HEllo..
I want to see magnetcompass data in matlab but now on, I don't know how to do,
What I confussed is i2c program.
You know that qmc5883L is I2c device.

And it's OKay to use in arduino sketch using this library.

However, when I write a code in matlab,readRegister, I don't know how to do.

It's find to do dev and uint16 but, I don't know how to use register.
So I was check 1 to 255 value and that is this.

I'm sorry about this large Matrix...
I don't know how to use this to show x y z and azimuth value.
Please help me :frowning:

We can't help with Matlab questions.

Most us don't have it.

have you read thru
Matlab support for arduino

and managed to get a simple program such as blinking a LED operational?

post your matlab code?

if you are going to control the QMC5883L directly from Matlab you will have to send the commands to configure the device and read information.

it may be simpler to use the QMC5883L arduino library and then transmit the data to Matlab using Serial.print() etc as in the example code

then use the Matlab serial interface to read the information
