I finished up my first Energia project, a template library for the Bosch BMP085 temperature and pressure sensor. It uses I2C and supports temperature in Celsius and pressure in Pascal. https://github.com/astuder/BMP085-template-library-Energia I connected the GY-80 breakout commonly found on eBay, but it should also work with most other BMP085 breakouts, like the ones from Adafruit or Sparkfun. Note that I had to patch Energia to make 1-byte read work on MSP430G2553 with Rev1.5 LaunchPad. I also had to remove the LED2 jumper, probably due to too weak I2C pull-up. Update: Tested on La
