Embedded Systems & Electronics Engineering
General programming topics and techniques used in embedded and desktop projects.
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.
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.
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.
Ten C++20 features that make everyday code easier to review, harder to misuse, and more practical to maintain in real projects.
How to choose the right const-related C++ keyword based on the guarantee you need, with embedded-focused notes on API mutation, compile-time evaluation, startup initialization, and toolchain support.
A safer C++11 matrix implementation using contiguous storage, RAII, templates, and basic operations such as addition, multiplication, transpose, and identity matrices.
