单片机控制工作液晶显示器
点击浏览该文件我们的产品是智能液晶终端，是采用全新工规液晶屏，然后加上我们自己的液晶驱动，包括汉字库，界面图片数据储存FLASH，可以集成触摸屏（有漂移补偿技术）、键盘和时钟等。您只要通过简单的RS232串口或打印机并口接上你的设备
详细功能:
1. 在指定的X轴，Y轴的位置显示16X16或32X32的中英文字符，内置有中英文字库。 （加装64M的NandFlash可支持24X24,48X48,64X64的中英文字符）。
2. 在指定的X轴，Y轴的位置显示直线，圆或椭圆。
3. 显示预置的位图（用PC机预先下载到控制板的图片，支持的图片有256色位图和JPG图，JPG图片在VTer_8060TFT_080的实际显示效果是64K色）
4. 清除全屏或清除指定位置和长宽的矩形。
5. 自动显示实时时钟（可关闭，可指定位置和显示方式）。
6. 所有的功能均可通过单片机的并行口或RS232串行口发送简单的指令完成。
