使用23LC1024和PIC18F57Q43体验无缝多任务处理和快速数据处理

 * \brief Sram Click example
 * 
 * # Description
 * SRAM Click presents additional 1Mbit SRAM memory that can be added to device.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * SRAM Click communicates with register via SPI protocol by write data to and read data from 23LC1024 Serial RAM device. 
 * Results are being sent to the UART where you can track their changes. 
 * All data logs on USB UART for aproximetly every 1 sec.
