使用TSYS03和STM32F031K6体验温度监测的革命

/*!
 * @file main.c
 * @brief Thermo20 Click example
 *
 * # Description
 * This example showcases the ability of Thermo 20 Click board to
 * read it's serial number. It can read themperature and measure from -40degC to
 * 120degC.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization communication modules(I2C, UART). Resets device and read Serial Number.
 *
 * ## Application Task
 * In span of ~ 1000ms it sends command for adc conversion of temperature, reads ADC value,
 * and calculates temperature in degrees C.
 * 
 * @note For this driver to work on 18bit PIC MCU-s you need to additionally pull up communication lines.
