PlatformIO only (not tested Arduino-IDE)

Copy example code to src folder and rename main.cpp

• Modifed bmm150_defs.h using floating point

/******************************************************************************/
/*! @name        Compiler switch macros Definitions                */
/******************************************************************************/
#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
