Other BSP_LEDs i am not using . but the pins assigned to these on eval kit are used for different application. Does it make any difference?

Also I am getting some issues when i am using p0.20 for difference purpose on eval kit? D o we need to comment the definition of corresponding LEDs in pca10040. or is there any other method available apart from this.

In my custom PCB board I have assignes P0.20 as SPI clk for ADXL 362 acceleromter.

  #define ADXL_SCK              20
  #define ADXL_MOSI             0
  #define ADXL_MISO             1
  #define ADXL_CS               18

But proper configuration is not happening. Same thing I tried on eval kit and I faced same issue. Then simply changed ADXL_SCK to 3 then SPI configurations worked fine.

What is the issue with p0.20.?
