While on the topic of this magnetometer, I have a Processing sketch that plots the x/y/z/heading and Bt. I'm using scaled values to determin my heading and getting pretty good results.
My problem is that I'm using Serial.write() to send the signed integers to Processing. Since each axis has two registers, and sends 2 bytes, I'm getting mixed values on the Processing end.
How do I go about sending each axis MSB and LSB, and then join the two once they are read in Processing? I have searched forums and reference pages for days, and have not made
any progress. I am storing the incoming bytes into an array in processing. Any help would be appreciated.
Also, the good results I am getting are via the HMC5883L library instead of calling addresses on the I2C directly. I'm allowing the library to do the heavy lifting. Thanks in advance for
any assistance
