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.
Clear explanation of MCU, CPU, and MPU: what they are, key differences, and practical examples from real systems.
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 practical engineer-friendly guide to CPU and MCU performance metrics in embedded systems. Learn what MHz, MIPS, DMIPS, CoreMark, CoreMark/MHz, and FLOPS really mean, when they help, when they mislead, and how to select the right processor for real workloads.
