使用 VO617A 和 STM32L073RZ 实现自动捕捉功能

/*!
 * @file main.c
 * @brief Shutter Click Example.
 *
 * # Description
 * This example demonstrates the use of Shutter Click board by taking pictures
 * with and without auto focus function.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Swithes ON the auto focus function and triggers the shutter to take the picture, then
 * swithes OFF the auto focus and triggers the shutter. The shutter is triggered every 13 seconds
 * approximately. All data is being logged on the USB UART where you can track the program flow.
