This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the InvenSense MPU9250.
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
- Read accelerometer (raw, micro-g's), gyroscope (raw, micro-dps), magnetometer data (raw, gauss (untested/unverified), nano-Teslas (untested/unverified))
- Set accel, gyro full-scale, mag ADC res
- Data-ready flags
- Interrupt support: pin active state, output type, latching, read state
- Set magnetometer ADC resolution
- Set bias offsets
- Set output data rates
- Set optional accel/gyro/temp data low-pass filter
- Magnetometer calibration
- Clock source: internal oscillator, automatic
- FIFO modes, status flags
