1: /*软件名称：智能涡轮流量计 *
2: * *
3: *作者：李维平&陈超 *
4: *时间：星期二 2005年4月26日 *
5: * 晶振：640KHZ *
6: * 微处理器：PIC16F877或者PIC16F877A *
7: * 采用澳大利亚HI-TECH公司的PICC编译器 * * 功能简介： *
8: *可显示瞬时流量和累计流量 *
9: *累计量定时存储于EEPROM *
10: *瞬时量和累计量都可实现精度自动调整（小数点动态移动显示） *
11: *仪表系数K可以在线置入EEPROM当中，设置同时计量工作仍继续 *
12: *当第一点K值为0时，可以作为频率计使用 *
13: *仪表系数的点数可通过修改宏定义中的set 值来改变，范围3～6点 *
14: *按键操作采用中断方式 *
15: *仪表系数K默认小数部分为零 *
