The LED multi?function display is presented,which adopts the dynamic scanning method,takes STC89C58RD+MCU as core chip and uses the self?made infrared remote controller to download the informtion to the host computer. The LED display screen is composed of 1024 red?light diode array(16 * 64 dot matrix). One 74HC154 decoder chip is used in the row scanning circuit. Eight 74HC595 chips are used in column scanning circuit. An integrated infrared transceiver is used in the in?frared remote controller. The system can not only display numbers,letters,Chinese characters and other dynamic and static sta?tus information,and communicate with PC through the serial port to update the displayed information,but also update the dis?played contents and move the display information in four directions by the remote controlled keyboard.
