I have been trying to get the BMP085 example to work and kept getting bus errors. I am using a Rev 2 board and the bus has changed from #0 to #1. The following change fixes the problem:

===========================================================================

Initialise the BMP085 and use STANDARD mode (default value)

-# bmp = BMP085(0x77, debug=True)
-bmp = BMP085(0x77)
+bmp = BMP085(0x77, debug=True)
+# bmp = BMP085(0x77)

To specify a different operating mode, uncomment one of the following:

bmp = BMP085(0x77, 0) # ULTRALOWPOWER Mode
