Beginners start with the development board + marquee. Although the program was successfully run, I was still confused;
in this album, starting from 0, the common hardware peripheral to the microcontroller is classified, analyzed, and physically tested.
It allows everyone to see how the microcontroller drives each piece of hardware, what the driving principle is, and what the driving conditions are.
Although it cannot make everyone proficient in hardware, it can give everyone an idea and know in which category to choose the model. As for having no clue.
