 * @brief ML Vibro Sens Click example
 *
 * # Description
 * This example demonstrates the use of the ML Vibro Sens Click board by capturing and logging
 * acceleration data on the X, Y, and Z axes, along with temperature readings. The data is output 
 * over USB UART and can be visualized in real-time using tools like SerialPlot. Additionally, 
 * the vibro motor state changes periodically, cycling through different vibration states for 
 * added feedback.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the communication interface and configures the ML Vibro Sens Click board 
 * with default settings. This setup enables an interrupt on the INT pin when data is ready,
 * sets the acceleration sensitivity to a +/-4G range, and sets the output data rate to 100 Hz.
 *
 * ## Application Task
 * Monitors the data-ready interrupt, retrieves acceleration and temperature data when available,
 * and logs it over USB UART in the format X;Y;Z;TEMP. After every 1000 data readings, the 
 * vibro motor state cycles through predefined states to demonstrate the motor's functionality.
 *
 * @note
 * We recommend using the SerialPlot tool for data visualization. The temperature measurements
 * should be visualized independently. The data format for plotter is as follows: X;Y;Z;TEMP;
