通过使用DRV8213电机驱动器、MF25060V2-1000U-A99散热风扇和PIC18F4458实现电子系统的最佳散热管理

/*!
 * @file main.c
 * @brief Cooler Click Example.
 *
 * # Description
 * This example demonstrates the use of the Cooler click board 
 * by reading the target object temperature and controlling the cooler.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the I2C module, log UART, and additional pins.
 * After the driver init, the app executes a default configuration.
 *
 * ## Application Task
 * The demo application measures the temperature of the target object in degrees Celsius 
 * and enables a cooler if the temperature exceeds the temperature high limit value.
 * Results are being sent to the UART Terminal, where you can track their changes.
