I have a TMS320F2812 BGA package chip and want to draw a minimum system board. It should have a crystal oscillator circuit, a reset circuit, a power supply circuit, and a JTAG circuit. [[i] This post ...
I want to collect 8-bit data from the external device. What sensor can I use to receive 8-bit data? Can DS18B20 be used? Both serial and parallel data are acceptable....
Designers may design an odd-numbered printed circuit board (PCB). If routing requires an extra layer, why use it? Wouldn't reducing the number of layers make the board thinner? Wouldn't it cost less i...
Today a colleague brought a video player to me and said it would not turn on. After checking, I found that the backlight was not on. The MCU used is STM8S_48P. Pin 21 is the backlight enable control. ...
Some DCDC chip technical manuals directly state the maximum duty cycle that can be output, while others do not. Where can I find it in the technical documentation?...
Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]
TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is one of the three major standards for the third generation of mobile communications. It is a communication standard with indepen...[Details]
Although improper medical device product design is not always associated with medical device-related errors. Studies of users have shown that lack of adequate training accounts for 70% to 90% of suc...[Details]
Digital signal processors have efficient numerical computing capabilities and can provide a good development environment, while programmable logic devices have highly flexible configurability. This...[Details]
For more than 10 years, analog-to-digital converters (ADCs) have been widely used in industrial process control, medical instruments, communication systems, radar and other products as a booster of in...[Details]
Overview
Bioelectric signals are very weak, and there is strong interference when detecting them. Therefore, there are many technical difficulties in designing high-quality bioelectric ampli...[Details]
With the development of automatic control technology, the application of precision air pressure generation and control technology is becoming more and more extensive. However, the traditional valve...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m~1kHz), audio (20Hz~20kHz), video (20kHz~10MHz), radio fre...[Details]
In view of the problems in the actual FPGA development process, such as difficulty in locating faults, long compilation time after repeated code modification, and inability to confirm fault solutio...[Details]
Some application designs have higher requirements on the speed at which the system's switching power supply can provide voltage output. Figure

In the issue of ensuring the safety of drivers and pedestrians, the proportion of electronic technology has increased. According to the survey, 80% to 90% of traffic accidents are caused by driver...[Details]
1. What is fading?
In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]
1 Introduction
Generally, when transmitting information over short distances through electrical signals, baseband signals can be directly transmitted. However, over long distances, baseban...[Details]
Power semiconductors and reactive components (capacitors and inductors) are ubiquitous in today's electrical equipment. In normal operation, they can cause two undesirable side effects on the AC line ...[Details]
A correct circuit design cannot be manufactured 100% correctly when it is taken to the factory for manufacturing. It will always be affected by various uncertainties, such as deviations in manufact...[Details]
