Today I officially started debugging this board. It took me half a day to disassemble many boards and finally finished soldering this PCB. Let's get back to the point. Let's do the simplest experiment...
There are about 30 MCUs, each of which needs to send about 10 bytes of information to the host computer every 30ms. What is the appropriate baud rate for the MCU? (The host computer query method) Than...
As shown in the figure:There is still the possibility of high-frequency transient interference in actual application environments. Generally, high-amplitude transient interference will be generated du...

Automotive applications are particularly sensitive to EMI events, which are unavoidable in a noisy electrical environment consisting of a central battery, bundled wiring harnesses, various inductiv...[Details]
In order to highlight the concept of "energy saving and environmental protection" of intelligent buildings, solar street lights are designed for intelligent communities. The inclination and capacit...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[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]
Motors are important products that convert electrical energy into mechanical energy to achieve automation, and they are widely used in industrial control, medical electronics, white a...[Details]
Introduction
Nowadays, people pay more and more attention to the security alarm system, and people have higher and higher requirements for the functions and performance of the alarm. This paper prop...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
Power supply is often the most easily overlooked link in the circuit design process. In fact, as an excellent design, power supply design should be very important, which greatly affects the perfor...[Details]
DigRF
is
poised to replace the two main forms of data communication paths between RF and baseband semiconductor devices:
analog
signaling, and proprietary digital signaling (paralle...[Details]
The biggest advantage of Profibus is that it is guaranteed by the stable international standard EN50170 and has been proven to be universal in practical applications. It has been widely used in man...[Details]
The programmable controller directly controls the stepper motor, which can significantly reduce the cost of the control system of the modular machine tool automatic production line. The article int...[Details]
In recent years, the application of single-chip microcomputer systems in the field of industrial measurement and control has become more and more extensive. However, for industrial sites with harsh...[Details]
Current sensing in automotive applications includes controlling the current through solenoids and injectors. For example, during diesel injection, we rapidly increase the current to the induction i...[Details]
