摘要:
设计发光二极光管(LED)点阵电子显示屏控制系统.系统中的控制电路采用AT89C52单片机,片内8 K的Flash ROM作为程序存储器,为了便于升级,外部又扩展了一片程序存储器(27256),可以对程序进行扩展和加密保护.使用Flash存储器保存显示数据,数据更新方便,系统掉电后数据不丢失.显示内容经过屏幕编辑机的编辑,通过RS232/RS485串行口将数据送入单片机显示系统的随机存取存储器(RAM)中,再由单片机显示系统驱动,LED达到显示图形或文字的效果.
Abstract:
The control system for lattice display screen with light emitting diode(LED) has been designed.The single chip microcomputer named as AT89C52 is used in the control circuitry.Inside of the AT89C52,there′s a Flash ROM used as program storage,the memory of which is 8 K.A piece of ROM named as 27256 which can expand and protect the program using password is added outside in order to improve the display.It is convenient to update the data using the Flash ROM to store them and the data won′t disappear even if a sudden situation such as power failure is encountered.Moreover,what is shown in the electronic display screen can be edited by the screen editor,the result of which is transported to the RAM of the display system of the single chip microcomputer through the RS232/PR485 interface and driven by the display system so that the LED could display the words or pictures.
