stm32ds1302实时时钟

对于stm32ds1302实时时钟，您可以使用STM32 HAL库提供的DS1302驱动程序来进行控制。以下是使用HAL库的示例代码：

#include "stm32f1xx_hal.h"
#include "ds1302.h"

DS1302_HandleTypeDef hds1302;

int main(void)
{
  /* 初始化HAL库 */
  HAL_Init();

  /* 初始化DS1302 */
  hds1302.Pin_CE = GPIO_PIN_0;
  hds1302.Pin_IO = GPIO_PIN_1;
  hds1302.Pin_SCLK = GPIO_PIN_2;
  hds1302.Instance = GPIOA;  hds1302.Mode = DS1302_MODE_READWRITE;
  hds1302.Pull = GPIO_NOPULL;
  hds1302.Speed = GPIO_SPEED_FREQ_HIGH;
  DS1302_Init(&hds1302);

  /* 设置时间 */
  DS1302_SetTime(&hds1302, 2021, 7, 1, 12, 30, 0);

  /* 循环读取时间并显示 */
  while (1)
  {
    DS1302_Time time;
    DS1302_GetTime(&hds1302, &time);
    printf("%04d-%02d-%02d %02d:%02d:%02d\n", time.year, time.month, time.day, time.hour, time.minute, time.second);
    HAL_Delay(1000);
  }
}
