I recently used MP2459. The datasheet says that the enable pin pull-up is effective. I want to ask what is the role of R4 in the example it gives? Can it be directly connected to R5100k? What is the d...
I feel that analog IC design should be to design analog circuits, design op amps, etc., and then build TTL, CMOS, etc. on silicon wafers to make IC chips; but I often see that IC design is to design I...
Main Agenda of the Seminar
1. Provide a detailed introduction to the definition and classification, system considerations, and module analysis of industrial robots;
2. Count the challenges faced in in...
I have been using the LaunchPad G2553 board to write the LCD12864 display driver in 8-bit parallel mode. Now the functions are almost sufficient, so I want to expand some functions, but I find that th...
I want to use serial control for some chips. Can I use vcc and gnd to control them? The signal lines are connected in parallel. I use vcc and gnd to control whether they are connected or not. I think ...
Obtaining real-time and reliable traffic information has always been a bottleneck problem in the development of intelligent transportation systems. The establishment of an intelligent transportatio...[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]
From the moment AVS video was born, scientists and engineers have been working tirelessly to reduce the size of audio and video bitstreams. Various advanced video compression algorithms have emerge...[Details]
With the rapid development of network technology and information communication, network economy and knowledge economy are no longer the exclusive domains of IT and other high-tech industries. The i...[Details]
The discipline of HHCE (Home Health Care Engineering) is gradually entering people's lives as people pay more attention to health and telemedicine develops. It advocates the concept of "seeking m...[Details]
In the WTK22wtklibdevicesDefaultColorPhoneDefaultColorPhone.properties file in the WTK directory, there is a line touch_screen=false. Change it to true.

Nowadays, the phenomenon of using cloned taxis and trucks for operation is becoming more and more serious. The so-called cloned car is one or several unlicensed vehicles that are used to copy anoth...[Details]
For mobile phone products, using low-cost components in design is only the first step to make the price competitive. The cost of the production process, especially the cost incurred during the fina...[Details]
1.AVI
The full name in English is: Audio Video Interleaved. People are very familiar with the AVI format, which is also very common in daily life, and the video quality is also very good. ...[Details]
The automated management and operation system has become an indispensable part of modern enterprises. The video image transmission monitoring system has been widely used in important occasions such...[Details]
The dual-field-of-view infrared optical system can simultaneously provide two images with different magnifications and fields of view. The large field of view in the system has a lower resolution a...[Details]
In view of the fact that a single ordinary type of fire detection alarm can no longer meet the demand, the use of multiple sensors to comprehensively collect various abnormal information before a f...[Details]
With the development of mobile computing technology and wireless communication technology, micro mobile terminal devices are increasingly used in the fields of mobile data collection, transmission,...[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 (parallel or serial) for...[Details]
