The Bosch BME280 pressure-temperature-humidity sensor is very popular for projects because there are breakout boards available from Adafruit and Sparkfun as well as a large library of code to interface it to Arduino MCUs. Not so much for the MSP430, especially transparent code to understand what is happening at the register level. I have written and tested some demo C-code that hopefully fills that gap. It sacrifices generality and efficiency for compactness and transparency. I use the F5529 Launchpad and communication with the sensor is via SPI using the UCB0 module. I2C is also availab
