double MPU6050 (Sparkfun)

[pammie]

Hello,

 

I connected 2 MPU6050's and 2 MMA8452's to a Arduino Fio. I'm using the DMP for the 6050's.

 

Altering the example code for the MMA8452 to adress them at different adresses was not that difficult. I adapted the functions to pass the device adress.

 

The example code for the MPU6050 is a lot bigger and complexer so I was wondering how I could pass the device address as a global variable. Tried some, but compiler keeps on protesting. Has someone experience with this??

 

Greetings, Pamela

Just an addition..

 

First I tried to use the specific address constructor in mpu6050.cpp

 

In my sketch it says:

 

....

MPU6050 mpu;

.....

mpu.MPU6050(MPU6050_ADDRESS_AD0_HIGH);

// actions for MPU at high address

....

mpu.MPU6050(MPU6050_ADDRESS_AD0_LOW);

// actions for MPU at low address

....

Hi pammie,

 

This would be much easier if you create two instances of the device:

MPU6050 mpu1(MPU6050_ADDRESS_AD0_LOW);
MPU6050 mpu2(MPU6050_ADDRESS_AD0_HIGH);

Then simply use them as independent objects. The device constructor is meant to take the slave address as an optional parameter for this purpose.

Hai Jeff,

 

that is a nice solution,

 

thanks, greetings, Pamela
