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.

In Spider Robinson's Callahan's Cross-time Saloon series, he states that the highest accolade for a pun would be to run from the room, screaming, while holding your nose.
Unfortunatley, there isn't an emoticon for this, or I would give it to you.
Nice.

Haha. Thanks for the reminder. A million years ago I saw a comedy skit from the UK set in an airport.
Searching through her bags, the customs officer found a great big bag of white powder.
It's okay though. She'd thoughtfully attached a sticker before packing it.

Can a Vector employee complain about not getting arrays?

I guess that they'd feel pretty list-less about their function being just operating on a string of disappointments.
Maybe he should consult his petite girlfriend, Kathy, oft referred to as allocate.

I didn't know that Brits pronounced arrays the same as arise!
EDIT: It probably works Down Under, though!

...or "arrays" === "a raise" according to this Brit.
- I would love to change the world, but they won’t give me the source code.

That's what I thought. But also that a rise, not a raise, was standard British, in which case the pun wouldn't work as well.

Give em a pointer to arrays and they'll get it.
|

Well, one might ask for some pointers on increasing one's value, or failing that - ask for a reference.
