With the next configuration, the INT1 don't start.

Base on (

)

lsm303agr_xl_operating_mode_set(&dev_ctx_xl, LSM303AGR_XL_POWER_DOWN);

lsm303agr_int1_src_a_t int_source_get;

lsm303agr_xl_int1_gen_source_get(&dev_ctx_xl, &

int_source_get

);

lsm303agr_xl_data_rate_set(&dev_ctx_xl, LSM303AGR_XL_ODR_50Hz);

WhoamI return correct value.

I work with a NRF52,

For read the pin i

nterrupt

:

ret_code_t err_code;

err_code = nrf_drv_gpiote_init();

APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_HITOLO(false);

in_config.pull = NRF_GPIO_PIN_PULLUP;

err_code = nrf_drv_gpiote_in_init(INT_1, &in_config, in_pin_handler);

APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_event_enable(

INT_1

, true);

The 'in_pin_handler' never called.
