摘要
介绍了液晶显示控制器RA8835的特点,给出了其与MCS-51系列单片机的接口方案,介绍了基于标识符思想的选单程序设计方法,较好地解决了多重选单的切换问题,利用计算机图形学中的Bresenham算法实现直线的显示。经广播发射机测控系统应用表明,这种设计显示效率高,实时性强,系统工作稳定可靠。
In this paper, the characteristics of LCD controller RA8835 are introduced, and the interface scheme between the controller and the MCU is introduced. The menu programming method based on identifier is proposed, which can easily handle problem of switching among multiple menu. Bresenham algorithm in Computer Graphics is used to display line. It＇s shown that the system is reliable and efficiency by using the method in a broadcast transmitter measuring and controlling system.
