How proficient do you rate yourself in your most coded language? (sh.itjust.works)

Hi,

My question certainly stems from the imposter syndrome that I am living right now for no good reason, but when looking to resolve some issues for embedded C problems, I come across a lot of post from people that have a deep understanding of the language and how a mcu works at machine code level.

When I read these posts, I do understand what the author is saying, but it really makes me feel like I should know more about what's happening under the hood.

So my question is this : how do you rate yourself in your most used language? Do you understand the subtilities and the nuance of your language?

I know this doesn't necessarily makes me a bad firmware dev, but damn does it makes me feel like it when I read these posts.

I get that this is a subjective question without any good responses, but I'd be interested in hearing about different experiences in the hope of reducing my imposter syndrome.

Thanks

What are you working on and what kind of organization? Are you working with someone more senior? You could ask him or her for an assessment of where you should work on strengthening up.

You are in the right mindset if you are worried. Many C programmers greatly overestimate their ability to write bug-free or even valid (UB-free) code.

The AVR MCUs are pretty simple compared with 32 bit MCUs, so are good for asm coding.

Otherwise it's a matter of coding til it's reflexive.

Philip Koopman has written a book on MCU programming that sounds good. I haven't seen it yet but someday. You might look for it: https://betterembsw.blogspot.com/2021/02/better-embedded-system-software-e-book.html?m=1

John Regehr's blog is also good.

Thanks for your input.

I think I would like to follow all these people and their work on C, and their in depth knowledge. But free time is sparse, and I don't have the mental energy when I do have some time.

As for my work, I work in a startup where I am the only one doing what I do. However, I have a lot of leeway in how I code, so I am always somewhat read on best practices. So I can't really refer to a senior dev, but I can self-teach.

I think I coded enough that a lot of what I do is a reflex, and I often can approximate a first solution,but I have doubts all the time on how I implement new features. That makes it so that I am a slower coder and I really struggle to do fast prototyping.

I am aware enough of what I do well, and what I struggle, so there's that.

Fair enough. If your product isn't safety or security critical then it's mostly a matter of getting it working and passing reasonable testing. If it's critical you might look for outside help or review, and maybe revisit the decision to use C.

The book "Analysable Real-Time Systems: Programmed in Ada" was recommended to me and looks good. I have a copy that has been on my reading pile for ages. I was just thinking about it recently. It could be a source of wisdom about embedded dev in general, plus Ada generally fosters a more serious approach than C does, so it could be worth a look. I also plan to get Koopman's book that I mentioned earlier.
