After a lot of trial and error for the order that the 2 code pieces display their resp. data to LCD and serial monitor, I got both sensors to print to the LCD while keeping the BMP180 serial display:
CODE:
#include <LiquidCrystal.h>
#include <Wire.h>
#include <Adafruit_BMP085.h>
Adafruit_BMP085 bmp;
int ThermistorPin = 0;
int Vo;
float R1 = 9900;
float logR2, R2, T;
float c1 = 1.009249522e-03, c2 = 2.378405444e-04, c3 = 2.019202697e-07;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
Serial.begin(9600);
bmp.begin();
}
void loop() {
Vo = analogRead(ThermistorPin);
R2 = R1 * (1023.0 / (float)Vo - 1.0);
logR2 = log(R2);
T = (1.0 / (c1 + c2*logR2 + c3*logR2*logR2*logR2));
T = T - 273.15;
T = (T * 9.0)/ 5.0 + 32.0;
//conv C
T = (T - 32) / 1.8;
lcd.print("Temp = ");
lcd.print(T);
lcd.print(" C");
delay(2000);
lcd.clear();
Serial.print("TempBMP(C)= ");
Serial.print(bmp.readTemperature());
lcd.print("TempBMP(C)= ");
lcd.print(bmp.readTemperature());
delay(2000);
lcd.clear();
Serial.print(" Pressure (Pa)= ");
Serial.print(bmp.readPressure());
lcd.print("Pres(Pa)=");
lcd.print(bmp.readPressure());
delay(2000);
lcd.clear();
Serial.print(" Altitude (m)= ");
Serial.print(bmp.readAltitude());
lcd.print("Alt(m)= ");
lcd.print(bmp.readAltitude());
Serial.println();
delay(2000);
lcd.clear();
delay(2000);
lcd.clear();
}
This had to be space compressed and abbreviated etc. to fit on the LCD, but can be seen that the print line has to be followed immediately by the respective sensor read line to get the next data value e.g .(bmp.readTemperature(), from the unit to follow the LCD text:
Serial.print("TempBMP(C)= ");
Serial.print(bmp.readTemperature());
lcd.print("TempBMP(C)= ");
lcd.print(bmp.readTemperature());
delay(2000);
lcd.clear();
In the SFE180 example code, altitude is set as the constant:
SFE_BMP180 pressure;
#define ALTITUDE 1540 // Altitude of SparkFun's HQ in Boulder, CO. in meters so maybe this an be added...
In this code, you can add your current pressure, but still gives wrong Alt...?:
This is an example for the BMP085 Barometric Pressure & Temp Sensor
Designed specifically to work with the Adafruit BMP085 Breakout
