The tutorial I linked to is for the Adafruit one. I hadn’t noticed it was SPI and i2c, ops.
I should have looked a little closer. I had assumed, wrongly I guess, the library would work with any i2c BME680. I wonder if its because the Adafruit one may be useing a different i2c address?
I have two BME680’s, both are connected to Raspberry Pi’s though. I have an UNO and an MKR but haven’t done very much with them yet. It’s something I’ve been meaning to rectify. I have plans to get into Arduino after Christmas. I have a Pi 4B earmarked to run the Arduino IDE on for the best of both worlds.
Right now though my Arduino skills are pretty basic.
