使用ISOTMP35-Q1和PIC32MZ2048EFM100在苛刻的应用中实现隔离的精确温度测量

/*!
 * @file main.c
 * @brief Temp ISO Click Example.
 *
 * # Description
 * This example demonstrates the use of Temp ISO Click board by reading
 * and displaying the temperature measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the temperature measurement in degrees Celsius and displays
 * the results on the USB UART approximately once per second.
