The effect of installing it on my headphone amplifier: (The machine cannot be covered; the green PCB below is also an additional one, input switching circuit.)The board was made when the 5 yuan proofi...
I use a matrix keyboard to input a two-digit decimal number. How can I convert it into binary and input it into the FPGA? For example, 23 becomes 0001 0111. Note that it is not converted into BCD code...
Yesterday, @lb8820265, who had not appeared in the forum for a long time, was all over the screen~ He brought his "Wanli" car back to the forum. He is looking forward to friends who like it to play wi...
When I use CAN communication and PC communication, the DSP count only sends 10000 data, but the CAN card receives 10010 data. Later, I found that there are duplicate data and the DSP resents. What's g...
A 8086 program performs multiplication of two 32-bit numbers. I am confused because I have just started learning it. The program is as follows: data segment mulnum dw 0000,0fffh,0000,offfh,4dup(?) dat...
As shown in Figure 1, I know how to calculate RC filtering. I know the frequency of the square wave and the three RC constants reach full amplitude. The filtering effect is a bit like a dorsal fin sha...
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]
1. Overview
Will passive devices
produce nonlinear intermodulation distortion? The answer is yes! Although there is no systematic theoretical analysis, it has been found in engineerin...[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]

I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[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]
This paper establishes a fuel cell engine test platform based on the NI integrated hardware and software environment. This platform can realize the test and control of fuel cell engines and their a...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
Editor's note: In order to help technicians or engineers who have knowledge of PIC microcontroller assembly language quickly master the method of using C language to program PIC microcontrollers, t...[Details]
In recent years, with the rapid development of the information industry, dot matrix LED display screens have been widely used in various advertising and information display systems such as the fina...[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]
At very low temperatures, certain metals and alloys lose their resistance to electric
current
and become
superconductors
. Two parameters that are often measured are the transition ...[Details]
Today, the value of electronic components in cars accounts for 15-20% of the total vehicle. In the future, this proportion may be as high as 30-40% as more safety electronics, fuel consumption and ...[Details]
