You can find the original libary here:
http://www.varesano.net/files/FreeIMU-20121122_1126.zip
It is not form me. I am not at home now, so I can not send you the changed one, but it is mainly replacing the int with int16_t.

Ok, I still have no success with the i2cdevlib but i manged to use the MS5611 using Flavio Varesano freeimu libary.
After some minor changes the raw reading function of the libary works well on the due.

Hi I try to talk to an MS561101BA on the due.

The newest version of i2devlib works well on the due with HMC5883L MPU6050 and BMP085.
https://github.com/jrowberg/i2cdevlib

For the MS561101BA  I use the library made by Manuel J Guisado using i2devlib, which works just fine on the arduino uno.
https://github.com/mjguisado/i2cdevlib/tree/master/Arduino/MS561101BA

There is no example but this is an minimal one which works on the uno (sensor powered with 3.3V and pullups disabled):

Code:

#include "Wire.h"
#include "I2Cdev.h"
#include "MS561101BA.h"
MS561101BA baro(0x77); // address of the sensor on freeimu 0.4
float pressurem;
float temperaturem;

void setup() {
    Wire.begin();
    Serial.begin(57600);
    baro.initialize();
    Serial.println(baro.testConnection() ? "baro connection successful" : "baro connection failed");
    // this gives false positive value on the due I think due to the problems with wire ?
}

void loop() {
baro.setOverSampleRate(256);
baro.readValues(&pressurem, &temperaturem);
Serial.print(pressurem); Serial.print("\t");
Serial.print(temperaturem); Serial.println("\t");
}

I get no error message while uploading to the due, but it only prints 0 values for temperature and pressure.

Any idea is appreciated.

Have a look at this thread:
http://arduino.cc/forum/index.php?topic=135439.0

Since the SPI port is not at the same posiition on the due the shield might not work.

But you do not need the shield. The due has 3.3V operating voltage you could directly connect the SD card to the due spi port.

Can you please share your code for the MPU6050?

Thanks for the libary and the pin maps.

I am a arduino noob and i managed to access the SD on the Due.
I use direct wires to a sd card socket and the following pin connections:

DUE	SD	SPI
MOSI	CMD	DI
MISO	DAT0	DO
SCK	CLK	SCK
D10	CD/DAT3	CS
3.3V	VDD	VDD
GND	VSS	VSS
GND	VSS2	VSS2

I get this for a cheap 2GB san disk SD
