STM32 isn't the only Cortex-M microcontroller series in the world, you know. They're popular because they're pretty decent, low cost, have good dev boards and offer a wide variety of parts. However, their software sucks (okay, so do all of the other options...), their peripherals are not as good as some of the other options (in particular I'm thinking of peripheral clock trees when I say this, among other things), an…

Are you in the US? Because EU is full of embedded devs.

> The current chip shortage has claimed 6 of our firmware devs, all hired by companies ready to spend just any money for anybody "who can replace that ____ing STM|NXP|Renesas thing" Condolences on the loss of coworkers. But this seems interesting to software people who haven't been doing embedded, but who can wrangle C well enough to adapt (quickly?) to embedded constraints and interfaces.

Embedded development is more than just wrangling C, that would be like saying backend dev is wrangling EC2 instances ;). It's knowing how low level hardware operates and knowing how to dig yourself out of the various gotchas like for example figuring out that a last minute replacement of the crystal oscillator by the HW team with a cheaper one is now screwing up your boot process or that the reason your products are…

I hope an EE with a logic analyzer will help troubleshoot the clock problem, since I don't think the prevailing software methodology will work (i.e., ask on Stackoverflow, then add three dozen more Node.js packages to the firmware footprint). :)

I’m terrified about wearing out a flash on a unit I’m working on. I have a permanent break point in that code. Logically I know when a write is supposed to trigger, but oh man I’m paranoid I’m going to burn my prototype with a fat finger of something.

If you have a taste for irony, my company makes critical components for semiconductor equipment. If we can't ship, they can't ship. If they can't ship, semiconductor fabs can't increase capacity to meet the demand and solve the shortage. We went line down last week due to shortage of a critical chip for our component. In reality, the shortage is likely self-inflicted, like toilet paper a year ago, but for whatever co…

I guess it will always be possible to make critical components by delaying a customer's batch that would have been delayed anyway.

this is true for all appliances with any sort of networking. an appletv, roku, chromecast or fire stick have the exact same concern.

Yes, but the primary function of a TV is not causing the security vulnerability - the questionable additions are.

Not sure wanting a device to watch Netflix is questionable.

No, this is the result of people like Neill Ferguson forecasting that COVID would be multiple times worse than it turned out to be, and Governments and the media believing him. For example this report from March 2020 was highly influential and predicted 2.2 million deaths in the US in an 'unmitigated epidemic' scenario: https://www.imperial.ac.uk/media/imperial-college/medicine/s... When in reality the official COVID…

> For example this report from March 2020 was highly influential and predicted 2.2 million deaths in the US in an 'unmitigated epidemic' scenario: You just said yourself that the 2.2 million was the "do nothing" scenario, and as we've seen in India it could've easily been that. You also just said said we did many things — "unusual and unjustified" things, in your opinion — therefore mitigating that worst-case project…

Re: India. Look at their case curves per million. They haven't really had any epidemic until now. Their infections per mille stats are far below places like the UK. What we're seeing in India is COVID round 1 combined with a third world health system and third world air quality. This is a country that routinely has problems with respiratory illness and oxygen shortages in 'normal' times. It will get much worse before it gets better in India and that doesn't tell us anything about the accuracy of the predictions.

For that we need to look at all the data. People have done that. The predictions were always completely wrong in every case. Here's an article that examines the track record of that group at ICL:

https://www.aier.org/article/imperial-college-predicted-cata...

Re: "do nothing". Both ICL and a separate Swedish team applied the Ferguson model to Sweden and got a prediction of around 90,000 COVID deaths. True total: 98,000 deaths of all causes in total, and that was after 2019 was the year with the lowest mortality on record. Age adjusted, Swedish excess mortality matches that in 2012.

That's one famous example but again, all-data analysis shows the same thing. Lockdowns don't seem to affect the course of the disease:

https://thelancet.com/journals/eclinm/article/PIIS2589-5370(...

Epidemiology has developed a culture of bad science, presenting unvalidated models as indisputable fact and worst of all, pathological lying. Ferguson was recently caught doing it again:

https://www.telegraph.co.uk/news/2021/05/04/uks-covid-reopen...

As pandemic revisionism goes, it was really quite extraordinary. Asked on BBC Radio Four’s Today Programme about the latest data showing Britain is enjoying an eight-month low in coronavirus deaths and infections, Professor Neil Ferguson said on Tuesday: “The data is very encouraging, and very much in line with what we expected.” As it was on the radio it was impossible to tell whether this was said with a straight face, but we must assume it was ...

... Prof Ferguson’s team [had] warned: “A return to higher transmissibility levels after non-pharmaceutical interventions are lifted will also lead to a third wave of hospitalisations comparable in magnitude to the current wave” and called for mask wearing and hand hygiene to continue after full lifting. Under the February modelling which informed the roadmap, hospitalisations should be starting to tick up around now, but there is no evidence of that happening, with cases down 11 per cent in the past week ...

... The team warned there was no way out of a devastating third wave, with modellers arguing that even the slowest release in August would result in “substantial additional deaths” of around 56,900 by June 2022 ... One of the main errors in much of the modelling seems to have arisen from a misjudgement of how much schools would impact the reproduction number

The predictions of epidemiologists, not just Ferguson, were wrong by orders of magnitude and wrong in a way that has caused global supply chain disruptions. We should care more about the effects they had on restricting access to healthcare, because those actually killed people rather than just disrupting electronics supplies. But this story is about the latter. That's why it is wrong to vote down someone speaking the truth about the root cause: exceptionally bad science and our societies apparent inability to detect it or reckon with it.

People will wail and cry and scream about their freedom being taken from them...

Because it is in fact taking away their freedom

Yes: Their freedom to pollute the environment and to endanger other people's lives. Hey, there are laws against murder and robbery too. "How dare they take away my freedom to relieve others of their life and property!"

Perhaps it's time Americans stopped reacting like conditioned Pavlovian dogs to the mere word "freedom"? Not all "freedoms" are unequivocally good.

>Now find a single person who can program bare hardware on a short notice on above Arduino level. Wait, there's real money in that? Maybe I shouldn't waste my time just doing yard work. Sidenote: I just asked my wife about parts shortages at her workplace. Evidently you guys are right. I should get out more.

Yep, I'd say today is the best opportunity to get a higher paid embedded job than any time before if anybody specifically targets people hiring on urgency.

But a thing to remember is that people currently hiring themselves been likely neglecting their RnD before the crisis hit them.

That's happening in China. It's not that uncommon.

Regarding cars: "Some carmakers are now leaving out high-end features as a result of the chip shortage, according to a Bloomberg report on Thursday. Nissan is reportedly leaving navigation systems out of cars that would normally have them, while Ram Trucks has stopped equipping its 1500 pickups with a standard “intelligent” rearview mirror that monitors for blind spots" I have an unpopular opinion, especially when we…

I definitely agree that car size inflation is a real problem. Cars are too big and getting bigger every year. That said, "good visibility" is not a replacement for safety tech. The sensors and cameras in a car are always going to be better at spotting danger than a human for things like blind spot monitoring and backup cameras. You sound a bit like the teachers that would drill mental math because "you won't always h…

> That said, "good visibility" is not a replacement for safety tech. The sensors and cameras in a car are always going to be better at spotting danger than a human for things like blind spot monitoring and backup cameras.

One area where I strongly believe (yeah, personal feelies, no empirical study to back it up) misguided priorities have led to sub-optimal safety results is forward visibility. Some sibling comment mentioned "car didn't detect / erroneously 'detected' vehicle in front"... Since when do we need technology to "detect" vehicles in front of us; aren't we supposed to be able to SEE those, in order to be qualified to drive?!?

A: Since A-pillars have gotten as fat as your thigh, obscuring huge swaths of your field of vision.

Now sure, I understand that it's a good thing you won't get crushed flat if your car rolls over. But it's a bad thing if you crash into a vehicle, or run over a pedestrian, because you can't see out of your own vehicle. And how often do roll-over accidents really happen? My guess would be, a lot less often than collisions caused by impeded forward visibility.

(If my opinion that "visual aids shouldn't be necessary" in the forward direction makes me a "mental maths-advocating teacher", then so be it.)
