帮我写一个stm32c8t6上的rtc实时时钟代码

好的，我可以回答这个问题。以下是一个简单的stm32c8t6上的rtc实时时钟代码：

#include "stm32f1xx_hal.h"

RTC_HandleTypeDef hrtc;

void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_RTC_Init(void);

int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_RTC_Init();

while (1)
{
RTC_TimeTypeDef sTime;
RTC_DateTypeDef sDate;

HAL_RTC_GetTime(&hrtc, &sTime, RTC_FORMAT_BIN);
HAL_RTC_GetDate(&hrtc, &sDate, RTC_FORMAT_BIN);

printf("Current Time: %02d:%02d:%02d\r\n", sTime.Hours, sTime.Minutes, sTime.Seconds);
printf("Current Date: %02d-%02d-%02d\r\n", sDate.Date, sDate.Month, 2000 + sDate.Year);

HAL_Delay(1000);
}
}

void SystemClock_Config(void)
{

{
Error_Handler();
}

{

}
}

static void MX_RTC_Init(void)
{

/** Initialize RTC Only

hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN;
if (HAL_RTC_Init(&hrtc) != HAL_OK)
{
Error_Handler();
}

/** Initialize RTC and set the Time and Date
*/
sTime.Hours = 12;
sTime.Minutes = 0;
sTime.Seconds = 0;

if (HAL_RTC_SetTime(&hrtc, &sTime, RTC_FORMAT_BIN) != HAL_OK)
{
Error_Handler();
}

sDate.WeekDay = RTC_WEEKDAY_MONDAY;
sDate.Month = RTC_MONTH_JANUARY;
sDate.Date = 1;
sDate.Year = 0;

if (HAL_RTC_SetDate(&hrtc, &sDate, RTC_FORMAT_BIN) != HAL_OK)
{
Error_Handler();
}
}

static void MX_GPIO_Init(void)
{

__HAL_RCC_GPIOC_CLK_ENABLE();

GPIO_InitStruct.Pin = GPIO_PIN_13;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;

HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);
}

void Error_Handler(void)
{
while (1)
{
}
}

注意：以上代码仅供参考，具体实现需要根据实际情况进行调整。
