FREERTOS FOR EMBEDDED SYSTEMS: REAL-TIME PROGRAMMING WITH STM32 AND ARM MICROCONTROLLERS: Task Scheduling, Memory Management, and IoT Application Development

Build clearer, safer, and more reliable STM32 firmware with FreeRTOS. Real-time embedded projects become difficult when sensor sampling, interrupts, DMA, UART traffic, logging, memory limits, MQTT connectivity, and fault recovery all compete for attention. This book shows how to organize that complexity with practical FreeRTOS design patterns for STM32 and ARM Cortex-M microcontrollers. Written for embedded developers who want more than surface-level task examples, this guide explains how FreeRTOS works with Cortex-M exceptions, NVIC priorities, STM32Cube projects, queues, semaphores, task notifications, event groups, timers, DMA, memory management, debugging, low-power behavior, and connected IoT firmware. Understand when to use FreeRTOS instead of bare-metal superloop firmware Work with Cortex-M execution, SysTick, PendSV, SVC, context switching, and interrupt priorities Create and organize STM32 FreeRTOS projects with maintainable configuration choices Design tasks, priorities, delays, blocking behavior, and periodic execution correctly Use queues, semaphores, mutexes, event groups, software timers, and direct-to-task notifications Handle UART, ADC, GPIO, EXTI, DMA, and FromISR communication without overloading interrupts Manage stack, heap, static allocation, dynamic allocation, heap_1, heap_4, and heap_5 Detect stack overflow, heap exhaustion, fragmentation, task health problems, and queue backpressure Apply tracing, debugging hooks, tickless idle, watchdog supervision, fault recovery, and safe restart paths Build IoT-ready firmware with MQTT telemetry, cloud commands, JSON payloads, TLS readiness, secure credential concepts, OTA update planning, and reconnect logic Bring the concepts together in a connected STM32 FreeRTOS sensor node architecture This is a code-heavy guide with practical C snippets, configuration patterns, task structures, ISR-safe examples, queue-based workflows, DMA event handling, MQTT task design, and final project architecture patterns that can be adapted to real STM32 development. By the end, you will understand how to design FreeRTOS firmware that keeps time-sensitive work responsive, separates local control from network delays, exposes runtime problems, and prepares embedded applications for more realistic production conditions.
