 * \brief VToHz2 Click example
 * 
 * # Description
 * This appliaction enables usage of a converter for analog voltage input signal into a pulse wave signal of a certain frequency.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and enables the click board.
 * 
 * ## Application Task  
 * Sets the output frequency by incrementing the pwm duty cycle from 0 to 100% in an infinite loop.
 * Results are being sent to USB UART terminal.
