Could you please let me know where i can fine tMPU9150 structure?

It is at "\\sensorlib\mpu9150.h"

Thanks

Could you please answer this question as well?

MPU-9150 just have one I2C address, How do we can have access for individual register in the MPU9150?

or we have to read all the register with just one address?

I am a little bit occupied to help. But, you can find the answer by going through the MPU9150 datasheet and reviewing the compdcm_mpu9150 example program.

Hello Majid,

Yes, the slave device has just one address. The means to access the register is to first write the address of the register after the Slave device as a data byte and then do a write to the register, This is mentioned in the MPU9150 data sheet.

Hi,

Thanks for your reply. I  looked at mpu9150.h but i did not understand too much,

could you please let me know whether you have a document to help me to have better understanding of the data structure?

thanks

Hey Majid,

the data structure is simply a consistent software help for the interface you normally would have to program yourself. I'd recommend the following documents

• MPU9150 Product Specification
• MPU9150 Register Map

With an understanding of the sensor and its interface itself it shouldn't be hard to follow up on what the software is doing.

Sincerely,

Michel
