Craft seamless signals for mobile communication systems with HT9200A and STM32F091RC

/*!
 * @file main.c
 * @brief DTMF Generator Click Example.
 *
 * # Description
 * This is an example which demonstrates the use of DTMF Generator Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables - GPIO,
 * run the power-on sequence, also write log.
 *
 * ## Application Task
 * DTMF Generator click board DTMF generator transmits the signal 
 * for generating tone for digits :
 * "0", "1", "2", "3", "4", "5", "6", "7", "8", "9",
 * "A", "B", "C", "D", "*" and "#".
 * All data logs write on USB uart changes.
