使用TPIC6A595和PIC32MZ2048EFM100体验无缝的I/O引脚扩展

/*!
 * \file 
 * \brief Expand4 Click example
 * 
 * # Description
 * Example demonstrates use of Expand 4 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - Clear TPIC6A595 register and start write log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of Expand 4 Click board.
 * In this example, the LED pin mask is transferred via SPI bus,
 * LEDs connected to D0-D7 pins are lit accordingly by turning ON LEDs from D0 to D7 for 3 sec.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart for aproximetly every 3 sec. when the change pin who is connected.
