- ******************************************************************************
- * @file stm32f0xx_hal_timebase_rtc_wakeup_template.c
- * @brief HAL time base based on the hardware RTC_WAKEUP Template.
- *
- * This file overrides the native HAL time base functions (defined as weak)
- * to use the RTC WAKEUP for the time base generation:
- * + Intializes the RTC peripheral and configures the wakeup timer to be
- * incremented each 1ms
- * + The wakeup feature is configured to assert an interrupt each 1ms
- * + HAL_IncTick is called inside the HAL_RTCEx_WakeUpTimerEventCallback
- * + HSE (default), LSE or LSI can be selected as RTC clock source

- ##### How to use this driver #####
- ==============================================================================
- [..]
- This file must be copied to the application folder and modified as follows:
- (#) Rename it to 'stm32f0xx_hal_timebase_rtc_wakeup.c'
- (#) Add this file and the RTC HAL drivers to your project and uncomment
- HAL_RTC_MODULE_ENABLED define in stm32f0xx_hal_conf.h
-
- [..]
- (@) HAL RTC alarm and HAL RTC wakeup drivers can’t be used with low power modes:
- The wake up capability of the RTC may be intrusive in case of prior low power mode
- configuration requiring different wake up sources.
- Application/Example behavior is no more guaranteed
- (@) The stm32f0xx_hal_timebase_tim use is recommended for the Applications/Examples
- requiring low power modes
