基于MSP430F227单片机控制的LED点阵书写显示屏设计

以TI公司4单片机为主控制器,以光笔为检测工具,以按键和带字库的12864液晶为辅助设备的LED点阵书写显示屏系统,通过按键的设置可进入到系统的相应功能模式,以光笔可检测在LED点阵屏上接触的位置,从而实现点亮、划亮等功能,并将划亮点的位置用带字库的12864液晶屏同步显示。

Design of LED Lattice Written Screen Controlled by MSP430F227MCU

This design is based on TI Company＇s MSP430F2274 MCU as the main controller,the light pen as the detection tools,and the 12864 liquid crystal with keys and character library as a LED lattice writing display system which is auxiliary equipment.Through setting the key we can access to the corresponding function blocks,and use light pen to detect the position on the LED lattice screen.So that it can realize the function of lighten and draw brightens,at the same time display the positing on the 12864 liquid crystal screen.
