Unveil the true potential of digital signals using LTC2601 and PIC18F57Q43

 * \brief Dac2 Click example
 * 
 * # Description
 * DAC 2 click represents a 16-bit digital-to-analog converter.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * This example of the DAC 2 communicates with MCU through the SPI communication, 
 * send digital input ( form 0 to 100 with step 1 ) and transforms it 
 * to the output voltage, ranging from 0 to Vref [mV].
