| 摘 要： | 由单片机控制彩色液晶显示器实现动态曲线显示是一项重要的应用技术,如何利用采样数据实时绘制动态曲线,是很多智能仪器设计的关键。介绍采用YD-501A彩色液晶显示器与MCS-51单片机实现实时动态曲线显示的方法。实践证明该方法图形处理速度快,可以快速实现曲线的实时动态显示,多层图形的显示也可以通过刷新行数据的拟和来实现。

| Abstract: | It is an important application technique that the dynamic graphs are displayed by the color LCD controlled by MCS -51 Single - chip. And the real - time display of dynamic curve resulted from the acquired data is a key technique in the intelligent instrument designing. The interface is introduced between the YD -501 color LCD and MCS -51 Single -chip and display principle, and the technique of dynamic graph display, and an example programmed by the assembly language. Test results showed that way deal with graph rapidly, and may implement real - time dynamic display of curve. The multi - layered graph also can be implemented by refreshing the row data. |
