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…
[Перевод] Улучшения Embedded Swift, грядущие в Swift 6.4

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…
Засовываем VLA на гуманоида: как выбрать платформу, модель и планировщик
Год назад на проекте гуманоида с Jetson Orin на борту меня регулярно спрашивали одно и то же. “Можно ли гонять нашу VLA локально, без сети?” VLA это…
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…
LighthouseReckoning: A Lightweight LoRa Mesh Network for Arduino, ESP32 and RP2040
LighthouseReckoning LighthouseReckoning is a lightweight LoRa mesh networking library for Arduino-compatible microcontrollers, currently tested on E…
ZBFun: архитектура для ZigBee без обязательного облака на Python
Меня зовут ZolAnd, я - независимый инженер-разработчик embedded-систем в основном для дома и сельской усадьбы. В какой-то момент мне захотелось собр…
How to Use the SH-C30L USB-to-CAN Adapter with Arduino UNO and MCP2515
Controller Area Network (CAN) is one of those technologies that quietly powers a huge number of embedded systems. It is commonly found in cars, EVs,…
Уменьшали как могли: сделали микроминиатюрный SOM на базе Linux (NAPI Slot) и промышленный шлюз на его основе
Когда речь идет о промышленном сборе данных, даже компьютер-одноплатник иногда избыточен по габаритам. Если устройство встраивается в щиток, в корпу…
Reverse-Engineering SWIO: Why Existing CH32V003 Programmers Fail and How I Built One That Works
I wanted to see if an ESP32-S3 could be used as a programmer for the WCH CH32V003 instead of using a dedicated WCH-Link. The final setup is: PC → ES…
Нельзя просто взять и прочитать 64-битный SysTick на CH32V203
Когда я начал работать с CH32V203G6U6 и обнаружил, что там есть 64-битный аппаратный таймер, то подумал: ух, это же отлично, раз таймер аппаратный,…
Remote Diagnostics for Low-Power IoT Devices: Stop Treating Them Like Servers
The hardest failures in low-power IoT are often not total silence. They show up as partial signals: battery voltage drifting down, RSSI getting wors…
Choosing a Root Filesystem Format for Embedded Linux
Your storage hardware narrows the choice first: raw NAND requires UBIFS on UBI; ext4 and f2fs are not candidates there. On managed flash such as eMM…
Engeem: Как я сделал «двигатель в коробочке», пока отдыхал от мозгов для АКПП
Привет, хабр! Помните мою прошлую эпопею про создание ATCU-ESP32 — мозгов для АКПП, которые умнее заводских [источник: статья на Хабре]? Так вот, по…
Локальная база на клиенте: Blazor WebAssembly и MAUI на SQLite — без EF DbContext, Include и миграций
Офлайн-хранилище со сложным графом и outbox: быстрый старт в MAUI и в браузере, базовые операции и почему в этой роли EF Core только мешает. Курьер…
The Mindset Behind Hard Debugging
Hard debugging is rarely defeated by a lack of tools. It is defeated by three quiet habits: assuming the fault is where the symptom appears, clingin…
