Tilt Compensated eCompass, no FPU
This is a software eCompass library which requires use of a Freescale accelerometer and magnetometer
This program uses the MMA8451 & MAG3110 on a KL-46 freedom board to implement a tilt compensated eCompass with the heading displayed on the LCD. This program uses the mbed RTOS to manage the hard real time requirements of the eCompass algorithm
Improved eCompass with support for different sensor options and a new C++ wrapper
This example runs on a KL46 Freedom board using the on board MMA8451Q accelerometer and MAG3110 magnetometer. Optionally it can be used with the FXOS8700 combination accelerometer / magnetometer on a Freescale FRDM-FRS-MULTI shield.
The library output includes calibrated magnetometer values, Euler angles and Quaternions.
The object library has been compiled for a Cortex M0+ CPU and may only be used with Freescale sensors.
