WebbHow to use RTC periodic wakeup (from standby) on STM32L0 I am trying to periodically wakeup STM32L010K8 from standby mode. The project is generated is using CubeMX. The device doesn't wakeup unless I reinitialize RTC everytime it resumes from standby. How can I avoid reinitialization of RTC everytime? /* USER CODE BEGIN Header */ /** Webb29 sep. 2024 · Standby mode if the RTC clock is provided by LSE or LSI; Shutdown mode if the RTC clock is provided by LSE(b) Since you are using the LSI, the lowest power mode achievable for your RTC peripheral is the Standby mode. The shutdown mode is reached when you power off your system (even if you have VBAT connected), which is your case.

WebbI'm experimenting with standby mode on STM32F4O7VGT6. I know how to put MCU into standby mode(or I think to know that). I'm doing that with this init function: void MX_RTC_Init(void) { Webb21 mars 2024 · CM4 wakes up and puts D3 and then D2 in standby mode. CM7 configures RTC and enables EXTI_LINE19 for D1 and D2.

timer - STM32 wake up from standby by RTC - Stack Overflow
WebbI have a problem with RTC wake up. I use LSE 32.768kHz. I run example from manufacturer to wake up MCU from Stand by mode very 1min, 2mins. Everything work okay. But, When I put delay 10s and HAL_PWR_EnterSTANDBYMode (); into while (1). Everything is not okay. Webb12 mars 2014 · You can wake up the CPU with RTC clocked by LSI. LSI can run in stand-by mode if you configure it to do so, and as long as Vdd is powered. the manual says: 40 kHz low speed internal RC (LSI RC) which drives the independent watchdog and optionally the RTC used for Auto-wakeup from Stop/Standby mode. Expand Post.
