Hello STM Community,
I am currently working with the STM32C031C6 Nucleo board to implement various power reduction techniques, including Sleep, Stop, and Standby modes. At this stage, I am trying to wake the MCU from STOP mode using the RTC wakeup timer without relying on any external triggers such as the user button.
While several working examples and tutorials exist for other STM32 families like STM32L4 and STM32F4, I have found that those approaches do not directly apply or work as expected on the STM32C031C6.
If anyone has successfully implemented RTC wakeup from STOP mode on this MCU, I would greatly appreciate any guidance, insights, or a minimal working example to help move forward.
Thank you in advance for your support!
