Today, some students are worried that connecting a microcontroller development board to a computer via a USB cable might accidentally burn the computer. After all, a computer is much more expensive than a microcontroller. Today, let’s discuss this issue. 1. Why is it generally safe and unlikely to burn the computer? Currently, the most common … Read more
The AT89C2051 is a streamlined version of the 51 microcontroller, omitting the P0 and P2 ports, and featuring only 20 pins. However, it integrates a very useful analog comparator, making it particularly suitable for developing simplified 51 application systems. After all, when developing simple products, we often do not need all 32 I/O ports, making … Read more
