Pmod CMPS2 example for Arduino

[pasicr]

Hi there, I use Pmod CMPS2 example with Arduino, https://reference.digilentinc.com/reference/pmod/pmodcmps2/start

code work OK like compass, but I need to use the sensor like magnetic field sensor and get value from sensor for X, Y and Z value of

magnetic filed in mG (that is implemented in code but the final result on serial monitor is compass value, not 3 axis magnetic field values)

Can somebody help me with advice or code?

Thanks

Hi @pasicr,

The code as is won't provide you the mG values as those are set as private variables within the corresponding .h file. You could adjust the library code to make the x, y, and z values public, or it looks like you may be able to call the getX, getY, and getZ in the Arduino code which should return the values you are looking for (albeit for a single sample rather than an average).

Thanks,

Thanks for info, I will try to change library code, one more question about Set/Reset function, how can I call this function in void loop()?

First call set after that call reset? is it correct?

Hi @pasicr,

The Set and Reset functionality is not individually implemented in the library. It looks like the Set command is part of the init and removeOffset functions based on the description listed in the cpp library though.

Thanks,
