LSM303AH

[Samuel Schalkwyk]

Good day

I have a STEVAL-MKI173V1 which is for the LSM303AH.

I have to integrate this on a project in VS code, as there is no Zephyr driver for this, I am trying to implement this directly on I2C.

The device has two addresses one for the accel and the other for the magn, the supplied addresses 

/** I2C Device Address 8 bit format **/

#define LSM303AH_I2C_ADD_XL       0x3B

#define LSM303AH_I2C_ADD_MG       0x3D

does not respond when a "device is ready" check is done, I don't see any other addresses in the datasheet.

 

I got these from the header file, supplied under HAL

I must be missing something, I have tested other I2C devices on the same port and it works just fine.

 

Thanks in advance
