使用TMP235和STM32F410RB掌握温度控制

/*!
 * \file 
 * \brief heater Click example
 * 
 * # Description
 *  The devices resolution depends on settings applied.
 *  User should consult the datasheet and choose resolution value 
 *  that corresponds to the settings applied.
 * 
 * ## Application Init 
 *  Initialization of PWM module and start heating up
 * 
 *  ## Application Task  
 *  Durning the task device is heating up to 50 degree C and then
 *   cooling down to 40 degree C
