2 程序名称:智能电表主控程序
3 程序设计:freevanx、LDZ
4 时间:2006-9-29
5 功能: 1、计算电量、电费
6 2、接受键盘输入,将所要求的信息显示在LCD上
7 3、通过键盘设置内部计费参照,适应不同种类的器材,不同的
8 地区,不同的电价,不同的计费时段。

11
12 编译方法:将main.c
13 characterlib.h
14 C51FPS.LIB
15 STARTUP.A51(不是必需文件)
16 添加到同一Group,然后
17
18 1、在工程文件列表中的main.c文件上右击鼠标
19 2、选择Options for file “main.c”,打开一个对话框,
20 3、在Properties选项卡的右边激活 Generate Assembler SRC file 复选框
21 4、在同一位置激活 Assemble SRC file. 复选框
