"LED display (LED)
"LED display (LED)LED is the abbreviation of LED for short.
it is a display mode by controlling the semiconductor LED.

What is led display for

its general appearance is composed of many usually red LED, and the characters are displayed by the light on and off.
it is used to display text, graphics, images, animation, market, video, etc The display screen of video signal and other information.
the display screen of video signal and other informationLED display screen is also called electronic display screen or floating character screen.
it is composed of LED dot matrix.
text, picture, animation and video can be displayed by red or green light. The content can be changed at any time, and each component is a display device with modular structure.
it is usually composed of a display module, a display module and a display module The display module is composed of a lattice of LED lights.
it is responsible for light-emitting display; The control system can make the screen display text, picture, video and other contents by controlling the lighting of the corresponding area; The power supply system is responsible for converting the input voltage and current into the voltage and current required by the display screen.
the power supply system is responsible for converting the input voltage and current into the voltage and current required by the display screenLED display screen can display changing numbers, words, graphics and images; It can be used not only in indoor environment but also in outdoor environment.
it has incomparable advantages over projector, TV wall and LCD screen.
it can be used in outdoor environmentLED has been widely valued and developed rapidly.
it is inseparable from its own advantages.
these advantages are summarized as follows: low operating voltage, low power consumption, miniaturization, long service life, shock resistance and stable performance, and the development prospect of LED is extremely broad.
at present, LED is moving towards higher brightness, higher weather resistance, higher luminous density, higher energy consumption, higher energy consumption, higher energy consumption, higher energy consumption and higher energy consumption The development of higher uniformity, reliability and panchromatism.

Most of the control cards with dialing code were used in 2006-2008.
at that time, most of them used serial port communication, and the dialing switch was used to control the baud rate of the card, which affected the distance of the serial line when the serial communication was carried out.
at present, there are few dialing switches in the control cards.
it can be set through the software.
.
in this paper, the dialing switch is used to control the setting of the baud rate of the card
