   Here is their initialization code:

    i2c_LIS2MDL_Read_8Bit(LIS2MDL_WHO_AM_I, &b);

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_OFFSET_X_REG_L,0x00);

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_OFFSET_X_REG_H,0x00);

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_OFFSET_Y_REG_L,0x00);

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_OFFSET_Y_REG_H,0x00);

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_OFFSET_Z_REG_L,0x00);

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_OFFSET_Z_REG_H,0x00);

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_CFG_REG_A,0b10001100);// temp comp, continuous 100hz data rate

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_CFG_REG_B,0b00000010);// offset cancellation enabled

    i2c_LIS2MDL_Write_8Bit(LIS2MDL_CFG_REG_C,0b00010000);// block data

Does anything need to be modified or added?  Thank you.

You configuration is correct.

What kind of issue do you have? Can you please be more specific.

Customer is not able to get the auto offset cancelation working.

It is very vague statement.

Please provide register dump and datalog of X,Y,Z data with and without offset cancellation.
