It’s 11 PM and the board on your bench still won’t boot. The MCU has power and the clock is running, but somewhere on the I2C bus, a byte is missing, and you have no clue where. Twenty years ago, solving this meant walking to a lab that had a logic analyzer bolted to a […]
Picture this like Eighteen months after your team buys a UFS protocol analyzer, a new SoC project kicks off. Different device vendors this time, different firmware team, and the DUT has no accessible test points where your existing probes expect them to be. The analyzer that worked perfectly for your last project suddenly can’t reach […]
UFS vs NVMe vs eMMC: How to Pick the Right Storage Interface If you ask ten embedded engineers why they picked UFS over eMMC, or NVMe over UFS, most of them will say the same thing: it’s faster. Now, ask them what “faster” actually means, and we can guarantee that the answers you get will […]
Two wires. That is all I3C gives you. Two wires carrying a clock and a data stream, the same physical interface engineers have been probing since I2C arrived in 1982. Open a capture and the waveform looks familiar. The muscle memory from a decade of I2C debug kicks in before the conscious mind catches up. […]
There’s a particular kind of engineering post-mortem that nobody wants to sit through. The one where a device passed every single lab test, shipped to a customer, and then failed in a way nobody anticipated. When you tested it, the traffic looked clean, the enumeration worked, and your reads and writes completed without a single […]
Somewhere on your PCIe bus, a device announced itself. It sent an ID. It claimed a vendor. It asked to be trusted. And your system, without question, without verification, even said yes. That approach made sense for a long time. Components came from known vendors, supply chains were shorter, and the threat model stopped at […]
I3C vs I2C: What Actually Changed and Why Engineers Are Making the Switch Most embedded engineers have lived through this. You’re twelve sensors deep into a design, the bus is clean, and everything communicates well. But then you add one more device and discover it shares a static address with something already on the board. […]
Inside every modern electronic device, there is a protocol running, and most people have never even heard of it. This protocol does it all. It moves data between chips; it keeps the sensors talking to the processors. It has been doing all those things reliably since 1982. That protocol is the I2C. However, after more […]
There is a particular kind of silence that every hardware engineer dreads. Not the silence before a presentation or before a code review. The silence after you apply power to a new board for the first time, and the device doesn’t respond. The bus is quiet. The enumeration never happens. We’ve been in that room […]
