【iCore1S 双核心板_ARM】例程十三：SDIO实验——读取SD卡信息

实验现象：

核心代码：

int main(void)

  /* USER CODE BEGIN 1 */
    HAL_SD_TransferStateTypedef State;

  /* USER CODE END 1 */

  /* MCU Configuration----------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* Configure the system clock */
  SystemClock_Config();

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_SDIO_SD_Init();
  MX_USART1_UART_Init();
  SystemClock_Config();

  /* USER CODE BEGIN 2 */
