Why is that obvious? My brain’s been infinitely recursing for years as far as I know
rabryan··on How to flash an LED: writing ARM assembly for an STM32 microcontroller
Yeah I love those. They highlight features xyz on first page of datasheet. Then on the last few pages its like btw features xyz dont work on rev A-F. And your supplier doesnt know what revs they have...

I’ve used their accelerometer (LIS2D). Performance and specs are great - it was just a pain to develop the embedded interface with it because the documentation had a bunch of mistatements and was missing critical information (a weak pullup on a certain line caused a bunch of current consumption - took days to figure out). Also they had an off by one bug in their LIFO queue that took a long time to figure out. Once you getting it working its great. Last time I checked they still hadnt updated their documentation with what I reported to them...

Atmel (now under Microchip). They have great documentation and software libraries. And they actually acknowledge hardware errata in the documentation.

Avoid ST at all costs in my experience. Their documentation is terrible. They never acknowledge hardware errata even after clear evidence of it. They’re not a company with a solid engineering culture imo

Definitely an okay sentiment in my opinion. First world countries haven’t had to face reality in a while apparently...

Its an s-curve with parameters that are changing by the hour and is sensitive to so many other variables. I’m definitely advocating as extreme a response as possible, but I see those numbers more as a pessimistic upper bound (necessary for people to take appropriate action).

And I as well hope things are changing quickly...

Millions? Where and when? Plus why criticize something thats advocating staying home in order to save lives.
