摘要
LED多功能显示屏系统采用动态扫描的方法,以STC89C58RD+单片机作为主控芯片,利用自制的红外遥控器无线下载信息到主机显示。显示屏由1 024只高亮发红光二极管构成的16×64点阵组成,行扫描电路采用74HC154译码器芯片驱动,列扫描电路用8块74HC595驱动,红外遥控发射头采用一体化红外收发器。系统实现数字、字母、汉字等信息的动静态显示,和PC机串口通信来更新显示信息,系统还可通过遥控器键盘远距离进行信息的上下左右移动及显示内容的更新。
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.
