使用DTH-08和STM32F031K6在信号的上拉或下拉状态之间切换

 * @brief EasyPull Click Example.
 *
 * # Description
 * This example demonstrates the use of PIR 2 Click boards.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and USB UART logger.
 *
 * ## Application Task
 * It checks the state of the pins and displays their state on the USB UART.
