How should ADC select the sampling rate?
How do you choose the sampling rate when using AD?Assuming that the bandwidth of the band-limited signal is f0, the sampling rate of the ADC we choose must be greater than 2xf0.But are there other con

[align=left][color=#000]In the first step, I replaced the original slope generator with the value of the motor encoder, and used the first step to make a closed-loop system, with only anti-PARK and SV
A newbie is looking for a schematic diagram and program for a single-chip microcomputer to control 10 RGB light-emitting diodes
I am a newcomer and am currently working on a graduation project. I don't study well in my studies, so I would like to ask for a schematic diagram and program for using a single-chip microcomputer to
Things to note about ARM programming
1. ARM is a 32-bit processor. Normally, if there is no special requirement, the structure in C language requires 4-byte alignment. 2. In the actual code, there are two problems: a. It requires multipl
What should I pay attention to when assembling a desktop computer by myself?
[i=s]This post was last edited by wugx on 2016-5-26 17:54[/i] My laptop has been slowing down recently, so I want to buy a desktop. I looked online and found that the price of the same desktop compute
SPI driver issues
This is my first time to use SPI, so I have some basic questions. Let me first introduce the S3C6410 chip I use. Here are a few questions, and I hope those who know the answer can answer them patientl
