Freescale offers tilt-compensated e-compass and magnetic calibration software as part of the Freescale Sensor Fusion software library. The ecompass functions in the Sensor Fusion library use data from accelerometer and magnetometer sensors to provide an accurate magnetic compass heading corrected for orientation and hard and soft iron magnetic interference. Target applications are any mobile, consumer, or Internet of Things product that needs a compass. These applications expand beyond smartphones, tablet PCs and portable navigation devices to wearables, fitness bands, and gaming products.
The Freescale Sensor Fusion library is offered as Open Source with the MEMS Industry Group. The e-Compass portion can be applied to any accelerometer and magnetometer combination.
The FRDM-SFUSION Sensor Fusion development kit brings together the Freescale Sensor Fusion software library. with Freescale Freedom development boards for application development and rapid prototyping. This kit makes it easy to bring your next sensor-based design to life with comprehensive hardware and software solutions.
