使用AT30TSE758A和STM32G431RB以数字格式测量和报告温度

 * \brief TempLog Click example
 * 
 * # Description
 * This example returns values of the temperature from the sensor.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes Click driver.
 * 
 * ## Application Task  
 * Reads temperature from temperature register in decimal value in 9-bit resolution,
 * converts that decimal value in celsius value and checks Alert pin witch goes active (low)
 * if the measured temperature meets or exceeds the high temperature limit.
 *
