Arduino and Compatible Boards
This document provides an overview of Arduino. (But, now that Qualcomm is involved, I may have to scrap the whole thing. Is Qualcomm going to wreck the platform? Lots of chatter but unclear about what is factual.)

Microcontroller Direct Memory Access (DMA): Architecture, Behavior, and Practical Design Considerations
This document provides a comprehensive, deeply detailed explanation of Direct Memory Access (DMA) in microcontrollers, how it interacts with peripherals, how it differs from PC‑class DMA, and why it is essential for real‑time audio and display systems such as a professional audio diagnostic tool. This is preliminary research that I'm doing. I'm 100% new to this technology, so anything I say here could be wrong!
Teensy 4.1
