【STM32學習】（21）STM32實現步進電機

實物圖：

實現示意圖：其實看著示意圖就可以實現步進電機轉動了。

四相五線的步進電機。

4線為：A B C D

該步進電機分為4拍和8拍

4拍：分為單四拍和雙四拍

單四拍：A-B-C-D-A-

雙四拍：AB-BC-CD-DA-AB-

8拍：

A-AB-B-BC-C-CD-D-DA-A-

想讓步進電機反轉，只需要將順序反轉就行。

主要代碼為：

int main(void)
{
  /* USER CODE BEGIN 1 */
  /* USER CODE END 1 */
  /* MCU Configuration--------------------------------------------------------*/
  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();
  /* USER CODE BEGIN Init */
  /* USER CODE END Init */
  /* Configure the system clock */
  SystemClock_Config();
  /* USER CODE BEGIN SysInit */
  /* USER CODE END SysInit */
  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  /* USER CODE BEGIN 2 */
  /* USER CODE END 2 */
  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
    /* USER CODE END WHILE */
    /* USER CODE BEGIN 3 */
		/* 正轉  8拍 */

  }
  /* USER CODE END 3 */
}

效果如下：
