PlatformIO & VS Code Projects: Build Professional IoT And Embedded Systems With FreeRTOS, ESP32, STM32, And Arduino Using Hands-On Projects

Tired of shallow embedded tutorials that never go beyond blinking LEDs? Most engineers struggle because real firmware work requires more than random snippets. You need a unified workflow that connects PlatformIO, VS Code, FreeRTOS, ESP32, STM32, RP2040, MQTT, BLE, LoRaWAN, OTA updates, secure provisioning, and CI/CD into one disciplined, production-ready system. This book delivers exactly that.

Many developers spend months stitching together blog posts: one guide for ESP32 Wi-Fi, another for STM32 HAL, another for GitHub Actions, but none for manufacturing tests, fleet maintenance, SBOM checks, rollback protection, or certificate provisioning. The result is fragile firmware that works only on your desk but fails in the field.

This book teaches you how to build real production-style PlatformIO projects end-to-end. You will learn reproducible workspace structures, multi-environment platformio.ini patterns, correct FreeRTOS task design, device-to-cloud pipelines using MQTT and REST, resilient reconnect logic, deterministic builds, hardware-in-the-loop testing, secure OTA pipelines with rollback, pinned TLS backends, secrets at rest, and the manufacturing processes needed to ship reliable devices at scale.

➡️ That’s why I wrote “PlatformIO & VS Code Projects: Build Professional IoT And Embedded Systems With FreeRTOS, ESP32, STM32, And Arduino Using Hands-On Projects” — a practical field manual for turning raw microcontroller boards into stable, tested, monitored, and maintainable embedded products. This book goes far beyond PlatformIO basics; it gives you the engineering patterns real teams use.

Inside, you will learn how to:

• Structure professional PlatformIO + VS Code workspaces with multi-env builds, custom flags, debugging probes, and automated tests.

• Design FreeRTOS task graphs, queues, memory-safe timers, and logging systems for scalable sensor, MQTT, and telemetry workloads.

• Implement Wi-Fi resilience, backoff, NVS/flash config, MQTT QoS, retained messages, offline buffering, and telemetry hardening.

• Build PIO/DMA pipelines on RP2040, USB/UF2 tooling, and VS Code capture workflows for reproducible logic analysis.

• Deploy low-power LoRa/LoRaWAN field nodes with sleep modes, payload compression, duty cycling, and field-diagnostic routines.

• Create secure OTA pipelines with signed images, anti-rollback layouts, staged/canary rollouts, SBOM generation, and CI/CD release gates.

• Provision devices with unique keys, certificates, hardened TLS, pinned CAs, and rotation-aware secrets at rest.

• Build manufacturing test flows, fixtures, golden images, calibration checks, RMA diagnostics, safe wipes, fleet metrics, and SLAs.

Ideal for embedded developers, IoT engineers, and serious builders who want structured, reproducible firmware workflows rather than disconnected experiments, this book provides deterministic commands, clear folder patterns, and real projects that scale across boards and environments.

If you want PlatformIO and VS Code to become your complete firmware engineering environment — covering ESP32, STM32, RP2040, FreeRTOS, MQTT, BLE, LoRaWAN, OTA, provisioning, manufacturing, and CI/CD — this book is your roadmap.
