Practical guide to testing embedded firmware on your host machine using mocks, QEMU, Zephyr native_sim, and hardware-in-the-loop. No dev kit required for 80% of your tests.
I write C for microcontrollers. My code talks to SPI peripherals, configures DMA channels, and runs...
A practitioner's guide to hardware abstraction layer design in embedded C — comparing Zephyr, STM32 HAL, Arduino, CMSIS, and hand-rolled approaches, with concrete GPIO and SPI examples you can steal.
What the 2021-2024 chip shortage revealed about firmware architecture, and why the teams that invested in portability survived while others scrambled.
Step-by-step guide for migrating firmware between MCU families — from dependency audit to testing. Covers STM32 to nRF52, ESP32, and TI MSP432 migrations with real examples.
Real firmware porting mistakes I've seen engineers make when migrating between STM32, ESP32, nRF52 and other MCU families — with C code examples showing the problem and the fix.
Under Arm SystemReady and EBBR, a firmware-provided device tree moves board ownership to the platform and makes firmware update a requirement, not a choice.
