I thought I'd killed 2 ESP32-S3 boards yesterday but couldn't fathom how. They both just stopped appearing in the Arduino IDE dropdown, as if they weren't plugged in. Found a post saying press boot as you plug them in or reset then boot if that fails. After a couple of tries it worked. Still have no idea what I did to causd the issue in first place which is frustrating. At least they're working again now. #esp32 #arduino #microcontrollers

If you've ever wrestled with fixed-point math, scaling, and rounding, this blog post is for you!

I go deeper into binary arithmetic, division tricks, rounding, and what it really takes to build fixed-point systems that work.

As always, I appreciate all of your feedback and corrections.
