使用PCA9532和STM32G431RB轻松打造令人惊叹的灯光效果

 * @file main.c
 * @brief LEDDriver12 Click example
 *
 * # Description
 * This example demonstrates the use of LED Driver 12 click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration which turns OFF
 * the LEDs 0 to 7, configures LEDs 8 to 11 for PWM0, and LEDs 12 to 15 for PWM1 settings.
 * PWM0 is set at half duty cycle with a one-second blinking period, while PWM1 is configured
 * for a quarter of duty cycle with a half-second blinking period.
 *
 * ## Application Task
 * Toggles the LEDs 0-7 every 2 seconds and displays their state on the USB UART.
