Bluno M3 v2.1 With HMC5883l Compass

Hello,

I am trying to get the HMC5883L compass to work with my new Bluno M3 v2.1 - The code is quite simple, but I am getting garbage for readings

In setup

Wire.beginTransmission(0x1E);
Wire.write((byte)0x02); // set to continuous mode
Wire.write((byte)0x00);
Wire.endTransmission();


Then to read the 6 bytes in loop (with a delay)

Wire.requestFrom(0x1E,6);
if(6<=Wire.available()){
x = ((int16_t)Wire.read()<<8) | Wire.read();
z = ((int16_t)Wire.read()<<8) | Wire.read();
y = ((int16_t)Wire.read()<<8) | Wire.read();
}

I suspect the MSB/LSB logic may be different for this microcontroller?
Has anyone tried this with success?


Thanks a lot!
Tom
