STM32 HAL库中有没有RTC_SetCounter函数 [复制链接]

我在STM32的HAL库中找了好长时间的RTC_SetCounter函数，也没有找到。这个函数是不是操作32位秒累加寄存器的。

用HAL如何操作RTC_CNTL,RTC_CNTH这两个寄存器。

rtc .Instance-> 结构里是寄存器，不知道你32什么型号和cube版本

RTC_TypeDef *Instance; /*!< Register base address */

STM32L431 HAL CUBE 5.4.0版本。在“stm32l431xx.h”文件中没有发现 RTC_CNTL和RTC_CNTH两个寄存器。

那应该是没有，你再兑一下手册，这个型号我没用过

谢谢，我看了STM32F407和STM32G431的寄存器定义都没有。不知道是为什么呀。我是用串口配置时钟，但是只知道从2000年到现在时间的秒数，不想自己计算时间和日期了。
