I do not use books for engineering work and never will, because doing the work of thinking for myself is how I maintain the neural capacity for forming my own original thoughts and ideas no writer has seen before. If anyone gives me an opin

From my perspective they spread FUD about open source licensing. QT core is LGPL3. Many applications would be fine with using LGPL3 in commercial applications. Read QT's landing page on licensing, and fossa has a good block post on re

I'm not familiar with that definition, I typically see debouncing used as any means to filter out the state as it is changing from the mechanical action. I've seen simple BSP debounce example code that affects latency for both pre

This post inspired me a few years ago to start a very impractical learning side project. Most keyboards don't overly prioritize latency. Development of a keyboard is easy using a USB stack from the manufacturer, but it might not priori

ptp is <1us synchronization. From my testing NTP is ~20-60us after about 10 minutes of sync, but it intentionally drifts the phase around. On average, NTP is pretty close. If you look at the white rabbit FPGA PTP updates, its in the ns
