A few days ago, I locked the JTAG of an 811. Now I have replaced it with a new one. Then I referred to the information on the Internet and made a JTAG anti-lock program, but I don’t know if it is corr...
Due to customer development needs, we need to find an optical fingerprint acquisition module with a data format that complies with ISO19794-2 FMR-20. However, after searching the market, we found that...
I want to use opengl es to draw the interface recently, but I use a qnx virtual machine, so the call to eglGetDisplay always fails, and the print message says that the nvidia driver file is missing. I...
I think you can do this, but it will take a lot of time. 1. Learn some basic knowledge by yourself. For analog circuits, you need to read books by RAZAVI and PRGRAY. For analog systems, you can read b...
[color=#000][font=Arial][size=14px]RT Because many people asked me, I put this kind of non-privacy function part on the blog, hoping that people with doubts can see it [/size][/font][/color] [color=#0...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]
introduction
Throughout the history of automotive lighting, power has always played an important role. Initially, cars only needed headlights to see the road in the dark. Later, other light so...[Details]
The Portable Digital Data Acquisition System (PDDAS) uses LabVIEW Real-Time and PXI to control the wind tunnel test and record air pressure data from 128 different channels.
"The LabVIEW Real-...[Details]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
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]
Instrument stepper motor
The stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non...[Details]
Smart lighting control systems provide high controllability for various buildings and further enhance the level of green energy. They are the core products of energy conservation and digital techn...[Details]
With the continuous consumption of earth's energy and the scarcity of resources, the harm of greenhouse effect to human beings, and the serious pollution of the atmosphere to the earth, the intern...[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]
The traditional display screen using 51 single-chip microcomputer to control LED dot matrix has relatively simple functions. If it is to achieve diversified functions, it often takes a lot of time ...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
