使用MAX31855K和PIC18F45K42保持理想的温度条件

/*!
 * \file 
 * \brief Thermo Click example
 * 
 * # Description
 * This application collects data from the sensor, calculates it, and then logs
 * the results.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and star write log.
 * 
 * ## Application Task  
 * Temperature measured by the thermocouple is converter by MAX31855 sensor 
 * and the results are logged. Displayed temperature is in degrees Celsius.
