SDK:17.1.0
application: ble_app_uart(+ble_app_buttonless dfu service)
bootloader:secure bootloader pca10040e_s112_ble
Background:
There is only one key(pin:31) on the PCBA board, through which you can enter the DFU and wake up from power off mode to enter the main application.
Content of application:
One button,six LEDs.
app_pwm(TIMER1)1.timeout of 1ms 2.calculate the key input time
drv_pwm:Realize pwm output of LED
When the key starts, you can change the light mode by pressing the button.
But mainloop and app_timeout_handler do not run when the key is pressed and not released. Only when the key is released will the program work properly. When I was debugging, I found that after pressing a key, the port_event_handler kept getting stuck.static void port_event_handle(uint32_t * latch)
{
do {
for (uint32_t i = 0; i < NRFX_GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS; i++)
{
if (m_cb.port_handlers_pins[i] == PIN_NOT_USED)
{
continue;
}
/* Process pin further only if LATCH bit associated with this pin was set. */
nrfx_gpiote_pin_t pin = port_handler_pin_get(i);
if (nrf_bitmask_bit_is_set(pin, latch))
{
nrf_gpiote_polarity_t polarity = port_handler_polarity_get(i);
nrf_gpio_pin_sense_t sense = nrf_gpio_pin_sense_get(pin);
NRFX_LOG_DEBUG("PORT event for pin: %d, polarity: %d.", pin, polarity);
/* Reconfigure sense to the opposite level, so the internal PINx.DETECT signal
* can be deasserted. Therefore PORT event generated again,
* unless some other PINx.DETECT signal is still active. */
nrf_gpio_pin_sense_t next_sense =
(sense == NRF_GPIO_PIN_SENSE_HIGH) ? NRF_GPIO_PIN_SENSE_LOW :
NRF_GPIO_PIN_SENSE_HIGH;
nrf_gpio_cfg_sense_set(pin, next_sense);
/* Try to clear LATCH bit corresponding to currently processed pin.
* This may not succeed if the pin's state changed during the interrupt processing
* and now it matches the new sense configuration. In such case,
* the pin will be processed again in another iteration of the outer loop. */
nrf_gpio_pin_latch_clear(pin);
/* Invoke user handler only if the sensed pin level
* matches its polarity configuration. */
nrfx_gpiote_evt_handler_t handler =
channel_handler_get((uint32_t)channel_port_get(pin));
if (handler &&
((polarity == NRF_GPIOTE_POLARITY_TOGGLE) ||
(sense == NRF_GPIO_PIN_SENSE_HIGH && polarity == NRF_GPIOTE_POLARITY_LOTOHI) ||
(sense == NRF_GPIO_PIN_SENSE_LOW && polarity == NRF_GPIOTE_POLARITY_HITOLO)))
{
handler(pin, polarity);
}
}
}
} while (latch_pending_read_and_check(latch));
}
I think this is usually caused by nrf_delay_ms, but I didn't use it in the code. Timing is achieved by app_pwm.
Hopefully I've made it clear enough that you can read it. I don't quite understand this phenomenon. Could you give me some ideas to solve the problem?5554.sdk_config.h
