使用PD15-22C/TR8和PIC32MZ2048EFM100测量特定环境中的环境光亮度

/*!
 * \file 
 * \brief Light Click example
 * 
 * # Description
 * This application return the ambient light intensity.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - SPI and start write log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of Light Click board.
 * Measured light intensity and calculate light intensity percent from sensor,
 * results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart for aproximetly every 100 ms when the data value changes.
 *
