1、新建工程
2、配置工程
在这里插入图片描述

3、启动STM32CUBEMX
（1）配置RCC
在这里插入图片描述

（2）配置SDMMC1

4、SD卡初始化

int sdcard_status = 0;
HAL_SD_CardCIDTypedef sdcard_cid;
MX_SDMMC1_SD_Init();
fre = HAL_RCC_GetSysClockFreq();
printf("%d\r\n",fre);
fre = HAL_RCC_GetHCLKFreq();
printf("HCLKFreq = %d\r\n",fre);
fre = HAL_RCC_GetPCLK1Freq();
printf("PCLK1Freq = %d\r\n",fre);
fre = HAL_RCC_GetPCLK2Freq();
printf("PCLK2Freq = %d\r\n",fre);


sdcard_status = HAL_SD_GetCardState(&hsd1);
if(sdcard_status == HAL_SD_CARD_TRANSFER)
{
		printf("SD card init ok!\r\n\r\n");
		
		//打印SD卡基本信息
		printf("SD card information!\r\n");
		printf("CardCapacity: %llu\r\n",((unsigned long long)hsd1.SdCard.BlockSize*hsd1.SdCard.BlockNbr));
		printf("CardBlockSize: %d \r\n",hsd1.SdCard.BlockSize);
		printf("RCA: %d \r\n",hsd1.SdCard.RelCardAdd);
		printf("CardType: %d \r\n",hsd1.SdCard.CardType);
		
		//读取并打印SD卡的CID信息
		HAL_SD_GetCardCID(&hsd1,&sdcard_cid);
		printf("ManufacturerID: %d \r\n",sdcard_cid.ManufacturerID);
}
else
{ 
		printf("SD card init fail!\r\n" );
}
