使用 RBS240100T 和 STM32L496AG 在 360° 范围内检测 45° 倾斜

/*!
 * @file main.c
 * @brief Tilt 5 Click Example.
 *
 * # Description
 * This example demonstrates the use of the Tilt 5 Click board, which detects 
 * tilt motion using a ball switch sensor. The example initializes the device 
 * and continuously monitors the tilt state, logging changes between active 
 * and idle states.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and configures the Tilt 5 Click board.
 *
 * ## Application Task
 * Continuously reads the tilt state and logs changes. The state toggles between 
 * "ACTIVE" when a tilt is detected and "IDLE" when the sensor is in its default 
 * position.
