M5Stack Unit-IMU Pro BMI270/BMM150 libraries

UNIT-IMU PRO mini

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

Serial Monitor

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