Chances are, if you found this site then you already know what a microcontroller is. But you might also be here to educate yourself, in which case you should read this post to get a very brief introduction. Fair warning : this post contains a lot of TLA, Three-Letter Acronyms. This section contains compendiums covering every aspect of using microcontrollers, both hardware and software. I’m mostly interested in STM32 microcontrollers, but not exclusively. And if you’re expecting Arduino, expect again. As with everything on this site (and as Ryan Reynolds would say), I’m only dealing with the pro shit.
