Day 158 of 200: Interrupts in Embedded Systems In the world of embedded systems, every millisecond counts. That’s where interrupts come in. Instead of constantly checking if an event has occurred (polling), interrupts let the system pause its current task and immediately respond when something critical happens like a button press, a sensor trigger, or incoming data. Why Interrupts Matter: • Efficiency → Save CPU cycles by avoiding constant polling. • Responsiveness → Immediate reaction to real-world events. • Scalability → Handle multiple tasks smoothly in real-time. Applications: • Keypad input in ATMs • Motion detection in smart security systems • Engine control in automobiles

Most RTOS kernels still rely on tick-based scheduling which can introduce unnecessary interrupts, wasted energy, and limited timing resolution. embOS-Ultra from Segger removes the tick entirely, replacing it with cycle-resolution timing. The result is deterministic, extremely precise scheduling, ultra-low power operation, and full backwards compatibility without any code changes needed. For embedded engineers, this means longer battery life, higher precision in real-time control, and seamless migration from existing RTOS setups. If you’re at Electronica India 2025, Hall 3 B45, meet our Segger team and learn how embOS-Ultra can redefine your system’s timing model.
Your system misses a deadline. Then another. Suddenly, your embedded device feels... sluggish. That’s how timing issues sneak in. Quietly at first, then all at once. Traditional #RTOS solutions rely on tick-based scheduling, which wastes CPU cycles waiting for the next tick — even when nothing needs to happen. That’s where embOS-Ultra changes the game. Built with Cycle-Resolution Timing, embOS-Ultra schedules tasks exactly when they’re needed — no sooner, no later. The result? ✅ Less CPU overhead ✅ Faster responsiveness ✅ Longer battery life It’s a smarter way to run real-time systems: precise, efficient, and built for today’s demands. Swipe through the slideshow to see what embOS-Ultra can do. To learn even more about embOS-Ultra, please visit: https://lnkd.in/eGEw3WNH

Sandisk announced one of the industry's first 256TB solid-state drives with UltraQLC platform (high capacity, high performance, and high reliability). U.2 form-factor, a multi-core controller, custom firmware, as well as 2Tb BiCS8 3D QLC NAND memory. BiCS FLASH™ generation 8 high performance and high memory density 3D flash memory. Data are transferred to outside with 3.2Gbps speed, while data are read and programmed inside with 40μs time and 205MB/s throughput, respectively. UltraQLC have Direct Write QLC technology, which allows the controller write data directly to QLC memory, not via a pseudo-SLC buffer which enables power-loss–safe writes on the first pass. This design should simplify the writes and reduce latency. Pairs nicely with Hammerspace.

🚗💥 𝐀 𝐝𝐞𝐥𝐚𝐲 𝐨𝐟 𝐣𝐮𝐬𝐭 30 𝐦𝐢𝐜𝐫𝐨𝐬𝐞𝐜𝐨𝐧𝐝𝐬 𝐜𝐚𝐧 𝐝𝐞𝐜𝐢𝐝𝐞 𝐛𝐞𝐭𝐰𝐞𝐞𝐧 𝐥𝐢𝐟𝐞 𝐚𝐧𝐝 𝐝𝐞𝐚𝐭𝐡! That’s the reality inside your car. When a crash happens, the embedded system controlling the airbag has only microseconds to react. Here’s what actually goes on 👇 👉 Sensors (accelerometers, gyros) detect a sudden deceleration 🚨 👉A microcontroller calculates if it’s a real crash or a false alarm 👉If yes → it instantly triggers the inflator to deploy the airbag 🛡️ All of this… happens in less time than it takes you to blink (≈100 ms) Why microseconds matter: ❗If the airbag opens too late → it’s useless. ❗ If it opens too early → it can harm the driver. ✔️Precision timing = lives saved. 🛠️ How do firmware engineers build such systems? 👉Writing highly deterministic, low-latency code (often bare-metal or RTOS) 👉Using hardware timers & interrupts for microsecond accuracy 👉Implementing redundancy & fail-safes to avoid false triggers 👉Testing across millions of crash simulations to ensure reliability 💡 Next time you sit in your car, remember: an invisible embedded system(reactive or proactive) is sitting silently in your steering wheel… ready to protect you in microseconds. 👉 What fascinates you more, the hardware that senses or the firmware that decides?

🚀 Beyond the Button: The Unseen World of MCU Resets 🚀 When you hit the reset button, it feels simple. But under the hood, MCUs have multiple reset mechanisms, each designed to keep your system reliable, no matter what chaos hits. Here are the key reset types every embedded engineer should know: 🔋 Power-On Reset (POR): Every boot begins here. Ensures the MCU starts clean and stable when power is first applied. ⚡ Brown-Out Reset (BOR): When voltage dips below a safe level, BOR steps in to prevent unpredictable behavior. ⏱️ Watchdog Timer Reset (WDT): If software freezes or goes rogue, the watchdog bites—forcing a reset to recover. 🖲️ External Reset: The classic manual reset. Triggered by a button (or external circuitry) to restart the system instantly. 👉 Why it matters: Resets are more than restarts—they’re the invisible guardians of system resilience. Without them, even the smartest firmware can fail in the face of power glitches, bugs, or user actions. 💡 Next time you press that reset button, remember: It’s just one doorway into a whole ecosystem of protections keeping your system alive.
