CMPS10 Compass

Datasheet

CMPS10 Compass Guide (.pdf)

Overview:

The CMPS10 Compass can send compass bearing data, 3-axis magnetometer and accelerometer data. It can communicate using I²C, Serial or PWM mode. You can read about these modes if you open the datasheet.

On the bottom of this page you can see an example of a working circuit, we have also provided an .ino file for you.

Specifications:

• Modes of communication:
  • I²C
  • Serial
  • PWM
• Stores these type of data
  • on 1 byte:
    • Compass bearing
    • Pitch angle (+/- 85°)
    • Roll angle (+/- 85°)
  • on 2 bytes:
    • Compass bearing (0-359.9°)
    • Magnetometer X axis
    • Magnetometer Y axis
    • Magnetometer Z axis
    • Accelerometer X axis
    • Accelerometer Y axis
    • Accelerometer Z axis

Circuit Example and Arduino Codes:

This uses the I2C bus to connect the Arduino to the CMPS10. It reads the bearing as a two byte integer (0-3599) and displays the bearing as a number 0-359 on the LCD03 display.
