I want to do 1024-point AD sampling (not done in an interrupt), and then perform FFT on it, and display the frequency corresponding to the point with the maximum amplitude, but the data output cannot ...
[size=9pt][font=宋体]We have blocked our CD-ROM drive, floppy drive, and USB interface, but how come the customer information is still transmitted? [/font][/size] [size=9pt][font=宋体]Urgent, the boss is ...
I want to ask the experts, I want to use a sensor to measure the height of an object (such as a cup, kettle, etc.), the requirement is not limited by the object, of course the height will have a range...
It has been about a year since I started to learn about the 430 microcontroller. At first, due to limited conditions, I just borrowed books from the school library. After studying for about a month, I...
I wrote a driver for a USB device. Every time the device is inserted, a series of configurations need to be done at the UI layer before it can start working. If Coinstaller is used, it will only work ...
1. SummaryA new module called TrigonometricMath Unit (TMU) has been added to TI's newer TMS320F28x7x. TMU is a hardware accelerator developed by TI for mathematical operations such as trigonometric fu...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();

Solar street lights are mainly composed of four parts: solar photovoltaic cell components, batteries, charge and discharge controllers, and lighting fixtures. The bo...[Details]
introduction
For the voltage regulator modules (VRMs) that power the latest computer central processing units (CPUs), power supply designers have historically used multiphase interleaved b...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
Toyohashi University of Technology demonstrated electric field coupled wireless power supply technology using life-size car tires and roads at the wireless technology exhibition "Wireless Technolog...[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]
Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]
Continuity test
A variety of devices need to be checked for continuity, including cable assemblies, printed circuit boards, and connectors to ensure that these components have the expected contin...[Details]
1. When the slip speed regulating motor is undergoing frequency conversion and energy saving transformation, the original excitation box (referred to as the speed regulating box) and the original s...[Details]
At present, how various communication technologies will evolve after 3G is a focus of great concern in the industry. Especially for TD-SCDMA, whether it can achieve smooth evolution to the next gen...[Details]
In order to prevent the lithium battery from being damaged by abnormal conditions such as overcharge, over discharge, and overcurrent, a lithium battery protection device is usually used to prevent...[Details]
The installation locations of DC-DC converters are relatively scattered. DC-DC converters can be found on the power board, main board, logic control board and other circuit boards of PDP color TVs....[Details]
