电子线路设计实验报告_李安琪.docx

xian jiaotong university电子线路设计 ii实验报告姓名：李安琪班级：自动化11学号：2110504002日期：2014年4月29日电子线路设计ii实验报告一、 实验内容：1创建一个工程将键盘阵列定义为0. 1. 2- e. f，编程实现键盘设置当前时间，再调用系统时钟，显示在led显示屏上（注意仔细阅读pcf8563资料），键盘设置当前日期显示在lcd显示屏上。2利用d/a转换通道（下行通道）实现锯齿波发生器；输出（15v）固定电压转换成（420ma）电流。3利用a/d转换通道（上行通道）实现数据采集，将采集信号显示在led屏上。程序要求分别具有平均值滤波、中值滤波和滑动滤波功能。二、 实验方法：通过在keil uvision2 中进行程序的编写和语法测试，之后通过电脑usb串口将程序下载到实验板上进行实际的程序运行，通过实际运行结果对程序进行调整。三、 实验程序：本次实验中，我将要验收的三个实验结合分别写了三个程序，我设计了主界面。除第二个程序考虑到要连续输出波形而选定后无法退回主界面外，其与两个程序均能通过按键功能退到主界面。以下为我编写的代码。（1） 日历时钟/-main-/#include #include #include#include#include#define uchar unsigned char#define uint unsigned intsbit be=p16;uchar nian,yue,ri,shi,fen,miao,xingqi,shialarm,fenalarm,flag=1;uchar code table1=20 - - ;
