为了实现多彩LED点阵显示屏系统设计,利用PC机将汉字或数字转换成点阵显示数据,通过串行口发送给单片机,单片机利用接收到的数据控制多彩LED点阵显示屏.同时,系统利用74HC595移位寄存器,实现了对汉字或数字移动控制.设计方案克服了原来固定显示、单一颜色、电脑控制的缺点,通过通讯模块实现显示内容的实时更改.

To realize the design of multicolor LED lattice display system,Chinese characters or numbers are transformed into lattice display data by PC and sent to single chip micro computer.Then single chip microcomputer controls multicolor LED lattice display using data received.Meanwhile,the system realizes mobile control of Chinese characters or numbers by 74HC595 shift register.The design scheme overcomes the shortages such as fixed display,single color and computer control,and realizes real-time modification to display contents through communication module.
