2、从下到上滚动显示：“江苏大学计算机学院”然后交替显示：“2013年单片机课程设计”“液晶点阵显示屏程序设计”“作者姓名、班级、学号” 2）图片方式：显示相应图片（有左、右移，上下卷等多种动态方式 ）3) 模拟量采样值显示（温度、压力、电位）4) 其它功能不限，可自由发挥（时钟、秒表、计算器、菜单等），拓展要求2、设计思路：将程序分成四个模块：1.主函数模块main.c2.模数转换模块ADC.c 3.液晶显示模块KS0108.c4.测试模块test7279.c其中，在main.c中定义一个功能选择菜单图片，包含课设的简介，图片的变换，模拟量的采集以及计算器的实现，该菜单功能的切换由按键功能来实现

3、。在KS0108.c中定义了两张图片分别来简单介绍一下该课程设计，包含“江苏大学计算机学院、2013年单片机课程设计”和“秦佳、计算机1001、3100602007”；还定义了字符方式下的“液晶点阵显示屏程序设计”；定义了在ADC中要用到的0-9的数字以及计算器中要用到的各种运算符。在其中还定义了上移、下移、左移和右移函数以及计算器实现的函数。在ADC.c中定义了字符形式的“温度压力电位”以及将模拟量转换成数字量的showadc函数。各函数说明三、 程序流程图：a、 系统主流程图b、 主函数流程图初始化各部件c、 显示模块流程图d、 模数转换模块流程图开中断开始显示菜单主函数模块判断键入值并调

4、用相应函数b液晶显示模块模数转换模块a开始判断KS0108是否空闲读取No和模拟量向LCD发送控制命令No=3No=2No=1定义各类显示函数返回压力返回电位返回温度定义初始化LCD函数结束d定义各类图像变换函数以及字符显示函数cd四、 主要的源程序及注释1、main.c#include c8051f020.h #include void Delay1us(unsigned char us)while (us) _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); -us;void SYSCLK_Init (void) int i; / delay coun
