Hey,
When I call fn nrf_drv_gpiote_in_event_enable, the event handler is immediately called. Note that at the beginning of the fn I even read the pin to verify it's high. I also know it's high because I'm scoping it. Also, this code does work properly when the line transitions to low.
Is there a way to stop this erroneous event from happening when enabled???
ret_code_t err_code;
nrf_gpio_cfg_input(gp_board_config->irq, NRF_GPIO_PIN_PULLUP);
{
volatile uint32_t read = nrf_gpio_pin_read(gp_board_config->irq);
// Setting break point here verifies this line is high.
read++;
}
err_code = nrf_drv_gpiote_init();
APP_ERROR_CHECK(err_code);
/**
* Sam will set the interrupt aka wakeup line low until nrf responds with Ack.
*/
nrf_drv_gpiote_in_config_t irq_config = NRFX_GPIOTE_CONFIG_IN_SENSE_HITOLO(false);
err_code = nrf_drv_gpiote_in_init(gp_board_config->irq, &irq_config, m_gpiote_evt_handler);
APP_ERROR_CHECK(err_code);
CRITICAL_REGION_ENTER();
nrf_drv_gpiote_in_event_enable(gp_board_config->irq, true);
{
nrf_gpiote_events_t event = nrfx_gpiote_in_event_addr_get(gp_board_config->irq);
nrf_gpiote_event_clear(event);
NVIC_ClearPendingIRQ(GPIOTE_IRQn);
}
CRITICAL_REGION_EXIT();
Note I even tried disabling ints, and then clearing the event and the interrupt - no success.
