01 Speaking of microcontrollers, we cannot avoid the 51 series. I remember the first microcontroller I encountered in college was the AT89C51. I believe many people started learning about microcontrollers from here, right? Of course, the AT89C51 is rarely used now. However, another brand of the 51 microcontroller is still very popular, which is the … Read more
