实验5：开放性实验内容：按键B1调节电机转速，按下按键速度递增，速度达到设定的最大值后，再按键速度递减，速度达到设定的最小值后，再按键速度递增。同时通过软件STMStudio软件查看设定的速度变量。

一、软件程序
重新设置PC13端口为输入

程序代码：
int main(void)
{
  /* USER CODE BEGIN 1 */
  uint16_t speedcnt=0;
  uint8_t  speedup=1;
  uint8_t  speeddown=0;
  /* 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();
  MX_ADC1_Init();
  MX_DAC_Init();
  MX_TIM1_Init();
  MX_USART2_UART_Init();
  MX_MotorControl_Init();

  /* Initialize interrupts */
  MX_NVIC_Init();
  /* USER CODE BEGIN 2 */

  MC_StartMotor1();
  HAL_Delay(1000);
  MC_ProgramSpeedRampMotor1(2000/6,1000);
  HAL_Delay(10000);

  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {

if(GPIO_PIN_RESET == HAL_GPIO_ReadPin(GPIOC,GPIO_PIN_13))
{
   HAL_Delay(10);
   if(GPIO_PIN_RESET == HAL_GPIO_ReadPin(GPIOC,GPIO_PIN_13))
   {
      if(speedup==1)
      {
      speedcnt=speedcnt+100;
      if(speedcnt>14000)
      {
         speedup=0;
         speeddown=1;
      }
      }
      if(speeddown==1)
      {
      speedcnt=speedcnt-100;
      if(speedcnt<200)
      {
         speedup=1;
         speeddown=0;
      }
      }
      MC_ProgramSpeedRampMotor1((2000+speedcnt)/6,1000);
   }
}
HAL_Delay(100);

  /* USER CODE END WHILE */

  /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */

}

二、执行结果：
