Embedded Systems & Electronics Engineering
Practical embedded systems and electronics articles on firmware, C and C++, device drivers, PCB design, debugging, Linux tools, and measurement systems.
Building a Raspberry Pi controlled sine wave generator with AD9850 and AD9851 modules, practical wiring notes, CLI and text user interface control, simulation checks, and scope-verified output.
A practical guide to the Linux skills embedded and firmware engineers should prioritize for building, flashing, debugging, serial I/O, automation, and real hardware bring-up.
A comprehensive embedded guide to bit masks, register fields, target intrinsics, packed protocol values, atomicity, and C++ std::bitset.
Datasheet-to-driver patterns for SPI ADCs, sensors, DACs, and other peripheral chips, covering timing rules, transaction shape, testing, and board bring-up.
What std::span fixes about pointer-plus-length APIs, where it fits in firmware and tools, and which lifetime, bounds, DMA, and toolchain issues it still cannot protect.
How to build maintainable I2C chip drivers for sensors, ADCs, EEPROMs, GPIO expanders, and other peripheral devices without leaking bus details into application code.
A practical debugging workflow for C and C++ firmware, drivers, Linux utilities, and test tools: capture failures, replay inputs, instrument boundaries, protect timing, and verify fixes.
How to structure Qt instrument GUIs so serial, USB, TCP, and SCPI hardware failures do not freeze widgets, hide stale data, or leave operators guessing.
Firmware habits that make bring-up easier, expose faults earlier, and keep common embedded failures from hiding in drivers, interrupts, buffers, or timing code.
A practical comparison of free PCB design tools, with attention to workflow, libraries, manufacturing output, privacy, current free-tier constraints, and the mistakes that usually hurt first boards.
Ten C++20 features that make everyday code easier to review, harder to misuse, and more practical to maintain in real projects.
Learn the real tradeoffs behind C++ containers. Compare performance, memory usage, allocation behavior, and practical considerations for desktop software, Qt applications, Linux systems, and embedded firmware.
