15.6 液晶图形显示实例
点阵图形型液晶显示模块除了可以显示中文信息外,另一个优势是可以显示图形。因此,下面就介绍如何提取自定义图形的点阵信息以及图形的显示。
15.6.1 图形数组的提取
这里介绍的均为单色液晶,只能显示黑白图形,因此需要首先将图片转化为黑白图,如图15.34所示。图形的点阵信息可以逐个查看像素点的黑白值。为了更快地得到图像的点阵信息、得到任何一个图形的点阵信息,用户可以选择一款字模提取程序,从中打开黑白图像即可,如图15.35所示。

用字模提取程序得到的点阵信息如下所示。

将该点阵数据存为一个数组便可以在程序中使用,示例如下。
char code Tu[45][16]=//图形数组,蝴蝶图案
{
//上述点阵数据
}
