Adding MPU6050 to existing 'Multiwii Pro' board

Post by Geebles »

Hi all,

So, I have the 'multiwii pro' (its not a great board, but the software is what makes it!) which can be seen here: http://www.rcgroups.com/forums/showthread.php?t=1727336 with the current specs:

• Atmega2560
• ITG3205 Triple Axis Gyro
• BMA180 Accelerometer
• BMP085 Barometer
• HMC5883L Magnetometer

I have bought an MPU6050 breakout board (http://playground.arduino.cc/Main/MPU-6050) and wired this into the I2C bus. The breakout board has two 4k7 pullups which I have REMOVED, however when the board is added and the configuration not changed at all, the ITG3205 gyro reads '0' on all data points and jumps to '200' on a random axis. When the config has been changed to use only the MPU6050 it does not read any data!!

Anyone know why? Do these devices interfere with each other or have the same I2C address?? Will I need to remove the original acc and gyro from the board?
