Add one new button failed in pca10056.h

[wyzl2000]

in pca10056.h, there are 4 buttons.

I want to add one new button, //#define BUTTON_5       NRF_GPIO_PIN_MAP(1,06).

However , it failed.

I debug and find the issue, #define BUTTONS_NUMBER 4, the BUTTONS_NUMBER can not be set as 5 or more.

If the BUTTONS_NUMBER is 4 or 3, it is OK.

Why?

How can I add one new button, thanks!

How do you come to that conclusion?

Hi !

I debug,and find buttons_leds_init------bsp_init-------app_button_init-------nrfx_gpiote_in_init，

in nrfx_gpiote_in_init，err_code = NRFX_ERROR_NO_MEM.

Try setting GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS in sdk_config.h to 5
