This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the NXP FXOS8700 6DoF IMU.
IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.
- I2C connection at up to 400kHz
- Supports default or alternate I2C address
- Manually or automatically set bias offsets (on-chip)
- Accelerometer built-in self-test
- Read accelerometer data in ADC words or micro-g's
- Read magnetometer data in ADC words or micro-Gauss
- Read temperature (C, F, K)
- Set output data rate (accel+mag locked, in active and low-power operating modes)
- Set power state
- Set accelerometer full-scale
- Set interrupt flags, INT1/2 pin active state
- Set accelerometer data oversampling/power mode (in active and low-power operating modes)
- Output data filtering: high-pass
- Read flags: data ready (accel, mag), data overrun (accel, mag), interrupts
- Orientation detection
- Click/Pulse/Tap detection
- Free-fall detection
- Inactivity detection/auto-sleep
- FIFO control and flag reading (set watermark, set circular buffer or FIFO mode, flag if full, number of unread samples)

- If both accel and mag sensors are enabled, data rate is halved (chip limitation). Currently, the data rate setting methods don't reflect this
