|
|
* This is a library for the QMC5883P 3-axis magnetometer
|
|
*
|
|
* These sensors use I2C to communicate, 2 pins (SCL+SDA) are required
|
|
* to interface with the breakout.
|
|
*
|
|
* Adafruit invests time and resources providing this open source code,

* please support Adafruit and open-source hardware by purchasing
|
|
* products from Adafruit!
