使用 DRV81004-Q1 和 STM32L496AG 强化工业 PLC 应用

/*!
 * @file main.c
 * @brief Solenoid Driver Click example
 *
 * # Description
 * This example demonstrates the use of the Solenoid Driver Click board by 
 * enabling output channels one by one in a round-robin fashion and parsing 
 * the diagnostic status after each update. The diagnosis includes 
 * undervoltage detection, output fault status, and operation mode.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and the Click board driver, and applies the default configuration.
 *
 * ## Application Task
 * Sequentially enables each output channel with a 1-second delay, 
 * checks the diagnostic register, logs operation status, and clears the latch register.
