【STM32学习】（21）STM32实现步进电机

实物图：

实现示意图：其实看着示意图就可以实现步进电机转动了。

四相五线的步进电机。

4线为：A B C D

该步进电机分为4拍和8拍

4拍：分为单四拍和双四拍

单四拍：A-B-C-D-A-

双四拍：AB-BC-CD-DA-AB-

8拍：

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

想让步进电机反转，只需要将顺序反转就行。

主要代码为：

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 */
		/* 正转  8拍 */

  }
  /* USER CODE END 3 */
}

效果如下：
