Hi,
I have to control 16 pin output pins based on the 16 pin interrupt.
Is it possible to have 16 pins interrupt in nrf52840 . Pin change interrupt
when i config
void statuspinenable() { uint32_t err_code; nrf_drv_gpiote_init(); nrf_drv_gpiote_in_config_t config = { .sense = NRF_GPIOTE_POLARITY_TOGGLE, .pull = NRF_GPIO_PIN_PULLUP, .is_watcher = false, .hi_accuracy = true, .skip_gpio_setup = false}; nrf_drv_gpiote_in_init(sbut1, &config, int_evt_handler); nrf_drv_gpiote_in_init(sbut2, &config, int_evt_handler); nrf_drv_gpiote_in_init(sbut3, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status1, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status2, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status3, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status4, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status5, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status6, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status7, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status8, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status9, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status10, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status11, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status12, &config, int_evt_handler); nrf_drv_gpiote_in_init(Status13, &config, int_evt_handler); nrf_drv_gpiote_in_event_enable(sbut1, true); nrf_drv_gpiote_in_event_enable(sbut2, true); nrf_drv_gpiote_in_event_enable(sbut3, true); nrf_drv_gpiote_in_event_enable(Status1, true); nrf_drv_gpiote_in_event_enable(Status2, true); nrf_drv_gpiote_in_event_enable(Status3, true); nrf_drv_gpiote_in_event_enable(Status4, true); nrf_drv_gpiote_in_event_enable(Status5, true); nrf_drv_gpiote_in_event_enable(Status6, true); nrf_drv_gpiote_in_event_enable(Status7, true); nrf_drv_gpiote_in_event_enable(Status8, true); nrf_drv_gpiote_in_event_enable(Status9, true); nrf_drv_gpiote_in_event_enable(Status10, true); nrf_drv_gpiote_in_event_enable(Status11, true); nrf_drv_gpiote_in_event_enable(Status12, true); nrf_drv_gpiote_in_event_enable(Status13, true); }
it return me the error as
<info> app_timer: RTC: initialized. <error> app: ERROR 3735928559 [Unknown error code] at D:\nRF5xx\1.SDK_17.0.2\modules\nrfx\drivers\src\nrfx_gpiote.c:609 PC at: 0x00032007 <error> app: End of error report
and i check the 609 line in the nrfx_gpiote.c
marking the line : NRFX_ASSERT(pin_in_use_by_gpiote(pin));
under the function
void nrfx_gpiote_in_event_enable(nrfx_gpiote_pin_t pin, bool int_enable) { NRFX_ASSERT(nrf_gpio_pin_present_check(pin)); NRFX_ASSERT(pin_in_use_by_gpiote(pin)); if (pin_in_use_by_port(pin)) { nrf_gpiote_polarity_t polarity = port_handler_polarity_get(channel_port_get(pin) - GPIOTE_CH_NUM); nrf_gpio_pin_sense_t sense; if (polarity == NRF_GPIOTE_POLARITY_TOGGLE) { /* read current pin state and set for next sense to oposit */ sense = (nrf_gpio_pin_read(pin)) ? NRF_GPIO_PIN_SENSE_LOW : NRF_GPIO_PIN_SENSE_HIGH; } else { sense = (polarity == NRF_GPIOTE_POLARITY_LOTOHI) ? NRF_GPIO_PIN_SENSE_HIGH : NRF_GPIO_PIN_SENSE_LOW; } nrf_gpio_cfg_sense_set(pin, sense); } else if (pin_in_use_by_te(pin)) { int32_t channel = (int32_t)channel_port_get(pin); nrf_gpiote_events_t event = TE_IDX_TO_EVENT_ADDR((uint32_t)channel); nrf_gpiote_event_enable((uint32_t)channel); nrf_gpiote_event_clear(event); if (int_enable) { nrfx_gpiote_evt_handler_t handler = channel_handler_get((uint32_t)channel_port_get(pin)); // Enable the interrupt only if event handler was provided. if (handler) { nrf_gpiote_int_enable(1 << channel); } } } }
When i use breakpoints and check.
after enabling 8 pins then the error is thrown
