并行构建项目能够减小构建时间。(stm32cubeIDE默认并行编译)

2_手册翻译

3.1_PWM呼吸灯

PWM 的周期就是 16MHz/(15+1)/(99+1) = 10kHz

int main(void)
{
  /* USER CODE BEGIN 1 */
uint16_t pwm_val=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_TIM1_Init();
  /* USER CODE BEGIN 2 */
HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1);//使能PWM
  /* USER CODE END 2 */

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

    /* USER CODE BEGIN 3 */
	  while(pwm_val<50){
		 pwm_val++;
		 __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_1,pwm_val); //设置占空比
		 HAL_Delay(50);
	  }
	  
	  while(pwm_val){
			 pwm_val--;
			 __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_1,pwm_val);
			 HAL_Delay(50);
		  }
	  
  }
  /* USER CODE END 3 */
}
