重新定义您的SPI信号电平转换体验，使用STM32F410RB

/*!
 * \file 
 * \brief llcspi Click example
 * 
 * # Description
 * This application is converter for logic signals.
 *
 * The demo application is composed of two sections : 
 * 
 * ## Application Init 
 * Initialization device init
 * 
 * ## Application Task  
 * Counter passes through the loop and logs the value of the counter on the bargraph display
 * 
 * *note:* 
 * Connection between BarGraph and LLC-SPI is made through SPI interface.
 * You can connect a BarGraph click to LLC-SPI click with the wires to make connection between click boards.
 * We use the BarGraph click to demonstrate the functions of the LLC-SPI click.
