That's helpful; thanks. I guess coming from much more of a software background, having the ability to write C code (which feels like an acceptable veneer over the hardware to me and works well across chips) and having programmatic access to the pins feels pretty empowering and all-encompassing. However, it does make sense to me that someone coming from a hardware-first view of the world would feel those barriers to direct hardware access much more acutely and recognize the limitations that I don't.

I appreciate the thoughtful and detailed response.
