CM1020 COMPASS MODULE
Applications Information
Data Format
The registers of the CM1020 are grouped into two byte words. The Heading data is in hex, with the actual
direction degrees multiplied by 10. In other words, a reading of 1376 would mean that the heading is 137.6
degrees. The remaining data registers are in 2‘s complement format.
