How to use bsp_event_to_button_action_assign function to assign long push action to an event?

Hi Everyone

I have been trying to do some simple led blinking by generating events , however i need to do that if a button_0 is pressed for some duration.

Here is a code that i have been trying to use without any success.

Thanks 

Rajat!

  • Hi!

    Did you make any progress on your issue?

    You could simply add a new event to the bsp_event_t enum in the bsp.h file.

    ie. BSP_EVENT_LONG_TEST

    and change your code to;

    void bsp_evt_handler(bsp_event_t evt)
    {
    
        uint32_t err_code;    
        switch (evt)
        {
            case BSP_EVENT_LONG_TEST:
                  
                  nrf_gpio_pin_toggle(13);
                  
                  break;
            case BSP_EVENT_KEY_1:
                 
                  nrf_gpio_pin_toggle(14);
                  break;
             case BSP_EVENT_KEY_2:
                  
                  nrf_gpio_pin_toggle(15);
                  break;
            case BSP_EVENT_KEY_3:
                
                  nrf_gpio_pin_toggle(16);
                  break;
                   
            default:
                return; // no implementation needed
        }
       
    }

    and;

    int main(void)
    {
        bool pressed;
        clock_initialization();
      
        uint32_t err_code = app_timer_init();
        APP_ERROR_CHECK(err_code);
        
        
        
        bsp_event_to_button_action_assign(BUTTON_1,BTN_ACTION_LONG,  BSP_EVENT_LONG_TEST);
        bsp_configuration();
    }

    This should make your defined button output only the "LONG PRESSED".

    Let me know if you have further questions.

    Best regards,
    Joakim.
