BME680 how to calculate CO2 equivalent and VOC?

[Mich]

Hello,

How can I calculate CO2 equivalent and VOC without library?

I did not find any formula neither in the BME680 datasheet nor in the API...

Best regards

The BME680 alone can only output raw temperature, absolute pressure, relative humidity and gas resistance. CO2-equivalent like IAQ and other advanced outputs are features of and only available from the BSEC software library.

Why? You do not want people to use your device?

How could I for for MSP430 with IAR?

Is gcc library ok?

Due to the complex nature of the algorithms, the BME680 alone couldn't run these calculations.

You can find the the platform and compiler combinations support by default on the BSEC page or inside the BSEC release package. In the standard release, the MSP430 is supported for the msp430-elf-gcc compiler. If you cannot find support for your specific platform requirements in the standard release, you may share your exact MCU part number and compiler use (including version and flags), and our team will evaluate whether we could generate a release for your platform.

Ok, I sent an email to request the library for MSP430F5326 IAR IDE.
