So I have this one small Arduino task for perform in a project at work & I've received som rudimentary instructions but the task is simple & I'm pretty sure I can do it...
-
I've been coding for over 40 years and I still spend hours or days learning and being puzzled.

@fastness I know, this much I found out - but it does nothing to save the code already running on the device, or enable me to roll back to it if I messed up...
@jwcph
I've been playing with Arduino/esp32 a little bit, but I've never heard of a way to get the binary code off a device. Might exist, but also might not, it's not a common use case.Depending on circumstances, can you put your code on a replica device that you switch in when you've got it doing what you want?

@niels @fastness No, I can't do that - I only have one device
I want to challenge the "not a common use case" thing, though, because OF COURSE it is!
Literally every single user, ever, would benefit, if only just from knowing that the option existed to back up & later restore previous work before overwriting it.

@niels @fastness I would contend that not a single person writing text in the entire world would prefer NOT to have the "undo" option.
You say you don't like doing it - but you can't; the option isn't there. I don't know you, but I honestly doubt that if the option did exist, you wouldn't benefit from it at all. If so, then you're probably pretty unique
It's like, I like seat belts in cars, too, even though I've thankfully never had my life saved by one.

@jwcph
I feel very unique
Anyways, it seems like there are a few tools available, maybe they can work for you?

@fastness@niels @fastness If I was doing this for my own sake, because I wanted to learn Arduino (which I might, at some point), I think those could be helpful, thanks
For this project, however, they're way "over budget" - I can easily see myself spending 1-2 days finding out & understanding how even one of these approaches work...
I guess I'll just have to gather up my courage & overwrite it
