Explanation:1. In general applications, we usually set the task RTOS system clock tick (heartbeat) to 1ms, but if we directly set the RTOS system clock tick to 1us, the system burden is very high, and many RTOS cannot switch tasks every 1us at a 100MHz main frequency, resulting in the RTOS not having time to … Read more
Recently, a friend and I discussed some strange aspects of the FreeRTOS code generated by STM32CubeMX. void LED01Tog(void const * argument){ /* USER CODE BEGIN LED01Tog */ /* Infinite loop */ for(;;) { HAL_GPIO_TogglePin(GPIOF,GPIO_PIN_10); osDelay(500); } /* USER CODE END LED01Tog */} We added two LED toggle functions, compiled our code, and found that the … Read more
1. Uses of FreeRTOS FreeRTOS is generally used in hardware designs where there are certain limitations on RAM size (cost, resources, performance-to-power ratio, etc.). It is one of the most widely used real-time operating systems today. Choosing FreeRTOS for project applications generally considers the following aspects: Real-time (time constraints): Like most RTOS, at each clock … Read more
