使用SX8633和STM32F031K6扩展电容输入数量

/*!
 * \file 
 * \brief CapExtend Click example
 * 
 * # Description
 * This example showcases the initialization and configuration of the logger and click modules
 * and later on shows how to read and display the 16-bit button map ( LSB + MSB ).
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the click and logger modules.
 * 
 * ## Application Task  
 * This function collects map data and displays the 16-bit button map, where each bit that has
 * the value 1 represents a button that has been pressed.
