I'm currently really interested in #microcontrollers and #electronics especially on how to design cpu s or how they work internally but man my electronic skill isn't that great even though i had 5 years electronics. But now i'm getting older and regret not having paid that much attention to it. So my question is how could i start and what should i get to get of the ground. Like breadboard stm32 controller ... and what kind of books can you recomend to get me into it.
