使用ATmega644实现液体浊度水平的连续实时监测

/*!
 * @file main.c
 * @brief Turbidity Click example
 *
 * # Description
 * This library contains API for the Turbidity Click driver.
 * The demo application reads ADC value, ADC voltage and 
 * Nephelometric Turbidity Units ( NTU ).
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * After driver initialization, default settings turn on the device.
 *
 * ## Application Task
 * This example demonstrates the use of the Turbidity Click board™.
 * In this example, we monitor and display Nephelometric Turbidity Units ( NTU ).
 * Results are being sent to the Usart Terminal, where you can track their changes.
