I now have working C code that queries current temperature from the Bosch BMP085 temperature/pressure/altimeter sensor. I'd been frustrated with the sensor for awhile as I couldn't extract an intelligible answer from it. After peeking at someone else's code, I realized that the least and most significant 8 bits in the queries 16-bit word were reversed. Fixed that and suddenly it works. I'll start posting notes once I have the code working for the pressure and sensor readings.
