BMI270 and BMM150 Orentation and BMI270 I2C address = 0x69

## PlatformIO only (not tested Arduino-IDE)

Copy example code to src folder and rename main.cpp

- Modifed bmm150_defs.h using floating point

#define BMM150_USE_FLOATING_POINT //OK

#ifndef BMM150_USE_FLOATING_POINT /*< Check if floating point (using BMM150_USE_FLOATING_POINT) is enabled */

#ifndef BMM150_USE_FIXED_POINT /*< If floating point is not enabled then enable BMM150_USE_FIXED_POINT */

#define BMM150_USE_FIXED_POINT

#endif

#endif

## Serial Monitor

To keep the display speed, use M5.Log.Printf instead of Serial or USBSerial
