摘要
内置中文字库的点阵液晶显示驱动器RA8806具有极强的通用性。RA8806集成的8×8的键盘扫描接口和4线电阻式触摸屏控制接口为人机交互界面提供了理想的解决方案。给出了RA8806详细的硬件配置方法和相关程序。实验结果表明,RA8806构成的人机交互系统的硬件电路更加紧凑、可靠,软件设计更加方便。
RA8806 is a dot-matrix LCD driver with built-in a Chinese character font is stornger Universality.RA8806 provides an ideal solution for human-computer interaction by integrating 8×8 key-scan circuit and four-line resister type touch panel controller.Configuration method for hardware and related control subroutine are given in this paper.The results show that the system hardware circuit is more compact and reliable and the software design is more is convenient which the human-computer interaction system is constructed by RA8806.
