使用 STPD01 和 MK64FN1M0VDC12 实现灵活的电源调节

 * @file main.c
 * @brief Buck 19 Click example
 *
 * # Description
 * This example demonstrates the use of Buck 19 Click board by
 * iterating through the entire output voltage range.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Changes the output voltage every 3 seconds and displays on the USB UART
 * the currently set voltage output value.
