BSEC Lib and STM32F303

[oner]

Hi,

I tried to use BME680 sensor with STM32F303 in STM32Cube IDE (macos version). I can read gas sensor data, temp and humudity with BME680 lib. But i got below error when I tried to use BSEC lib to read IAQ data. How can I solve this issue?

Hello oner,

What is BSEC version you used?
If you use BSEC 1.4.8.0, you could compile with library "BSEC_1.4.8.0_Generic_Release\algo\normal_version\bin\gcc\Cortex_M4F\libalgobsec.a"

Hi Robin,

I am using "BSEC_1.4.8.0_Generic_Release_updated_v3", but how can I add "libalgobsec.a" data in STM32Cube. I tried to add in Project folder and add folder link in Project Includes and Source Locations. But error is still there. I added screenshots.

Hi Robin,

I crated new project and add the library only in setings, and it works. The sample code reads sensör parameters correctly. But iaq variable is 25 and 

iaq_accuracy is alwas 0. I think that it is an another problem. I will search this problem seperatly.

Thanks.

Öner.

Hello oner,

Good.

The program needs to run for a period of time until the accuracy state changes.
