Embedded Systems Programming

FROM ARDUINO TO ADVANCED IOT SOLUTIONS WITH ESP32 AND C++

Have you ever wanted to go beyond simply blinking LEDs and start developing complex, stable, and connected electronic devices? This manual is the definitive guide to transforming your passion for electronics into professional-level embedded programming skills.

Through a progressive and highly practical journey, you will discover how to maximize the power of C++ on widely used hardware platforms such as Arduino and the powerful dual-core ESP32 microcontroller. You will move beyond amateur approaches to embrace advanced techniques: from careful memory and pointer management to Object-Oriented Programming (OOP) optimized for resource-constrained systems.

The book will guide you step-by-step from basic hardware interfacing to the Internet of Things, teaching you how to:

• Master Hardware: Manage I/O, PWM, Interrupts, Timers, and communicate with your sensors via I2C, SPI, and UART protocols.
• Unlock the Power of ESP32: Leverage wireless connectivity by implementing Wi-Fi networks and Bluetooth Low Energy (BLE) devices.
• Develop with Multitasking: Move beyond sequential programming to embrace Real-Time Operating Systems (RTOS), managing parallel tasks with FreeRTOS.
• Build Complete IoT Architectures: Save data locally (EEPROM, SPIFFS/LittleFS) and send it to the cloud using industry-standard protocols such as MQTT and HTTP.
• Create Professional Products: Implement low-power modes for battery-operated devices, master advanced debugging techniques, and apply best practices for security and deployment.

Whether you are an engineering student, an experienced maker looking to level up, or a software developer eager to get your hands dirty with hardware, this text will provide you with the concrete tools needed to design reliable, secure, and scalable embedded systems.
