基于ADC0832和LCD160128设计的数字电压表

作者 张小波

液晶显示模块主要用来实时显示电压值、固定字符和汉字。根据LCD160128液晶显示器技术资料可知，在编制C代码时，我们把程序分为两部分：LCD_160128.C源文件和LCD_160128.H头文件。在LCD_160128.C源文件定义了一些函数，其中最主要的函数是Display_Str_at_xy(uchar x,uchar y,uchar *fmt)。其具体代码参加附录程序。另外，显示的汉字必须用字模软件取得该汉字的字模。 ☆ 课堂小结

本节课我们主要学习了如何应用ADC0832和LCD160128设计一个数字电压表。知道了在硬件上ADC0832芯片和单片机的连接，在软件方面，我们着重介绍了介绍了LCD160128液晶芯片的有关技术资料和具体用法，重点分析了LCD160128.C源程序的设计。 ☆ 完整程序代码
