Understanding IEC 62304 Compliance for Medical Device Firmware Development
Introduction
Introduction Every embedded systems engineer faces a fundamental architectural decision early in a project: should the firmware run on bare metal or on a real-time operating system (RTOS)? For decades, bare metal super-loops dominated the microcontroller landscape. A simple while(1)…
When choosing a microcontroller for industrial applications, engineers often face the dilemma: STM32 vs ESP32? Both are popular ARM-based microcontrollers, but they serve different purposes. In this comprehensive comparison, we’ll help you decide which is better for your specific industrial…
