What should I do if the power line is too long? How can I improve the anti-interference ability? Should I put it in the middle layer? Should I put a capacitor? Do I need more of both? How do you deal ...
It has been a year since I learned MSP430. I know that if you understand one product, you can basically use all products in this series. But in this society, it is far from enough to just know 430 and...
introduction
In the discharge process of tokamak plasma physics, the study of rupture and sawtooth is of great significance. Rupture and sawtooth exist in most tokamaks. Rupture is a notew...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
The concept of state machine
State machine is an important concept in software programming. More important than this concept is its flexible application. In a clear and efficient program, ther...[Details]
