Микросервисы(async single-threaded) в эмбеддед. OpenBMC и рефакторинг «кошмара на С++» с помощью ИИ
Я всегда знал, что разработка для встраиваемых систем (embedded) является не тривиальным делом, но даже не представлял, насколько С++ код в реальных…
I Built an Open-Source J1939 CAN Bus Emulator (Because Vector Tools Cost Too Much)
If you've ever tried to test J1939 diagnostics tooling, integrate a telematics app, or just learn how heavy-duty vehicle networks work, you've proba…
The rules I build by
New here? Start with the overview . Before the rules, a debt. These are not mine alone; they are the labor of a whole career, and every one of them…
Building a MIL-STD-188-110 HF Modem in Modern C++: An Introduction
A weekly deep dive into a fixed-frequency serial-tone waveform, one block at a time. High-frequency (HF) radio is the communications system that ref…
How Does Call Noise Reduction Work on a Single-Microphone Phone?
On a phone with a single microphone, call noise reduction cannot work the way it does on flagship smartphones. There is no second microphone signal…
До вайб‑кодинга оставалась четверть века…
В 2000 году я писал на ассемблере софт для проверки приборов спутникового слежения и был уверен, что серьёзные системы дела…
Web Developer = Embedded Developer: Real PHP Now Runs on the ESP32 (v1.0.0)
If you can write index.php , you can already program a microcontroller. That's not a metaphor. PHP on ESP32 just hit 1.0.0 — the first official rele…
Kernel & Embedded News: Arm64 Drops Big-Endian, Boots CPUs in Parallel
Arm64 platform direction dominated this week: Will Deacon posted v2 of the series that removes big-endian kernel support, aimed at Linux 7.4, and a…
What the Arduino VENTUNO Q Signals for Local AI and Robotics
What the Arduino VENTUNO Q Signals for Local AI and Robotics Arduino’s VENTUNO Q is a clear sign that edge AI hardware is moving beyond simple infer…
What a Linux Safety Certification Actually Covers
A Linux safety certification is a statement about one defined software configuration running on named hardware, assessed by a named body. It is not…
Every Millimetre Is Spoken For in a 2.4 mm BLE Logging Card
A sealed logging card is a thickness problem before it is an electronics problem. Every subsystem sits downstream of one decision: how the millimetr…
Evidence-Grade Telemetry: Sensor Sync, Time Bases and Idempotent Ingestion
If you are building the ingestion side of a cold chain or asset tracking platform, there is a category of bug that does not show up in staging, does…
vm5277: Java-синтаксис и ООП для 8-бит МК без оверхеда
Java-синтаксис на 8-битных микроконтроллерах? Без виртуальной машины? Исторически в эмбеддеде правит Си. Но Си — это вечные malloc / free , утечки п…
Building an Industrial HMI and Edge Controller on STM32 with FreeRTOS and Modbus TCP
Building an Industrial HMI and Edge Controller on STM32 with FreeRTOS and Modbus TCP Industrial control demos are often judged by the screen. The mo…

The State of Automotive Grade Linux in 2026: Which Release to Build
The Automotive Grade Linux distribution is not one release on one baseline. As of 26 August 2026 its release-notes page documents three listed relea…
systemd vs BusyBox init: Which Init System Fits Your Device?
For most embedded products with a fixed set of services and no user-installable software, BusyBox init is the right default: small, no dependency ch…
Pi Zero + MPU-9250: empty i2cdetect is a 3.3V problem, not a Python library
I keep seeing Pi Zero + MPU-9250 threads where SDA/SCL look right and i2cdetect is empty — or the GPIO dies after a 5V VCC. Pi GPIO is 3.3V tolerant…
Driving an Undocumented 3nm ASIC with an ESP32: Inside the First Sub-10 J/TH Open-Source Bitcoin Miner
Next week we ship the Bitaxe Naja Duo , and the spec that matters is 9.5 joules per terahash at stock. First open-source home miner under 10. But th…
Buildroot for Embedded Linux — Part 1: Your First Buildroot Root Filesystem
Buildroot builds a cross-compiler, a Linux kernel and a complete root filesystem from source, driven by one Kconfig-style configuration file. Starti…
In-Tree vs Out-of-Tree Driver: Where Your Code Should Live
For hardware your company owns and intends to ship for years, default to putting the driver in mainline and carrying only the part you have not land…
The Linux DMA API: Coherent and Streaming Mappings Explained
The Linux DMA API exists because the address a device uses is not the address the CPU uses, and because on most embedded SoCs the CPU cache is not k…
Device Tree Ownership Is Moving Up Into Firmware
On most embedded Linux products the kernel carries the description of the board. Under Arm's SystemReady Devicetree band it does not: the platform f…
