To add to this, most micros these days are ARM based which are specifically designed to not need assembly in their boot code. I basically never use it anymore.

To add to this, most micros these days are ARM based which are specifically designed to not need assembly in their boot code. I basically never use it anymore. That said, you should have some understanding of what C code will map to what assembly for the purposes of memory management and performance. Also: to say its a calling is accurate. I love what I do because what I create is physical and interacts with the physical world. I can hold my projects in my hands and say "I made this". I've done web and desktop stuff and can say that this work is significantly more fulfilling to me.
