This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the InvenSense MPU6050.

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.

Salient Features

  • I2C connection at up to 400kHz
  • Read accelerometer (raw, micro-g's), gyroscope (raw, micro-dps)
  • Set accel, gyro full-scale
  • Data-ready flags
  • Interrupt support: pin active state, output type, latching, read state
  • Set bias offsets
  • Set output data rates
  • Set optional accel/gyro/temp data low-pass filter
  • Clock source: internal oscillator, PLL w/gyro. reference, external
  • FIFO modes, status flags

Requirements

P1/SPIN1:

  • spin-standard-library
  • 1 extra core/cog for the PASM I2C engine
  • sensor.accel.common.spinh (provided by spin-standard-library)
  • sensor.gyroscope.common.spinh (provided by spin-standard-library)

P2/SPIN2:

  • p2-spin-standard-library
  • sensor.accel.common.spin2h (provided by p2-spin-standard-library)
  • sensor.gyroscope.common.spin2h (provided by p2-spin-standard-library)

Compiler Compatibility

Processor Language Compiler Backend Status
P1 SPIN1 FlexSpin (6.9.4) Bytecode OK
P1 SPIN1 FlexSpin (6.9.4) Native/PASM OK
P2 SPIN2 FlexSpin (6.9.4) NuCode OK
P2 SPIN2 FlexSpin (6.9.4) Native/PASM2 OK

(other versions or toolchains not listed are not supported, and may or may not work)

Limitations

  • Very early in development - may malfunction, or outright fail to build
  • I2C sensor slaves not supported (not currently planned)
  • DMP not supported (not currently planned)
