I have seen a lot of unreadable code. Most of the time if I want to use it I try to make it readable, at least for me. Out of all the times I have done that, there was only one instance where I found the results to be slower than the original. That was quite a while ago and compilers have come a long way since then.

"at least for me" being the operative bit of that. i know my code isn't as readable as it should be because of how many people tell me my articles lose them.

In the past I have written code that seemed readable at the time but when I came back to it a few months later was unintelligible to me! it worked fine but how I did it, I have no idea!
- I would love to change the world, but they won’t give me the source code.

I have inherited a body of code from a guy who retired about 10 years ago and then died. He was a grade A a-hole to work with while he was here. After he left his code bounced from person to person, with none of them making any changes, until it arrived on my desk. I have spent a couple hundred hours over the last year just looking at it in the course of diagnosing issues. I am currently about to make my first change in it due to a hardware obsolescence problem.
This is all C, running on Windows as a command-line app. The code was deliberately written so that A-hole was the only person who could maintain it. Identifiers are of minimal length. There are global values with single lower-case character names. While there are dozens of .C source files, none of them have matching .H files. All external references are explicitly specified everywhere. Function prototypes are not used - anywhere. Magic numbers abound. Pointer arithmetic is used unnecessarily and unwisely. There's more, but I don't want to frighten you children.
He cultivated a mythos surrounding his code, claiming that it was difficult and performance-intensive, and that was why other people couldn't handle it. His management believed it.
I have spent the last two weeks figuring out how to address this obsolescence issue. When I'm done, I will have replaced <100 lines of code with around 40.

Writing unreadable code is inexcusable and should be grounds for termination with utmost prejudice.

I've found there are cases where code is bound to be ugly no matter what. Either the interface the code must integrate with is nasty (using the unfortunately undocumented soc/spi_master.h on the ESP-IDF), or the algorithm is horrific (LALR table generation) and there's little choice, plus comments only get you so far because you'd have to explain the entire thing you're coding against (like the LALR algorithm, or you'd have to document the undocumented interface as well as your own code)
So for certain things, I forgive ugly code, as long as it is otherwise well written.

I've been trying with no luck to read data off of a couple of different SPI devices.
It turns out, the documented API for doing SPI with the ESP-IDF is not very capable.
There is a lower level API that both the higher level API and the Arduino framework layer are built on top of. It is undocumented.
Worse, it's Apache licensed, meaning just for me to figure out how it works, I get roped into their licensing scheme because I have to look at their code and make something based on it.
It does me no good if you build layer upon layer of API and then hamstring the top layer and don't document the lower layers.
And now I get to go cave diving. Here there be dragons.

Does the recent case with Oracle and Google(?) exempt you from this licensing scheme? I thought it was decided that an API couldn't be copyrighted, just its implementation. Regardless, it is bizarre for an API to infect users with an undesirable license.

It's only if I understand the license properly and because I'm essentially forced to create a derivative work in lieu of documentation. I'm not sure how that court case impacts this.

You can always bit bang the SPI.
|

I'm basically resorting to something like that, but for production I need to use the hardware SPI controller w/ DMA for performance reasons. I think I can get there with my current route, even though it's not ideal.

Fear not!! As a fan of The Hobbit, I know the ogres were turned to stone and Smaug is dead.
Actually, best of luck!

Well it amazed me ...
I'm trying to do Daily Objectives every day (got the 7-in-a-row award yesterday!) but one of today's was "Recruit a member to your MC" and since I have no friend who play computer games I was a bit stuck.
So when at last I asked a random member if he'd mind joining for 30 seconds and he said "Sure! I'll finish this heist prep and get back to you" I was gobsmacked!
And he did - so now I have 8 days in a row! Only 20 to go for the "big reward" but I doubt that'll be possible - at least one is going to require me to buy a submarine or something ... 
So it's true: not everyone playing GTA V is a griefer on an Oppressor II!*
