MPU-9150

This repository contains the source code of library for use with popular IMU sensors from InvenSense® as MPU-6500, MPU-6050, MPU-9150 and MPU-9250. Library based on "Embedded MotionDriver v5.1" and is designed for run on Atmel AVR 8-bit Microcontrollers with sufficient memory (FLASH memory size must be at least 32Kbytes and SRAM no less than 4Kbytes).

This code compiled by WinAVR (20121007) and tested on ATMega2560.

Processing demo file

At the Processing/MPUAirplane you can find a simple "Processing 2.1" sketch for visualizing the work with IMU sensors. Additional dependencies for Processing: ToxicLibs and OBJLoader libraries.

At the Processing/FlightInstruments you can find sketch with model of attitude indicator and directional gyro that simulates the earth’s horizon and сourse deviation indicator. This is a copies of the real flight instruments called an "Electric Attitude Indicator (Model: 4300)" and "Directional Gyro Indicator (Model: 3300)" by Mid-Continent Instrument Co.

NOTE

This source code does not contain any filters prevent drift from y-axis (YAW).

mpu-9150's Issues

Wrong Quaternion Output

Hi, Ferrocen

First of all , I wanna thank you so much for porting the Motion Driver code. In fact, I'm using MSP430 MCU which is supported by the Invensense code. However, the code is quite complicated with USB stuff then I found your ported code. I 've been able to read the data from fifo then the problem come out. If I read the accel and gyro data from FIFO, it'll return corectly but not for quaterion the data

As you can see, The quat[0] and quat[2] are messy while quat[1] and quat[3] are stable. If you have any suggestion, please inform me. I've stuck with it for a month. Thank you in advance

Publish Serial Data Stream for other Hardware

As I am working on an Arduino implementation with an MPU6050 I need the format you send the sensor data to the processing sketch. I can't compile with winAVR.
It would be really nice if you publish the format type (maybe one line of the serial stream) :)
Thanks!

Compatability issue with WinAVR and MVH AVR 20121007

I tried using the code base to build the hex file to run on ATMEGA 2560,
I am not able to build it on windows using latest winavr (2010 release) then as per the readme.md file..I tried it with the MVH AVR version both latest and 20121007., both are having build errors while using the following Make commands...

MAKE
MAKE ./
MAKE ./Makefile

let me know if this works in windows and especially with Win64..(if so.., please do drop the command line to build this on the windows system). OR am I missing something important here ...?
