DA14531 DeepSleep

Question

I am using DA14531MOD with SDK6 
 
 I am writing a program to make the microcomputer sleep with reference to this Website. 
 11. スリープモード &mdash; DA145XX チュートリアル SDK はじめに 
 
 This Website uses extended sleep on the microcomputer, but how can I use deep sleep?

Hi Yoshihiko, 
 Thank you for posting your questions online. 
 You can refer to this tutorial for applying the deep sleep: 
 DA1453x & DA1458x Sleep Modes Tutorial &mdash; DA1453x & DA1458x Tutorial Sleep Modes 
 Any further questions are welcome.

HI Yoshihiko, Thank you for the reply. Please refer on our prox_reporter where the Deep Sleep mode is implemented. You can have the 3 RAM blocks retained during Deep Sleep. After waking-up you should start from the RTC callback. Inside the RTC callback you should re-initialize the BLE core and the peripheral blocks. After the initialization you can continue executing the code. Instead of declaring the user_app_adv_restart as the RTC callback, declare another callabck as shown in prox_reporter example.

Hi Yoshihiko, Thank you for the reply. Please refer on the arch_set_deep_sleep API: /**
 ****************************************************************************************
 * @brief Activates deep sleep mode.
 * @param[in] ram1 Selects the RAM1 state (on/off) during the hibernation.
 * @param[in] ram2 Selects the RAM2 state (on/off) during the hibernation.
 * @param[in] ram3 Selects the RAM3 state (on/off) during the hibernation.
 * @param[in] pad_latch_en true = Enable latching of pads state during sleep,
 * false = Disable latching of pads state during sleep.
 * @details The system can wake-up from the following sources:
 * - POR (power on reset)
 * - GPIO(s) using the wake-up controller
 * - Interrupt generated by the RTC
 * - Interrupt generated by the Timer1
 *
 * @note The wake-up condition must be configured prior to putting the system in
 * deep sleep.
 * If RTC and Timer1 are not going to be used as wake-up sources, it is
 * recommended to close the PD_TIM prior to putting the system in deep sleep.
 * The exit from the deep sleep state causes a system reboot.

void arch_set_deep_sleep(pd_sys_down_ram_t ram1,
 pd_sys_down_ram_t ram2,
 pd_sys_down_ram_t ram3,
 bool pad_latch_en); Please try to call the API while the pad_latch_en parameter is set to true to keep the state of the GPIOs and there is no reason to re-configure the Peripheral blocks. Best Regards, OV_Renesas
