    Why don't you consider a SD-card through SPI?

    More particulars - what giving you problems, how long do you need to store, etc.
    (The quick answer is put the readings in an array - then they are stored.  But maybe you want to do something more than that.)

    Hi
     
    have a look on datasheet pages 37..39 for the pinout (I2C or SPI) and
    here https://ae-bst.resource.bosch.com/media/products/shuttleboards/BMP280_Shuttleboard_Flyer.pdf for the corresponding pins on the "shuttel board"
     
    MSP432 Launchpad pin map here: http://energia.nu/wordpress/wp-content/uploads/2015/03/MSP432-LaunchPad-%E2%80%94-Pins-Maps.jpg
     
    Arduino example + code here (if you plan to use Energia): http://www.seeedstudio.com/recipe/257-bosch-bme280-1-chip-temp-humidity-pressure.html(<- you don't need the level shifter!)
