使用FOD4216和STM32G474RE在嘈杂的工业环境中保持信号准确性

 * @file main.c
 * @brief Opto 5 Click Example.
 *
 * # Description
 * This example demonstrates the use of Opto 5 click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of UART LOG and GPIO pin drivers.
 * The output of PWM is set to high so the optocoupler
 * is not triggered by default.
 *
 * ## Application Task
 * The output pin is toggled every 5 seconds.
