【STM32】FreeRTOS开启后,不再进入主函数的while(1)
开启freertos后,想在主函数的while(1)中实现led的翻转,发现无法实现。
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();
MX_USART1_UART_Init();
/* USER CODE BEGIN 2 */
/* USER CODE END 2 */
/* Call init function for freertos objects (in freertos.c) */
MX_FREERTOS_Init();
/* Start scheduler */
osKernelStart();
/* We should never get here as control is now taken by the scheduler */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
HAL_GPIO_TogglePin(GPIOF,GPIO_PIN_9);
HAL_Delay(1000);
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}
分析原因:
osKernelStart();
/* We should never get here as control is now taken by the scheduler */
osKernelStart();
语句后面有一个注释:
/* We should never get here as control is now taken by the scheduler */
我们永远不会到达这里,因为控制权现在被调度器拿走了
