gpiote problem

[bean]

platform :  nrf 52832     SDK : 14.0.0

I used gpiote to detect sensor's interruption  . there  are  two  sensors ,so  I configure the gpiote like this :

void platform_gpio_int_initialize()
{
    if (!nrf_drv_gpiote_is_init())
    {
    nrf_drv_gpiote_init();
    } 
    
    nrf_gpio_cfg_input(LIS_3DH_INT1_PIN, NRF_GPIO_PIN_NOPULL);
    nrf_gpio_cfg_input(LIS_6DS_INT1_PIN, NRF_GPIO_PIN_NOPULL);
    
    nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_HITOLO(false);
    
    in_config.pull = NRF_GPIO_PIN_PULLUP;
    
    
    nrf_drv_gpiote_in_init(LIS_6DS_INT1_PIN, &in_config, lis_6ds_interrup_handle);
    nrf_drv_gpiote_in_init(LIS_3DH_INT1_PIN, &in_config, lis_3dh_interrup_handle);
    
    nrf_drv_gpiote_in_event_enable(LIS_6DS_INT1_PIN, true);
    nrf_drv_gpiote_in_event_enable(LIS_3DH_INT1_PIN, true); 

}

neither of the two sensors' interruption couldn't be detected  ...

I tried to modify code :

1. I  deleted  "nrf_drv_gpiote_in_event_enable(LIS_6DS_INT1_PIN, true);"  the other sensor's interruption  could be  detected .

2. "GPIOTE_CONFIG_IN_SENSE_HITOLO(false);"   I used  'true' to replace 'false',  the two sensors' interruption could be detected .

-----------------------

according to this link : https://devzone.nordicsemi.com/f/nordic-q-a/8071/nrf_drv_gpiote_in_event_enable-function-doesn-t-re-enable-event     I found that  there's a bug in GPIOTE. 

so I want to know if the bug has been fixed already .

Hi,

Recommend to check the return values from the function calls, there may be an error during initialization of the in events.

Have you set  GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS to > 2 in sdk_config.h?

hi,

   Thank you for  helping me with my question !

     I have checked the return values . all of the return values are 0.   I also checked the GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS ,  it's  4  in sdk_config.h.

    I also wanna know the difference between 'GPIOTE_CONFIG_IN_SENSE_HITOLO(false);' and  'GPIOTE_CONFIG_IN_SENSE_HITOLO(true );'.  because the problem would be solved  if I use 'GPIOTE_CONFIG_IN_SENSE_HITOLO(true )' to replace 'GPIOTE_CONFIG_IN_SENSE_HITOLO(false )' .
