Link to Mark Owen’s excellent QFP library for soft float on Cortex-M0+ (ARMv6-M) and Cortex-M3/M4 (ARMv7-M).

Nice write up here, too, I like the idea of a firm float.


My feeling about programmable IOs is they’re fun, but not the right choice for commodity high speed interfaces like USB. You obviously can make them work, but they’re large compared to what you would need for a dedicated unit. The DVI over PIO is a good example: showed something interesting (and that’s great!) but not widely useful. Also, a lot of protocols, even slow ones, have failure and edge cases that would need to be covered. Not to mention the physical characteristics, like you’ve said for high speed USB.


This is true, but only relevant if you order enough units (>100 k? Depending on price & margin of course) to customize your die. Otherwise, you have to find a chip with the I/Os that you want, all the rest being equal. Good luck with that if you need something specific (8 UARTs for instance) or obscure.


I haven’t heard a peep about conscription, can you provide a source? There was some vague national service proposal for school leavers a couple of years ago, but that was it.



One person in the Lords raising the issue in no way constitutes widespread calls for conscription.



Maintainance and upgrades. These big shared facilities they are shutdown regularly and researchers work flat out while they're up.


Doesn't power costs also affect shutdown periods? I know that CERN would shutdown in winter due to increased power costs and power demands around then. I suppose something similar may affect accelerators in the US.



I read this with a large /s on the end...


Fair point - yet the very official US stance is to reduce regulation and what not. If it was the sarcasm, it'd be the "US population". I could contribute 'tremendous' for obvious reasons but still.

That would likely the 1st time to miss sarcasm... need few more words not the '/s' (I never use /s)


Hah, also fair point - there are plenty of people who would say this completely earnestly! :)


Maximum power output and maximum (assisted) speed are generally legislated. In the UK, an e-bike is up to 250 W and 25 kph. More than that, it would classify as a motorbike and you'd need a license (not particularly onerous). The bike itself is often built differently to accommodate the different power profile.

As a pedal cyclist, I feel that's a reasonably sensible limit as much faster than that you should be more experienced as a cyclist to control the bike and anticipate the conditions.


Why not? It's a factual report stating that the AAIB has opened an investigation into a potentially dangerous incident. There's not any editorial bias evident. See other extensive comments as to why this is not just a case of "it landed, so what's the problem?".


Sensational headline completely missing the point.


Based on the title, I was hoping this would be a new subclass of tower defence. Vibe coded, naturlich.
