基于bmp085氣壓傳感器制作的大氣壓強、溫度、海拔高度測量儀(含詳細源代碼)

前一段時間看到一網(wǎng)店盡然有大氣壓強傳感器銷售，抓緊搞了一塊回來試試，花了兩天的時間最終把它搞定了，其中部分代碼借鑒與一網(wǎng)友的的代碼。廢話不多說先上傳測量效果照另外本項目的源代碼是模塊編程，源代碼便于閱讀，便于移植，也是一個不錯的模塊化編程例程，假如對這些代碼有任何看法或者建議的都可以提出來，感謝源代碼：/******************************************************** 項目名稱：BMP085模塊硬件功能測試 目地：BMP085模塊硬件功能測試 模塊：基本組件，12864驅(qū)動，顯示驅(qū)動，iic驅(qū)動，bmp085驅(qū)動 功能： v0.0 讀取eeprom里面11個數(shù)據(jù)，并且讀取大氣壓的值以2進制形式顯示出來 v0.1 讀取出當前氣壓值、氣溫、海拔高度，并且顯示出來 硬件要求： 主控芯片:STC89c52 測試電路板————普中科技51開發(fā)板 晶振：12.000mhz 作者 日期 備注 熊夢杰 2012/08/31 新增 熊孟杰 2012/09/01 修改 *********************************************************/#include"config.h"voidmain(){ LCD_Init(); DisplayLoading(); Init_BMP085(); for(;;) { Show_BMP085_Result(); }}/********************************************** 此頭文件干脆包含全部基本組件，便于管理、調(diào)用**********************************************/#ifndef__CONFIG_H#define__CONFIG_H#include<stc12c5a60s2.h>#include<intrins.h>#include<math.h> #include"LCD12864drive.h"#include"displaydrive.h"#include"components.h"#include"i2cdrive.h"#include"bmp085drive.h"http://typedefunsignedcharuchar;//typedefunsignedintuint;#endif/************************************************************************ 文件名：BMP085driver.c 函數(shù)功能：BMP085的基本操作函數(shù) 備注： 限制流程： 初始化（干脆讀取內(nèi)部11位eeprom數(shù)據(jù)） （1） 獲得大氣壓強未補償數(shù)據(jù)（發(fā)送限制指令-讀取數(shù)據(jù)） （2） 獲得當前氣溫值（發(fā)送限制指令-讀取數(shù)據(jù)） （3） 獲得海拔高度值（依據(jù)（2）（3）兩步得到的數(shù)據(jù)計算出結(jié)果） （4） 獲得海拔高度平均值（將（4）得到的數(shù)據(jù)分別放到10位數(shù)組中計算出平均值， 由于采納了1進1出的計算方式，因此該數(shù)據(jù)具有較好的實時性及線性效果（5） 顯示結(jié)果（通過lcd12864顯示測量結(jié)果） （6） 重復執(zhí)行步驟（2）（3）（4）（5）（6） ************************************************************************/#include"config.h" //定義傳感器內(nèi)部EEPROM存儲單元里面11個值intidataAC1,AC2,AC3,B1,B2,MC,MD;unsignedintidataAC4,AC5,AC6;unsignedcharidataAltitudeTempFlag; //計算海拔高度運用到的數(shù)據(jù)標記intidataAltitudeTemp[10]={0,0,0,0,0,0,0,0,0,0}; //海拔高度的10個臨時值，取平均值unsignedcharcodePressureTitle[16]={"氣壓溫度測量"};unsignedcharidataShowPressure[16]={"氣壓:pa"};unsignedcharidataShowTemperature[16]={"溫度:.℃"};unsignedcharidataShowAltitude[16]={"海拔:.米"};/****************************************************************函數(shù)名稱：BMP085_Read_2Byte函數(shù)功能：從BMP085讀出2字節(jié)數(shù)據(jù)入口參數(shù)：add //寄存器地址出口參數(shù)：讀取的數(shù)據(jù)備注：*****************************************************************/ intBMP085_Read_2Byte(ucharadd){ ucharmsb,lsb; intdat;Start_I2c(); //起始信號Send_Byte(BMP085_ADDWR); //發(fā)送設(shè)備地址+寫信號 if(ack==0)return(0);Send_Byte(add); //發(fā)送存儲單元地址 if(ack==0)return(0); Start_I2c(); //重復起始信號Send_Byte(BMP085_ADDWR+1); //發(fā)送設(shè)備地址+讀信號 if(ack==0)return(0);msb=RcvByte();Ack_I2c(0); //主機發(fā)送應答信號lsb=RcvByte(); Ack_I2c(1); //主機收到最終一張字節(jié)數(shù)據(jù)后發(fā)送非應答信號Stop_I2c(); //停止信號DelayMs(5);dat=msb<<8; dat|=lsb; returndat; //返回接受到的兩字節(jié)數(shù)據(jù)}/****************************************************************函數(shù)名稱：BMP085_Get_UT函數(shù)功能：讀出未補償?shù)臏囟戎等肟趨?shù)：無出口參數(shù)：未補償?shù)臏囟戎祩渥ⅲ?****************************************************************/longBMP085_Get_UT(void){Start_I2c(); //起始信號Send_Byte(BMP085_ADDWR); //發(fā)送設(shè)備地址+寫信號Send_Byte(CTRL_REG_ADD); //writeregisteraddressSend_Byte(0X2E); //writeregisterdatafortempStop_I2c(); //發(fā)送停止信號 DelayMs(CONVERSION_TIME); //AD轉(zhuǎn)換時間，溫度最大轉(zhuǎn)換時間為4.5ms return(long)BMP085_Read_2Byte(0xF6);}/****************************************************************函數(shù)名稱：BMP085_Get_UP函數(shù)功能：讀出未補償?shù)臍鈮褐等肟趨?shù)：無出口參數(shù)：未補償?shù)臍鈮褐祩渥ⅲ?****************************************************************/longBMP085_Get_UP(void){ longpressure=0;Start_I2c(); //起始信號Send_Byte(BMP085_ADDWR); //發(fā)送設(shè)備地址+寫信號Send_Byte(CTRL_REG_ADD); //writeregisteraddressSend_Byte(0X34); //低功耗模式指令Stop_I2c(); //發(fā)送停止信號 DelayMs(CONVERSION_TIME); //低功耗模式下氣壓最大轉(zhuǎn)換時間為4.5ms pressure=BMP085_Read_2Byte(0xF6); pressure&=0x00FFFF; returnpressure; }/****************************************************************函數(shù)名稱：Init_BMP085函數(shù)功能：初始化BMP085，讀出內(nèi)部標定參數(shù)入口參數(shù)：無出口參數(shù)：無備注： *****************************************************************/voidInit_BMP085(){ AC1=BMP085_Read_2Byte(0xAA); AC2=BMP085_Read_2Byte(0xAC); AC3=BMP085_Read_2Byte(0xAE); AC4=BMP085_Read_2Byte(0xB0); AC5=BMP085_Read_2Byte(0xB2); AC6=BMP085_Read_2Byte(0xB4); B1=BMP085_Read_2Byte(0xB6); B2=BMP085_Read_2Byte(0xB8);// MB=BMP085_Read_2Byte(0xBA); MC=BMP085_Read_2Byte(0xBC); MD=BMP085_Read_2Byte(0xBE);}/****************************************************************函數(shù)名稱：BMP085_Get_Param函數(shù)功能：從BMP085讀出轉(zhuǎn)換后的溫度或氣壓值入口參數(shù)：choice//bit選擇讀取溫度或氣壓，當choice=0時，返回溫度 當choice=1時，返回氣壓出口參數(shù)：temperature或pressure//long類型4字節(jié)備注：返回的溫度值為0.1℃,調(diào)用時轉(zhuǎn)換成1℃。氣壓值為Pa，調(diào)用時轉(zhuǎn)換為hPa*****************************************************************/longBMP085_Get_Param(bitchoice){ longUT; longUP; longX1,X2,B5,B6,X3,B3,p; unsignedlongB4,B7; longtemperature; longpressure; UT=BMP085_Get_UT(); //讀取未補償?shù)臏囟?UP=BMP085_Get_UP(); //讀取未補償?shù)膲簭?
