[size=4]Impedance matching is a common concept in high-frequency design. This article provides a relatively good analysis of this "impedance matching". It answers what impedance matching is. Impedance...
There are two types of head installation: C type and CS type. Both have 1 inch 32 threads and a diameter of 1 inch. The difference is the distance between the lens and the CCD target surface. The dist...
I upgraded the BSP from 4.2 to 5.0. After the CPU goes to sleep (about 20ma current), if it sleeps for dozens of seconds and then wakes up, there is no problem. If it wakes up after sleeping for one m...
I've been debugging a color screen these days. Haha, now that it's done, I'll play whack-a-mole. Hehe! Every time the score increases by 100, the speed will increase by one level. Color screen resolut...

My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
The data collector of the automatic weather station is generally designed based on a single-chip microcomputer or a PC/104 bus controller. It has the characteristics of good compatibility with PC, low...[Details]
I. Introduction
Since RS232 has a short communication distance (only 15 meters according to EAT/TAI-232 standard), and can only perform point-to-point communication, it cannot directly f...[Details]
In the analysis of electronic circuits, static analysis (also known as DC analysis) is the basis of circuit analysis. However, it is well known that electronic components are nonlinear, so the anal...[Details]
RS-422 and RS-485 are both serial data interface standards, which were developed and published by the Electronic Industries Association (EIA). RS-422 defines a balanced communication interface with a ...[Details]
Digital array radar (DAR) uses digital beam forming (DBF) in both receiving and transmitting modes to achieve flexible distribution and reception of RF signal power in the airspace, obtain excellent t...[Details]
