Tasks and Task ManagementThe fundamental building block of FreeRTOS is the Task. You can think of a task as a small, self-contained program that runs in an infinite loop.

void vLED2_Task(void *pv) while(1) HAL_GPIO_TogglePin(LED2_GPIO_Port, LED2_Pin); vTaskDelay(pdMS_TO_TICKS(1000)); freertos tutorial pdf

To prevent a task from hogging the CPU, use vTaskDelay . This moves the task from "Running" to "Blocked" for a specified number of "ticks." Tasks and Task ManagementThe fundamental building block of

Modern embedded systems require more than simple super-loops. Tasks with varying deadlines, responsiveness, and power constraints demand a Real-Time Operating System (RTOS). FreeRTOS stands out due to its open-source nature, portability (over 40 architectures), and small memory footprint (as low as 4-10 KB ROM). This tutorial paper synthesizes the core components found in official FreeRTOS documentation and community PDFs into a coherent learning path. This moves the task from "Running" to "Blocked"

FreeRTOS is a market-leading real-time operating system (RTOS) designed for microcontrollers. It is small, simple, and widely used across industries ranging from consumer electronics to industrial automation. Distributed under the MIT license.

This is why you use an RTOS. Standard Linux or Windows cannot guarantee timing. FreeRTOS can.
