借助 ADA4571 和 ATmega328P 进入角度和线性位置传感的新时代

/*!
 * @file main.c
 * @brief AMRAngle Click example
 *
 * # Description
 * This demo application shows the performance of AMR Angle
 * Click by reading and presenting the temperature and angle
 * results on the UART log.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Starts up the UART LOG, SPI and ADC drivers. Performs the
 * default settings like setting the adc vref, resolution and 
 * gpio pins.
 *
 * ## Application Task
 * The application task consists of reading the temperature
 * and angle data from the sensor and sending that data to the
 * UART log every second.
