利用 MCP73213 和 STM32F103RB 快速恢复电池活力

/*!
 * \file 
 * \brief Mcp73213 Click example
 * 
 * # Description
 * This application is polymer battery charge management controller.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - SPI, also write log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of MCP73213 Click board.
 * This example sets the resistance to a given value, thus affecting the output current.
 * Controls output current using internal digital potentiometer.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on usb uart changes for every 3 sec.
