使用 TLC59401 和 ATmega328 实现平稳的舵机电机运动

/*!
 * @file main.c
 * @brief Servo 2 Click example
 *
 * # Description
 * This example demonstrates the use of the Servo 2 Click board for controlling the angle of servo motors. 
 * The board is capable of driving multiple servos, and the example illustrates how to change the angle 
 * of all connected servos simultaneously within a defined range.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger module and configures the Servo 2 Click board. The PWM communication is 
 * established, and the device is prepared for controlling the servos.
 *
 * ## Application Task
 * Gradually changes the angle of all connected servo motors from a minimum to a maximum value, and 
 * then back to the minimum, creating a sweeping motion. The current angle is logged during each update.
 *
 * @note
 * Ensure that the servo motors are properly connected to the Servo 2 Click board and are compatible 
 * with the specified angle range such as the SG90 Micro Servo motors.
