液晶控制芯片SED1335的控制程序

// CEEBACK.GAO. 2006-05-09
// 目标器件: LCM: AG_320240,SED1335  
//			 MCU: STC89C58RD+
// 实现功能: 可以写 ASCII 码字符,写汉字(文本层,图形层)
//			 画直线,画圆;
// 说明：对320*240点阵屏幕坐标定位如下
//		 左上角为原点(0,0),水平向右为X轴正方向,垂直向下为Y轴正方向
//		 X 轴坐标取值范围: 0~319;
//		 Y 轴坐标取值范围: 0~239;
// 字模提取方法：采zimo221软件,纵向取模,再修改图像->旋转90度->图像上下调换。
//				 这样依次得到左上部, 左下部, 右上部和右下部四部分分配代码

// 文本方式下的汉字显示方法
/*在文本方式下显示汉字, 需要在SED1335 等显示RAM 内建立一个自定义字符库
 CGRAM,然后通过在相应的单元写入相应的字符代码来实现汉字的显示.
 SED1335 等的字符代码对应的是8x8 点阵的字符块, 而一个汉字需要四个8x8
 点阵的字符块组合显示, 所以在建立汉字的CGRAM 时, 需要四个字符代码管理一个
 汉字, 一般是按左上部, 左下部, 右上部和右下部四部分分配代码. 比如在演示程
 序中建立 "清华" 两个汉字的CGRAM,那么这两个汉字的代码为80H(81H,82H,83H)和
 84H(85H,86H,87H).*/
