Geek, dad, pilot, sailor. Once hand-assembled a Space Invaders game for an Ohio Superboard II.
Just FYI and in case you didn't know - if your MCU has an I2S peripheral which supports PDM, you can use the data line in exactly the way you've just described.

I think it's been completely repurposed. Thank you for your attention to this matter!

When was this? I had PCBs with ESP32-MINIs on arrive from the same place at the end of last week; I do so fairly regularly, and X-raying the things has never been part of the process..

Frankly, I think we'd all get along better if people spent as much time on prompt engineering for their human interactions as they do for when they're talking to a glorified guess-the-next-word engine..

Can you nip over here next time I've got to go to a "difficult meeting"?

As Mike's brother, I echo his sentiments with the rider that Jamal was, in my opinion, by far the least unlikeable of the characters in the courtroom. In the same way as it's hard to dislike a broom.

Thank you. Exactly what I needed this morning.

My cat knows where the feed server - I mean servant - is. It's me.

There was a certain beautiful simplicity about talking directly to the microprocessor in the context of a system that was simple enough that one person could understand the entire thing.

Maybe that's why I'm still spending a lot of my time writing code for embedded systems...

Yes, for an entire Space Invaders game for an Ohio Superboard II back in the day.

I'm more an NT 3.51 person myself. But here's some fantastic Limassol street art:

Names my cat responds to:
- when hungry: anything;
- when not hungry: nothing.

She's got one eye slightly open with that "I doubly double dare you" thing they do.

Been there, done that, here's a cat for you.

I'm really sorry.
