/*软件名称：智能涡轮流量计 *
* *
*作者：李维平&陈超 *
*时间：星期二 2005年4月26日 *
* 晶振：640KHZ *
* 微处理器：PIC16F877或者PIC16F877A *
* 采用澳大利亚HI-TECH公司的PICC编译器 * * 功能简介： *
*可显示瞬时流量和累计流量 *
*累计量定时存储于EEPROM *
*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） *
*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 *
*当第一点K值为0时，可以作为频率计使用 *
*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 *
*按键操作采用中断方式 *
*仪表系数K默认小数部分为零 *
* *
