STM32CubeMX + freeRTOS线程操作（一）

1、说明

在freeRTOS中创建两个任务，当按键第一次被按下后，任务1挂起，当再按下按键后 任务1恢复，

2、添加任务

3、线程1代码实现

/* USER CODE BEGIN Header_LED_Thread1 */
/**
  * @brief  Function implementing the LED1 thread.
  * @param  argument: Not used
  * @retval None
  */
/* USER CODE END Header_LED_Thread1 */
void LED_Thread1(void const * argument)
{
  /* USER CODE BEGIN 5 */
  /* Infinite loop */
	static uint8_t timerCount = 0;
	static uint8_t state = 0;
  for(;;)
  {
   osDelay(10);
	  if( HAL_GPIO_ReadPin(GPIOE,Key1_Pin) == 0 ) {
			timerCount++;
			if(timerCount >=25 ) {
				timerCount = 0;
				state = !state;
			}
		} 
		if( state) {
			osThreadResume(LED2Handle);
		} else {
			osThreadSuspend(LED2Handle);
			HAL_GPIO_WritePin(GPIOF,GPIO_PIN_9,GPIO_PIN_SET);
		}
	}
  /* USER CODE END 5 */
}

4、线程2代码实现

/* USER CODE BEGIN Header_LED2_Thread */
/**
* @brief Function implementing the LED2 thread.
* @param argument: Not used
* @retval None
*/
/* USER CODE END Header_LED2_Thread */
void LED2_Thread(void const * argument)
{
  /* USER CODE BEGIN LED2_Thread */
  /* Infinite loop */
  for(;;)
  {
    osDelay(200);
		 HAL_GPIO_TogglePin(GPIOF,GPIO_PIN_9);
  }
  /* USER CODE END LED2_Thread */
}
