MSP430G2553: Inter facing with BME/BMP 280

Hello Mohamed,

Please see the thread below pointing to the I2C and SPI code examples in TI Resource Explorer.  

https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/697685?CCS-MSP-EXP430G2-SPI-or-I2C-example-code-for-MSP430-to-work-with-BME280

I also found an Energia project for interfacing with the BME280 that may be useful if you can use Energia.
