RE: How can use Gpiote Interrupt with s110?

Thank you for your advice. I used the "app_button_enable ()" function. Um.. If the setting two buttons, Works well. But When the set of four buttons, Does not operate. I need four button.

Hi, GunMin!

When we call APP_GPIOTE_INIT(APP_GPIOTE_MAX_USERS), the SDK call function: app_gpiote_init in app_gpiote.c and in this function the SDK initialise interrupt for GPIOTE_IRQn.

The interrupt handler "GPIOTE_IRQHandler", defined in same src file (app_gpiote.c), where there is a call the callback-function, defined in struct app_button_cfg_t.

if in app_button_cfg_t you do not define callback (4 parameter for each button), interrupt will not occur.

In example "ble_app_bps" calback is null for button BOND_DELETE_ALL_BUTTON_ID because pressing for this button checked "manualy", through func. "nrf_gpio_pin_read" like this:

nrf_gpio_pin_read(BOND_DELETE_ALL_BUTTON_ID) == 0.

Best regards.
