针对连续画“点”法实现LCD表格显示效率较低的缺点,提出用“按字节赋值”的方法来提高表格显示的效率。然后以SED1335为例,具体说明了应用该方法来实现画一条垂直线和画一条水平线这两个关键子程序的设计与实现程序。
For continuous painting “dot” method to achieve the LCD display efficiency of the lower the shortcomings of the proposed “By byte assignment ” method to improve the efficiency of the form display. Then, taking SED1335 as an example, the paper illustrates the design and implementation of two key subroutines of drawing a vertical line and drawing a horizontal line using this method.
