    GY-86

    I found many function in your library wich set an external (auxillary) sensor or read data from it, like: MPU6050::getExternalSensorWord(int position); Are these just cosmetic placeholders? Or do you have any example, which is useable with that? And/or do you have ANY clue, whether the dmp code you provided would work with bypass mode? This would do the trick aswell! I could bypass the magnetometer and reduce my own estimation to a filter between dmp and mag. data! And do you plan to provide a little info what exactly happens in the dmp example? It is not really obvious what is done and therfore its hard to rework it to an exernal function, where I can just say: setupDMP() and then getDMP() and that beeing it. ... Still trying arround I'd really appreciate any help really much!

    GY-86

    So this means, that there is no chance on getting the gy86 to work?! If so, could you recommend a method (with as few as possible interrupts) to get 9 DOF info about the attitude? Is the 9150 working properly? Thanks
  3. As described here: http://www.i2cdevlib.com/forums/topic/84-gy-86/%C2'> And i wonder if anyone has achieved throughpassing data with the mpu and could provide some information on how to do this! Aswell as that, for controlling a quadrotor, the raw gyro values aswell as the dmp angles would be great. Could anyone point out how to get both at the same time? Like read the raw values and dmp upon interrupt. If I get the GY-86 to work with at least the magnetometer and MPU6050 I'll provide details about how it works.
  4. I'm not an expert, but as far as I see it has something to do with timers. Servo uses timer1,.. is it possible that i2cdevlib uses it too? If so, I am going to have the same problem. Another thin would be interrupts. So that something in i2c lib interrupts during stuff in servo or so,.. but this is probably just paranoia, because I had so much trouble with that.
  5. Hey! I've got a GY-86 with MPU6050, a Barometer and the HMC5883L. On the Arduino (UNO) I get the MPU to work. But I can't figure out how to get the magnetometer data! I2C scanner tells me: Scanning... I2C device found at address 0x68 ! I2C device found at address 0x77 ! done and 0x68 is definately the mpu6050. And since I know, that it can be a master again, I suspect, that the other would be barometer and the HMC is on the slave of the MPU. Am I right with that? Can anybody tell me how I can proceed? Check my assumption or just get the mag data? Any help much appreciated!!
