Read a magnetometer value of MPU9250 using myRIO

[장태호]

Hi,

I'd like to read a value of a magnetometer of MPU9250 using myRIO.

I built a labview code with reference to arduino library for MPU9250(attached library).

(can download the library here: https://learn.sparkfun.com/tutorials/mpu-9150-hookup-guide#installing-the-arduino-library)

Now, I can read a value of an acceleration and gyro of MPU9250 in real time, but  value of magnetometer is measured just once, at first loop time. i can't read the value in real time.

I attached the labview code, I ask for your help. thanks

is is an old thread but just for the record, the magnetometer AK8963 needs you to read more than 6 bytes. I put 8 bytes to read in the last vi and it sprang to life! Apparently this is in the data sheet of the AK8963. This is a real dog of a thing to get going. See modified attached.
