Function Documentation

loop()

void loop

(

)

Read and print magnetometer data in microtesla.

Definition at line 98 of file i2c_magneto.ino.

Here is the call graph for this function:

setup()

void setup

(

)

Configure I2C, verify the IMU, and initialize the magnetometer.

The magnetometer is accessed through the ICM-20948 internal I2C master, so initMag() must succeed before loop() can read magnetic field data.
