二、STM32F103基于RTC实现简单日历
1、RTC
实时时钟芯片是日常生活中应用最为广泛的消费类电子产品之一。它为人们提供精确的实时时间,或者为电子系统提供精确的时间基准,目前实时时钟芯片大多采用精度较高的晶体振荡器作为时钟源。有些时钟芯片为了在主电源掉电时，还可以工作，需要外加电池供电。

2、CubeMX创建项目
先设置引脚如图
RTC
RCC
USART1
时钟
3、代码
main.c外
#include <stdio.h>
int fputc(int ch,FILE *f)
{
HAL_UART_Transmit(&huart1,(uint8_t *)&ch,1,0xFFFF);
//μè′y·￠?í?áê?
while(__HAL_UART_GET_FLAG(&huart1,UART_FLAG_TC)!=SET){
}
return ch;
}
RTC_DateTypeDef date; //??è?è??ú?á11ì?
RTC_TimeTypeDef time; //??è?ê±???á11ì?
main.c中
date.Year=21;
date.Month=12;
date.Date=4;
date.WeekDay=RTC_WEEKDAY_FRIDAY;
time.Hours=23;
time.Minutes=19;
time.Seconds=20;
HAL_RTC_SetDate(&hrtc,&date,RTC_FORMAT_BIN);
HAL_RTC_SetTime(&hrtc,&time,RTC_FORMAT_BIN);
while (1)
{
/* USER CODE END WHILE */
HAL_RTC_GetTime(&hrtc, &time, RTC_FORMAT_BIN);
HAL_RTC_GetDate(&hrtc, &date, RTC_FORMAT_BIN);
printf("%0004d/%02d/%02d %02d:%02d:%02d\r\n",date.Year+2000,date.Month,date.Date,time.Hours,time.Minutes,time.Seconds);
HAL_Delay(1000);
