<div class='showpostmsg'>## 5: FreeRTOS application### 5.1: CubeMX configuration Open the existing project and find the relevant configuration of FreeRTOS, as follows:  The current configuration is gray. You need to download the corresponding resource package to facilitate the corresponding source code and install it.  After the installation is complete, there will be the corresponding freertos configuration.  After the installation is complete, configure:  Then configure RTOS  ### 5.2: Create tasks We create 2 tasks, one task LED flashes, and one task serial port prints data once per second; LED blinking task: ``` void StartDefaultTask1(void *argument) { /* USER CODE BEGIN defaultTask */ /* Infinite loop */ for(;;) { HAL_GPIO_TogglePin(GPIOA,GPIO_PIN_5); vTaskDelay(500); } /* USER CODE END defaultTask */ } ``` Serial port printing task: ``` void StartDefaultTask2(void *argument) { /* USER CODE BEGIN defaultTask */ /* Infinite loop */ for(;;) { printf("1000ms\r\n"); vTaskDelay(1000); } /* USER CODE END defaultTask */ } ``` In the “MX_FREERTOS_Init” function, initialize and create these two tasks: ``` xTaskCreate( StartDefaultTask2, // Function pointer, Task function "printf_task", // Task name 200, // Stack size, in word, 10 means 40 bytes NULL, // Parameter osPriorityNormal passed in when calling the task function, // Priority NULL); // Task handle, use it to operate this task in the future xTaskCreate( StartDefaultTask1, // Function pointer, Task function "led_task", // Task name 200, // Stack size, in word, 10 means 40 bytes NULL, // Parameter osPriorityNormal passed in when calling the task function, // Priority NULL); // Task handle, use it to operate this task in the future ``` 5.3: Implementation results You can check whether your task is executed according to the serial port output; </div><script> var loginstr = '<div class="locked">To view all the contents of the post, please <a href="/bbs/member.php?mod=logging&action=login" style="color:#e60000" class="loginf">log in</a> or <a href="/bbs/member.php?mod=register_eeworld.php&action=wechat" style="color:#e60000" target="_blank">register</a></div>'; if(parseInt(discuz_uid)==0){ } </script><script type="text/javascript">(function(d,c){var a=d.createElement("script"),m=d.getElementsByTagName("script")[0],eewurl="//counter.eeworld.com.cn/pv/count/";a.src=eewurl+c;m.parentNode.insertBefore(a,m)})(document,523)</script>
