SGP30 example

Hello,

did anyone have an example with SGP30-Sensor for esp-idf in C?

My sensor worked fine with an arduino-example, but I like to integrate the sensor in a big esp-idf-program.

I found only this at github https://github.com/seyriz/SGP30_ESP-IDF. It didn't work.

Re: ESP-IDF: Code for PCA8574

Thanks for the quick answer.

I forgot an important thing: I need a C sample and not CPP.

Hello,
