使用Nixie Power Click和STM32G474RE为尼克管提供所需的高电压

 * @file main.c
 * @brief Nixie Power IN-12B Click example
 *
 * # Description
 * This example demonstrates the use of Nixie Power IN-12B Click board by displaying
 * digits from 0 to 9 in sequence and then setting a comma indicator.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Sequentially displays digits 0 through 9 on a IN-12B display, with a 1-second delay
 * between each digit. After displaying all digits, it clears the digits and enables
 * a comma indicator on the display. Each operation is logged on the USB UART.
