A practical guide to MQTT protocol for embedded systems and IoT. Learn how MQTT works, QoS levels, retained messages, libraries in C/Python/JavaScript/Go, and real-world use cases with code examples.
Practical comparison of ESP32 (Xtensa dual-core MCU with integrated Wi-Fi/BLE) vs ARM Cortex-A application processors for IoT projects. Learn cost, power, complexity tradeoffs, and when each is the right choice for your connected device.
A practical guide to retrieving hardware specifications on Linux and embedded systems: CPU info, RAM, storage, peripherals, network interfaces, kernel details, and embedded-specific hardware data.
A practical guide to polling vs interrupt-driven programming in embedded systems. Learn when to use each approach, trade-offs, platform examples (Arduino, ARM, Linux), and real-world code patterns.
A practical engineer's guide to designing safe OTA firmware update systems for embedded devices. Learn about bootloaders, A/B partitions, signature verification, rollback mechanisms, and how to prevent bricking devices during updates.
A practical engineer's guide to selecting the right microcontroller for embedded projects. Learn what factors matter most: performance, peripherals, power consumption, tooling, availability, cost, and long-term support.
A practical guide for embedded engineers on generating audio and voice using PWM. Learn why PWM frequency matters, how PWM acts as a low-cost DAC, the role of Nyquist theorem, filtering requirements, and real-world implementation on STM32, ESP32, and Arduino.
A short practical NMEA 0183 guide with sentence structure, checksum verification, common message types, and full parsing examples for real projects.
Learn receiver blocking in practical RF terms: why it matters, how tests are run, how PER is used, and how it differs from sensitivity and adjacent channel rejection.
A practical engineer-focused guide to embedded storage technologies including NAND, NOR, QSPI flash, eMMC, SD card, ROM, RAM, EEPROM, and FRAM, with pros and cons, common use cases, and selection advice for real products.
