Introduction to FreeRTOS Interrupts The highest interrupt priority that can call interrupt-safe FreeRTOS API functions is determined by the interrupt service routine. Do not call interrupt-safe FreeRTOS API functions from any interrupt with a higher priority than this (the higher the priority, the lower the numerical value). The code is as follows (version FreeRTOS V202107.00): … Read more

Experimental conditions: Basic knowledge of C language, with an integrated development environment such as Keil uVision5. Design Experiment In this experiment, we will continue to … Read more
FreeRTOS is a small, portable, open-source real-time operating system kernel, commonly used in embedded systems. Due to its lightweight design, it is very suitable for resource-constrained devices, such as microcontrollers. Here are some key features of FreeRTOS: Real-time Task Scheduling: Provides multiple task scheduling strategies to ensure that real-time tasks can be executed on time. … 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
