Build production-grade IoT firmware using STM32, FreeRTOS, and MQTT with ESP32 as a Wi-Fi coprocessor. Covers task isolation, queue-driven design, UART DMA, reconnection state machines, security, and real production deployment patterns.
Learn how STM32 Sleep, Stop, and Standby modes work — with real HAL code, RTC wakeup design, FreeRTOS Tickless Idle, GPIO leakage fixes, and battery life estimation techniques for professional IoT firmware engineers.
Learn how to get started with Zephyr RTOS on STM32 in this complete 2026 guide — covering setup, Device Tree, Kconfig, BLE development, OTA with MCUboot, power management, and why Zephyr is the most important RTOS skill for embedded engineers today.
Artificial Intelligence is no longer limited to cloud servers, GPUs, or high-performance Linux systems. Modern microcontrollers are now capable of running optimized machine learning inference
Embedded systems have long been the quiet backbone of modern electronics. From industrial controllers and automotive ECUs to consumer electronics and medical devices, microcontrollers and
Introduction In embedded systems, responsiveness and timing precision are often critical. When a hardware event occurs — such as a GPIO edge, UART byte received,
Introduction In many embedded systems, it’s not always possible — or practical — to use interrupts. Some peripherals don’t provide interrupt lines, others generate events
Introduction Mechanical switches, buttons, and some sensors don’t produce clean, instantaneous transitions between ON and OFF states. Instead, they generate a series of rapid, unpredictable
Introduction In many embedded systems, one hardware event or sensor reading must be used by multiple parts of the system. For example: If each module
Introduction Complex embedded systems quickly develop messy interaction graphs: sensors trigger logic that wakes radios, which log to flash, while power management tries to keep
