I always love to solve new problems.
Today I realized I could use the hardware DMA capabilities of the I2S hardware on an ESP32 to drive 8 pins of data simultaneously w/ background transfers.
The upshot is I can drive an LCD connected via an 8-bit parallel bus - at least in theory - and do DMA transfers with it.
But nobody has implemented it yet to drive an LCD display, meaning I get first crack at it.
There's an e-paper display that uses it, but it doesn't drive a controller chip - it drives the display panel directly with 14 pins or so, and that's a total one off. It's what gave me the idea though.
The point is, in IoT land there are *new problems* - in a larger field where it seems like everything has been done before, and done to death.
I love it.

Dumb question maybe, but are you doing all this for professional purposes, or is it only a side hobby of yours ?
|

Kind of in-between.
GFX is a library I use for my professional projects, but I developed it on my own time and released it to the community.
The display drivers that bind to it are primarily for the community, because I don't need most of them for my own projects. This falls under that (for now) though I may use it professionally down the line.
So it's to support my larger endeavor, which supports my professional and hobbyist pursuits.

...other than Espressif, the makers of the ESP32 chip. There's a documented API[^] and a code example[^]. They call the 8-bit parallel bus driven by I2S hardware "i80 interface".

Fair enough. I must have missed that project.

Nice!
I used to love getting the maximum out of CPUs and lesser devices back in the day. For better or worse, my career went in a different direction, and I don't have as much time to play around with hardware as I'd like.

Congratulations, that should speed up things considerably.
It's interesting, all the Embedded code I've looked at very few seem to use DMA.

In my experience a lot of embedded developers aren't programmers and are quite scared of callbacks, function pointers and everything that is mildly complex to code.
I often have to explain basic concepts like pointers and double pointers to coworkers.

Yep and it takes effort to learn and apply.

You are having fun. I agree with your description of IoT land. I also think security is a big area in IoT land that needs constant attention. AI could be the big player there, as well, both in management and security.

Hahaha. How about JSON parsing on an 8-bit CPU?

Did you see the article on the MIT development of paper-thin speakers? Hoodie and hat inserts come to mind - I'm thinking for people with sound sensitivity in particular.

That sounds amazing! (forgive the pun *ducks*)

I really miss working in IOT, I haven't touched any of my home projects in a couple years now, no longer work at somewhere that has a use for IOT. I'm afraid some of my skill set is fading.
I work for a medium sized community college building software for them now, pay is good, benefits are excellent, the retirement package is over the top, and the work is absolutely boring.
I feel like embedded work is much more interesting: pore over the datasheets, choose the correct chips for the job, master you're C skills, and enjoy the pain of getting an inert object to light up and do something. now with web development you spend most of the time looking up what the frameworks do as they change every year, what framework, what platform. you can never master this crap, it changes too quickly.
