 * 
 * # Description
 * This application measure the intensity of the magnetic field across three perpendicular axes.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device.
 * 
 * ## Application Task  
 *  Executes one or more 'c3dhall6_log_xxx_task' functions
 *  
 *  Additional Functions :
 *
 *  - c3dhall6_log_adc_task() - performs and logs adc measurements on all channels
 *  - c3dhall6_log_volt_task() - performs and logs voltage measurements on all channels
 *  - c3dhall6_log_angleRad_task() - performs and logs angle measurements in radians on each die
 *  - c3dhall6_log_angleDeg_task() - performs and logs angle measurements in degrees on each die
