RTC时钟频率 = RTC时钟源 / ((Asynchronous Predivider value + 1) * (Synchronous Predivider value + 1))= 1Hz,也就是1秒 之后到时钟配置里面可以看到已经使能了 初始化 static void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ /* USER CODE BEGI...
Here is my code (simplified, I only let the RTC Init part and System Clock configuration): #include "main.h" RTC_HandleTypeDef rtcHandle; RTC_InitTypeDef rtcInit; RTC_TimeTypeDef rtcTime; RTC_DateTypeDef rtcDate; static void SystemClock_Config(void); static void Error_Handler(void); int ma...
可接3V电池,系统断电时为芯片内部的RTC和备用寄存器提供电源。 引脚2:I/O口/入侵检测IRTC。I/O口输出或读取高低电平;入侵检测提供安全保障,可以将外部一些防拆的触点接在此端口,若触点电平变化,STM32芯片会自动清空寄存器数据:RTC可输出RTC校准时钟、RTC闹钟脉冲、秒脉冲。 引脚3、4:I/O口/32.765kHzRTC晶振 ...
在rtc的相关的功能代码中,添加以下代码段:/* USER CODE BEGIN 0 */ _calendar_obj calendar; // ...
This function configures the hardware resources used in this example 代码语言:javascript 复制 voidHAL_RTC_MspInit(RTC_HandleTypeDef*hrtc){RCC_PeriphCLKInitTypeDef PeriphClkInitStruct={0};if(hrtc->Instance==RTC){/* USER CODE BEGIN RTC_MspInit 0 *//* USER CODE END RTC_MspInit 0 *//** Init...
}/* USER CODE BEGIN RTC_Init 2 *//* USER CODE END RTC_Init 2 */} 可以看到outline里面有很多我们需要的函数,那么自己扩展就可以使用了 This function configures the hardware resources used in this example 登录后复制voidHAL_RTC_MspInit(RTC_HandleTypeDef* hrtc) ...
