出租车运行方向指示器研究
Research on Taxi running direction indicator
本文介绍了一款基于MCU的LED点阵出租车运行方向指示系统。该系统可实现中英文字符静态及动态显示，并且能够使用通用键盘控制，也可以通过级联的方式扩大显示屏幕的尺寸以达到增加显示内容目的。显示内容由上位机生成，通过串口传送给控制器并存储。方案基于MCU设计性价比较高，因此，该系统可以在会议牌、医院叫号等诸多面得以应用。
his paper introduces a display system of TAXI with LED lattice board that based on MCU. The system can realizes static and dynamic display, what is more, it can easily changes contents of the display according to use num lock, And can be cascaded to expand the screen size to achieve increased content purposes. The content can be generated by software, and can be transmit to MCU via serial port. Because of the cost-effective of using MCU, this display system is extensive used to the meeting brand, station to station in hospital and so on.
