Esp32 compiling guide

[carbonadam]

I can not seem to get these sketches to compile. I am using arduino IDE 1.8.5 and a doit esp32. i can read i2c devices on the i2c pins fine but I get the following when trying compile the BNO055_MS5637_ESP32 Basic Example Code.

Yeah, you need to add the extra filequaternionfilters.ino as an additional file in the tabs, or just comment out MagwickQuaternion in the main sketch.
