I don't support bit banging, it just means you haven't used the right chip/integrated correctly (at least nowadays where transceivers increase the cost of your product by less than a buck) but other than that I don't see anything unreasonable about their job description?

In east london, sure. £30k is much more difficult than £40k though, obviously. But £40k is easily doable.

30k would be difficult now if you are single and quite happy to live in a studio or one bedroom to be honest. Particularly if you want to do anything more than exist and actually get yourself out of that situation.

I have three kids and a 3 bed house in a nice bit. This is incidentally why I'm not doing EE work! Fintech pays the bills better.

Reminds me of the typical procedure. Asking for skills 80k worth, but only paying 40k incl. all overtime. If they don't find anyone they'll moan about skills shortage. And if you ask why the salaries aren't increasing due to the alleged skills shortage you won't get an answer. Don't sell yourself under value!

That's pretty much it.

You'll also get the startup equity sob story: "Dude, it's going to be awesome, and when it is we'll all be loaded. All we need you to do is work for us for free for 6 months and we'll give you 5% equity in our top secret startup. We're going to make a killing, all move to SF and get an IPO. Then it'll be drinks on Mars with Musk.". When you turn up on your first day, you find it's a social network for cats or something.

I worked for one of those outfits once for an entire DAY and told them to fuck off.

"Bit banging should be the name of your favourite band"

Bit banging is a work around, when hardware for a specific protocol isn't present, not a go to favourite idea!

Worst example of this I have seen is the BeagleBone Black, I haven't used it in a while but when I last looked they just bit bang everything with the processor instead of using the dual built in PRUs and their relevant hardware.

I think the idea is that it shows imagination to work around a problem rather than give up and use a more expensive part. It also shows better understanding of hardware, which is one of the most important skills for an embedded programmer.
 
If you were interviewing someone for a job and asked them to sketch out a volume product that needed 4 SPI ports, the candidate who suggested using a cheaper micro and pointed out that only one of them needs to be fast so the others could be bit-bashed, or explaining how they the SPIs could be done using DMA ought to score better than the one that said the only option was to use a higher end part that had 4 SPIs and a ton of stuff that wouldn't be used.

Just wondering... If you're ultra-competent in all that, what do you become when you extend those skills?

Whenever I've seen hyperbolic phrases like "ultra competent" (and haven't been able to simply "walk away"), over time the perpetrator has revealed themselves to be full of bovine excrement. Any such phrase should be an orange flag.

Standard technique: take a statement and invert a word/phrase. If the result is meaningless or stupid, then the word/phrase can be removed without loss.
There are lies, damned lies, statistics - and ADC/DAC specs.

I know a lot of competent people. None of them would call themself "ultra competent". Maybe not even competent. Probably something like "more or less capable".

We're engineers. Not car salesmen. The best indicator of competence is the realisation how little you know.

It is also notable that the more people know, the more they realise they don't know. The inverse of the Dunning-Kruger effect.

The reverse is also true. A microcontroller which has too few resources will need a massive amount of development effort to make everything work. That is not a good fit for a lower volume product (and yes, too many think their product is going to be high volume) and there is also a chance product enhancements cannot be made without a major re-design. All in all you need someone who runs some number on effort versus budget before selecting parts.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Worst example of this I have seen is the BeagleBone Black, I haven't used it in a while but when I last looked they just bit bang everything with the processor instead of using the dual built in PRUs and their relevant hardware.

Bit banging should only be done with bits that are at least 16 years old and that have given meaningful consent.

But seriously, except for trivial cases, it usually means that the perpetrator can't read a data sheet well enough to realize how to use an on-board peripheral, or even to recognize that there is a suitable on-board peripheral.

There can sometimes be justifiable circumstances for doing it. I've bit banged SPI for an LTC2400 ADC when I also had an SPI LCD and only one dedicated hardware SPI interface. When they shared a bus, driving the LCD injected noise into the ADC during conversions, even though it wasn't selected. I got rid of about 200 ppm of noise by creating a separate SPI interface by bit banging the LTC2400.
Anybody got a syringe I can use to squeeze the magic smoke back into this?

The peripheral doesn't always work, correctly. Protocol standards can change over time and/or otherwise give rise to combinations that simply don't work together, out of the box.

Maintain a hodge podge of hardware and firmware created by other engineers who we can't pay enough to care to lift a finger. Be an expert in teaching/presenting your inherent value to other people so we don't need you the second you are not perfectly pleasant and charming and positive to work with. And do it for 30K. The salary was like a punchline to a joke. This is depressing to anyone with any of these skills.

It's still there, I wonder if they got anyone to save us.
