使用SST26VF064B和ATmega328P提供无与伦比的数据吞吐量

 * @file main.c
 * @brief SqiFlash Click example
 *
 * # Description
 * This is an example that demonstrates the use of the SQI FLASH Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * SQI FLASH Driver Initialization, initializes the Click by setting mikroBUS to
 * approprieate logic levels, performing global block unlock and chip erase functions,
 * reads manufacturer ID, memory type and device ID and logs it on USB UART terminal.
 *
 * ## Application Task
 * Writing data to Click memory and displaying the read data via UART.
