通过使用XCL105B331H2-G和ATmega328P将电池或其他电源的低电压升压到稳定的3.3V输出

 * @file main.c
 * @brief Boost 11 Click Example.
 *
 * # Description
 * This example demonstrates the use of Boost 11 click board 
 * by controlling the output state.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of GPIO module, log UART, and activate the boost operating mode.
 *
 * ## Application Task
 * The demo application reads measurements of the output voltage level [V].
 * Results are being sent to the UART Terminal, where you can track their changes.
