Data and clock pins BMP085

Post by paysan »

I use the BMP085test example.

They say I have to connect the data and clock lines to the Analog 4 and 5 pins.

Where is this defined? I want to use different pins.

I checked the Adafruit_BMP86.h and cpp but did not find it in there.

The BMP085 is an I2C device. Analog 4 and 5 are the hardware I2C pins on the Arduino Uno. This is a function of the processor hardware.
To change pins you would have to re-write the driver to use "Soft i2c" https://code.google.com/p/rtoslibs/downloads/list
