/*軟件名稱：智能渦輪流量計 *
* *
*作者：李維平&陳超 *
*時間：星期二 2005年4月26日 *
* 晶振：640KHZ *
* 微處理器：PIC16F877或者PIC16F877A *
* 采用澳大利亞HI-TECH公司的PICC編譯器 * * 功能簡介： *
*可顯示瞬時流量和累計流量 *
*累計量定時存儲于EEPROM *
*瞬時量和累計量都可實現(xiàn)精度自動調(diào)整（小數(shù)點動態(tài)移動顯示） *
*儀表系數(shù)K可以在線置入EEPROM當中，設置同時計量工作仍繼續(xù) *
*當?shù)谝稽cK值為0時，可以作為頻率計使用 *
*儀表系數(shù)的點數(shù)可通過修改宏定義中的set 值來改變，范圍3～6點 *
*按鍵操作采用中斷方式 *
*儀表系數(shù)K默認小數(shù)部分為零 *
* *
