Both thermocouples and thermal resistors are contact temperature measurement. Although they have the same function of measuring the temperature of an object, their principles and characteristics are d
When hardware engineers first come into contact with multi-layer PCBs, it is easy to feel dizzy. There are often ten or eight layers, and the circuits are like spider webs.Draw several diagrams of the
When the microcontroller is powered off, all data in the RAM data area will be lost. For example, if you use an MP3 player and start playing from the first song every time you restart it, after a few
Abstract: The power angle measurement data acquisition card introduced is a PCI bus interface card implemented by the Cygnal C8051F021 single-chip microcomputer. The card uses two dual-port RAMs to ex
[size=4]The sound card obtains the sound analog signal from the microphone, and converts the sound wave amplitude signal into a series of digital signals through the analog-to-digital converter (ADC),
LCD TV system based on DVP-M IntroductionWith the development of digital technology, LCD TV (liquid crystal television) related technologies have also made rapid progress. This article takes the LCD T
