Nope.
It was related to the actual requirements (convert C++ code to C, not the opposite), only David apparently got it.
Actually I didn't consider the remarks in your code at first. Now it makes sense.

Indeed looks unusual, especially considering that proposed C++ programs are very, very C-like.

Maybe he meant "real" C
main(argc, argv)
int argc, char ** argv
{
}

That's really ugly!

Er... yeah. I'm working on a code base where this is used a lot. The phrase "pus-oozing bedsore" is the kindest thing I've had to say about it so far.

Banging on the bits
My spi reads getting no hits
my timing's not tight
something ain't right
this driver is giving me fits
seriously though, my clock signal is *half a bit* behind my MOSI signal using the ESP-IDF, but bang on using the Arduino framework, I think. At least that's what digging around the internet has strongly implied.
I'll know by the 15th when my logic analyzer gets here.
I figured out it was a timing issue because I was getting 0xFFFF back for my pixel reads, but sometimes 0x0000, and when I plotted them in a square I got a zebra pattern.
Unfortunately I may have to rewrite the entire SPI subsystem under the ESP-IDF if I want this stuff to work.
What I don't get is how more people haven't had these problems. I think part of it is nearly everyone uses the Arduino framework except for the hackers, which is unfortunate because the ESP-IDF has a number of advantages. They just need to work the kinks out of it apparently.
I've got a lot of code invested in the ESP-IDF but if I can't get this to work I will have no e-paper/e-ink support in my graphics stuff for it because none of the controllers seem to be able to handle the timing being off by half a bit.

Doesn't that mean you are using wrong SPI Transfer Mode[^]? Configuring a different mode doesn't need any rewrite of ESP-IDF code.

The first 80 are the hardest.
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

Unfortunatley, there isn't an emoticon for this, or I would give it to you.
Nice.
