This is a library for the Adafruit BMP085 Barometric Pressure + Temp sensor Designed specifically to work with the Adafruit BMP085 Breakout ----> https://www.adafruit.com/products/391 These displays use I2C to communicate, 2 pins are required to interface Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!

Check that the Adafruit_BMP085 folder contains Adafruit_BMP085.cpp and Adafruit_BMP085.h Place the Adafruit_BMP085 library folder your <arduinosketchfolder>/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE. ----------------------------------- This library is derived from the Adafruit (HW i2c) example code for the BMP085 pressure sensor. I've renamed the library files to swI2C_BMP085.cpp/.h so that it won't conflict with the Adafruit_BMP085 library. This code allows you to use the 3.3v BMP with Adafruit's Data Logging Shield, or it allows you to connect multiple BMP085's to a single Arduino. this requires the I2cMaster library from http://forums.adafruit.com/download/file.php?id=4712
