Hunting a Memory Leak that Crashed Remote Devices
Credit: www.blues.com Introduction Imagine a fleet of embedded devices deployed across the country, running smoothly for weeks—until, without warning, they stop communicating. That was the mystery we faced when a customer reported a baffling issue in their widely deployed product. After extended uptime, devices would suddenly and silently stop communicating with the central server. The […]
High-Precision Multi-Sensor Temperature Monitoring System for Pharmaceutical Testing with MQTT-Over-Ethernet Connectivity
Introduction: This PCB module version 2.0 was designed as an upgrade for a dissolution tester to measure temperature using sixteen (16) individual PT100 temperature sensors. The previous version supported eight (8) sensors and lacked central network ethernet connectivity. The update was aimed to enhance sensor capacity, add network connectivity via ethernet (IEEE 802.3 standard), support […]
Development of Wearable Headset for Fatigue and Drug Detection
Project Overview This case study presents the development of an advanced Pupilknowlogy system designed to measure Pupillary Unrest Index (PUI) and Pupillary Light Reflex (PLR) for the detection of fatigue and drug influence in subjects. The project integrated hardware and software components to create a comprehensive, portable solution for use in clinical, research, and law […]
Coredump Can Help You with Embedded Firmware Debugging (Better than Breakpoints)
Source: embeddedcomputing Coredump captures the crash moment of an embedded system. It shows memory, registers, and stack traces. Firmware bugs are tricky. Hardware-software interactions are complex, resources are constrained, and runtime behavior can sometimes be unpredictable. For teams working on developing embedded products, this can feel like navigating in the dark. To reach the core […]
How to Select the Right Microcontroller for Your Embedded System?
Choosing the right microcontroller is like laying the foundation for your embedded system—get it wrong, and you risk delays, cost overruns, or an outright redesign. The microcontroller (MCU) you choose will determine not just the technical feasibility of your product but also its cost, scalability, and long-term reliability. And there is no free lunch and […]
Design Guide for Battery Safety in Wearable Electronics
Wearable devices often use Lithium-Ion or Lithium Polymer batteries, which have a high flammability risk. This is due to higher energy density and the use of flammable electrolytes inside Lithium-based batteries. Safety against fire and explosion is critical in wearable and consumer electronic devices (this goes without saying). But how do the designers ensure […]
eSIM – Its Benefits & How to Integrate it into Your IoT Hardware
An eSIM (embedded SIM) is an alternative to a traditional SIM (Subscriber Identity Module) card. Unlike traditional SIM cards, eSIMs do not require physical swapping to be reprogrammed for a different cellular network provider. In this blog, when we refer to eSIM, we mean an IC that can be soldered onto your PCB, such as […]
What is Model-Based Development – and How to Use it For Generating Production-Ready Code?
Model-Based Development (MBD) offers a way to design embedded systems by using visual models instead of traditional coding. Model-based development tools generate production-ready code, reducing manual errors and compliance issues. This guide will walk you through the basics of Model-Based Development, its advantages, challenges, risks and a tutorial for developing embedded systems from start to […]
