How to use USB to wake up in hibernation mode

Hello, DA team

How to use USB to wake up in hibernation mode？

I check the documentation, wkup can only be configured through gpio and can not use other peripherals？

--------------------------------------------------------------------

Table 234: Register map WakeUp

WKUP_SELECT_P0_REG.....

WKUP_POL_P0_REG......

WKUP_STATUS_0_REG.........

WKUP_SEL_GPIO_P0_REG................

----------------------------------------------------------------------

但在

-----------------------------------------------------

Table 8: Power modes and configurations

Analog blocks

LDO_USB=OPT
LDO_RET= ON
LDO_VBAT=OFF
LDO_IO=OPT
BandGap=OFF
LDO_CORE=OFF
SIMO=OPT
LDO_RAD= OPT
LDO_VBAT_RET=OPT
LDO_VBUS_RET=OFF
LDO_IO_RETx=OPT
LDO_SLEEP=OFF

--------------------------------------------------------

But the API of the SDK can only be configured as follows：

---------------------------------------------------

hw_wkup_init(NULL);
hw_wkup_set_debounce_time(32);
hw_wkup_configure_pin(HW_GPIO_PORT_2, HW_GPIO_PIN_2, true,HW_WKUP_PIN_STATE_HIGH);
hw_wkup_register_interrupt(wkup_handler, configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY);

-------------------------------------------------------

How to configure LDO_USB ？

Hi There,

Hi There,

In DA14682/3 products you are not able to wake up from hibernation via USB. You can only wake up from the wake-up controller. However, the hibernation is a shipping mode and it is recommended only for the final product, not for development scopes.

Thanks, PM_Dialog

I use the pm_mode_extended

I use the pm_mode_extended_sleep mode to measure power consumption of 0.2ma.Is it wrong with me?

If I want very low power (like shutdown) but can wake up via USB, how do I set it up?

thanks

Hi There,

Hi There,

In case of extended sleep mode, DA14682 can wake-up in two ways:

  • Synchronously, from the Timer1 or the BLE timer in Extended Sleep mode only.
  • Asynchronously, from the Wake-up timer or the VBUS (USB) interrupt.

In case of hibernation mode, DA14682 can only wake-up asynchronously from the Wake-up timer.

Thanks, PM_Dialog
