Introduction
The CMPS12 is Devantech's 4th generation tilt compensated compass. Employing a 3-axis magnetometer, a 3- axis gyro and a 3-axis accelerometer. At the core of the module is the superb BNO055 running algorithms to remove the errors caused by tilting of the PCB. Power supply requirements are flexible, you can feed between 3.3 - 5v and the module draws a nominal 18mA of current. A choice of serial or I2C interfaces can be used for communication. The CMPS12 command set and pinout is compatible with the older CMPS11. The sensor calibrates itself continuously and automatically with movement and the resulting calibration profile may be saved on the module.
Mode selection and connections
Serial or I2C mode is easily selected with the state of the mode pin. Note the CMPS12 looks at the
mode selection pin at power-up only.
For I2C the mode pin can be left open or pulled to the supply voltage, for serial mode
the mode pin should be connected to 0v ground.
