What function should be used to associate an interrupt with an event?

[RJD]

I wanted to know the function or functions and the steps to associate an interrupt with an event.

I will be getting a single Pulse(Low To High) which will be my interrupt signal.

I wanted to read this and generate an event to sleep.

Can someone please let me know the step by step function's usage?

I wanted something similar to the  bsp_event_to_button_action_assign(BTN_ID_RESET,BSP_BUTTON_ACTION_RELEASE,BSP_EVENT_RESET);

from pwr_mgmt example, but to read from a high pulse.

Hi,

 

Check out the pin change example in the nRF5 SDK: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/pin_change_int_example.html?cp=7_1_4_6_20

 

Best regards,

Andreas

Hello Andreas, Thank you for your reply.

could you please explain me the function line by line or step by step in the code snippet.

I did go through the links- 

a.) https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v13.0.0%2Fgroup__nrf__drv__gpiote.html

b.) https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Fgroup__nrf__drv__gpiote.html

c.) https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.3.0%2Fgroup__nrf__drv__gpiote.html&anchor=ga00970227fc2c393fbbc71b3d362b58c2

But I didnt understand anything properly. 

Also, I wanted to know how to generate an event and associate it with the pins as I didnt understand anything.

I would like to request you to kindly please not provide links with just 1 line explanations, but brief explanations as my knowledge is less. If required kindly please also provide links to tutorials or explanations needed to be read beforehand.

I apologize if I am sounding rude, it was not the intention, but to give you a better idea in order to assist me. 

Also how does this line work- nrf_drv_gpiote_in_init(PIN_IN, &in_config, in_pin_handler); ?  Please explain in brief

As in_pin_handler is a function and also not of type  nrfx_gpiote_evt_handler_t   but void ? Please explain in brief

And also why does nrf_drv_gpiote_in_init does throw an error when in_pin_handler is called on being of a void type and not nrfx_gpiote_evt_handler_t .?  Please explain in brief

Q2- How are the parameters being passed to in_pin_handler in nrf_drv_gpiote_in_init?  Please explain in brief

Q3- How and where are the "action" parameter being generated  and passed? Please explain in brief.

Q4- Also how to associate the action(function name(s) too) with an event to put the device to sleep or any other event I want to use it for? Please explain in brief.

 

tatic void gpio_init(void)
{
    ret_code_t err_code;

    err_code = nrf_drv_gpiote_init();
    APP_ERROR_CHECK(err_code);

    nrf_drv_gpiote_out_config_t out_config = GPIOTE_CONFIG_OUT_SIMPLE(false);

    err_code = nrf_drv_gpiote_out_init(PIN_OUT, &out_config);
    APP_ERROR_CHECK(err_code);

    nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(true);
    in_config.pull = NRF_GPIO_PIN_PULLDOWN;

    err_code = nrf_drv_gpiote_in_init(PIN_IN, &in_config, in_pin_handler);
    APP_ERROR_CHECK(err_code);

    nrf_drv_gpiote_in_event_enable(PIN_IN, true);
}

Also, my input is a single pulse of Low To High To low of 50 ms.

I want to read that , generate an event , pass that event to put the device to sleep

Hello ANdreas, there is another thing, I want to combine this code https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v17.0.2%2Fpin_change_int_example.html&cp=7_1_4_6_20

and this https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v17.0.2%2Fpin_change_int_example.html&cp=7_1_4_6_20

Basically I want to generate an event using the interrupt to put the device to sleep- or lets say a counterpart to bsp_event_to_button_action_assign(BTN_ID_RESET,BSP_BUTTON_ACTION_RELEASE,BSP_EVENT_RESET); this function.
